BACKGROUND

[0003] As the average life span increases, increasing emphasis is placed upon "healthy aging." Individuals would like to live more active lifestyles as they age, and as a result, many aging disorders can have a significant impact on the quality of life of aging individuals. Treatments directed to regenerative ends have utility for treating aging diseases. Additionally, many treatments for aging disorders can be applicable to younger individuals who have suffered illness, injury, or who possess genetic or developmental defects leading to premature tissue loss, wasting, or weakening.

SUMMARY

[0004] As individuals age, tissue progenitor cells lose their regenerative potential. Described herein, in certain aspects, are heparin-associated polypeptides that can restore some or all of this regenerative potential, and are thus useful in the treatment of aging disorders that result in tissue loss or underperformance, and rehabilitation from injury. Described herein are therapeutic compositions comprising heparin-associated polypeptides and methods of treating disorders associated with aging, injury, or illness. In certain embodiments, the therapeutic compositions comprise one or more heparin-associated polypeptides that possess mitogenic (i.e., regenerative) and/or fusion promoting activity to a somatic cell, such as a tissue progenitor cell. In certain embodiments, the therapeutic compositions have activity towards muscle and soft tissue progenitor cells.

[0077] In the following description, certain specific details are set forth in order to provide a thorough understanding of various embodiments. However, one skilled in the art will understand that the embodiments provided may be practiced without these details. Unless the context requires otherwise, throughout the specification and claims that follow, the word "comprise" and variations thereof, such as, "comprises" and "comprising" are to be construed in an open, inclusive sense, that is, as "including, but not limited to." As used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the content clearly dictates otherwise. It should also be noted that the term "or" is generally employed in its sense including "and/or" unless the content clearly dictates otherwise. Further, headings provided herein are for convenience only and do not interpret the scope or meaning of the claimed embodiments.

[0078] As used herein a composition that is "consisting essentially" of the recited components is a composition that only has the recited elements as active ingredients, but can comprise other non-active components that do not appreciably modify the function or activity of the recited components. Any list disclosed herein that is recited as "comprising" can be recited as "consisting essentially," to exclude non-recited polypeptide or protein components.

[0079] As used herein "heparin-associated polypeptide" means any polypeptide that directly binds to heparin with a K.sub.D of less than 1 micromolar, or any polypeptide that associates with one or more polypeptides that bind directly to heparin with a K.sub.D of less than 1 micromolar. This K.sub.D can be measured using a method such as surface plasmon resonance. See e.g., Nguyen et al., "Surface plasmon resonance: a versatile technique for biosensor applications." Sensors (Basel). 2015 May 5; 15(5):10481-510. Alternatively, a heparin-associated polypeptide is one that is enriched by a factor of at least 5-fold, 10-fold, 100-fold, or 1,000 from a complex mixture of polypeptides (e.g., a cell supernatant) by the use of heparin bound to a bead or other matrix support, or co-purifies with such a polypetide.

[0080] As used herein "heparin-binding polypeptide" means any polypeptide that directly binds to heparin with a K.sub.D of less than 1 micromolar. Heparin-binding polypeptides can interact with heparin at steady-state under normal growth conditions, but in other instances heparin-binding polypeptides may interact with heparin transiently under normal growth conditions or only under certain conditions as a result of a signaling or environmental stimulus. Heparin binding-polypeptides may interact with heparin as a result of post-translational modifications such as phosphorylation, dephosphorylation, acetylation, deacetylation, lipidation, delipidation, glycosylation, or deglycosylation, or combinations thereof.

[0081] As used herein "pluripotent stem cell" or "pluripotent cell" (PSC) means a cell that has the ability to differentiate into several different cell types that are derivatives of all of the three germinal layers (endoderm, mesoderm, and ectoderm). Pluripotent stem cells are capable of forming teratomas. Examples of pluripotent stem cells are embryonic stem cells (ESCs), embryonic germ stem cells (EGCs), embryonic Carcinoma Cells (ECCs), and induced pluripotent stem cells (iPSCs). PSC may be from any organism of interest, including, primate, human; canine; feline; murine; equine; porcine; avian; camel; bovine; ovine, and so on.

[0082] As used herein "somatic cell" means any cell of an organism that, in the absence of experimental manipulation, does not ordinarily give rise to all types of cells in an organism. In other words, somatic cells are cells that have differentiated sufficiently that they will not naturally generate cells of all three germ layers of the body, i.e., ectoderm, mesoderm and endoderm. For example, somatic cells would include muscle cells and muscle progenitor cells, the latter of which may be able to self-renew and naturally give rise to all or some cell types of the skeletal, cardiac, or smooth muscle but cannot give rise to cells of the ectoderm or endoderm lineages.

[0083] As used herein the term "about" refers to an amount that is near the stated amount by 10% or less.

[0084] As used herein the terms "individual" "subject," and "patient" are interchangeable. The individual can be mammal such as a horse, cow, pig, chicken, goat, rabbit, mouse, rat, dog, or cat. In certain embodiments, the individual is a human person.

[0085] The terms "polypeptide" and "protein" are used interchangeably to refer to a polymer of amino acid residues. Polypeptides, including the provided polypeptide chains and other peptides, e.g., linkers and binding peptides, may include amino acid residues including natural and/or non-natural amino acid residues. The terms also include post-translational modifications of the polypeptide, for example, glycosylation, sialylation, acetylation, phosphorylation, and the like. In some aspects, the polypeptides may contain modifications with respect to a native or natural sequence, as long as the protein maintains the desired activity. These modifications may be deliberate, as through site-directed mutagenesis, or may be accidental, such as through mutations of hosts that produce the proteins, errors due to PCR amplification, or errors in protein translation.

[0086] In some embodiments, a recombinant protein is a protein expressed in a system other than a human, e.g., the protein is expressed from bacteria, yeast, or mammalian cells in culture. In some cases, the protein is expressed from Chinese Hamster Ovary cells (CHO cells). In some cases, the protein is expressed from mouse myeloma cells, e.g., (NS0) cells. In some cases, the protein is expressed from E. coli.

[0087] Percent (%) sequence identity with respect to a reference polypeptide sequence is the percentage of amino acid residues in a candidate sequence that are identical with the amino acid residues in the reference polypeptide sequence, after aligning the sequences and introducing gaps, if necessary, to achieve the maximum percent sequence identity, and not considering any conservative substitutions as part of the sequence identity. Alignment for purposes of determining percent amino acid sequence identity can be achieved in various ways that are known for instance, using publicly available computer software such as BLAST, BLAST-2, ALIGN or Megalign (DNASTAR) software. Appropriate parameters for aligning sequences are able to be determined, including algorithms needed to achieve maximal alignment over the full length of the sequences being compared. For purposes herein, however, % amino acid sequence identity values are generated using the sequence comparison computer program ALIGN-2. The ALIGN-2 sequence comparison computer program was authored by Genentech, Inc., and the source code has been filed with user documentation in the U.S. Copyright Office, Washington D.C., 20559, where it is registered under U.S. Copyright Registration No. TXU510087. The ALIGN-2 program is publicly available from Genentech, Inc., South San Francisco, Calif., or may be compiled from the source code. The ALIGN-2 program should be compiled for use on a UNIX operating system, including digital UNIX V4.0D. All sequence comparison parameters are set by the ALIGN-2 program and do not vary.

[0088] In situations where ALIGN-2 is employed for amino acid sequence comparisons, the % amino acid sequence identity of a given amino acid sequence A to, with, or against a given amino acid sequence B (which can alternatively be phrased as a given amino acid sequence A that has or comprises a certain % amino acid sequence identity to, with, or against a given amino acid sequence B) is calculated as follows: 100 times the fraction X/Y, where X is the number of amino acid residues scored as identical matches by the sequence alignment program ALIGN-2 in that program's alignment of A and B, and where Y is the total number of amino acid residues in B. It will be appreciated that where the length of amino acid sequence A is not equal to the length of amino acid sequence B, the % amino acid sequence identity of A to B will not equal the % amino acid sequence identity of B to A. Unless specifically stated otherwise, all % amino acid sequence identity values used herein are obtained as described in the immediately preceding paragraph using the ALIGN-2 computer program.

[0089] "Exogenous" with respect to a nucleic acid or polynucleotide indicates that the nucleic acid is part of a recombinant nucleic acid construct, or is not in its natural environment. For example, an exogenous nucleic acid can be a sequence from one species introduced into another species, i.e., a heterologous nucleic acid. Typically, such an exogenous nucleic acid is introduced into the other species via a recombinant nucleic acid construct. An exogenous nucleic acid also can be a sequence that is native to an organism and that has been reintroduced into cells of that organism. An exogenous nucleic acid that includes a native sequence can often be distinguished from the naturally occurring sequence by the presence of non-natural sequences linked to the exogenous nucleic acid, e.g., non-native regulatory sequences flanking a native sequence in a recombinant nucleic acid construct. In addition, stably transformed exogenous nucleic acids typically are integrated at positions other than the position where the native sequence is found. The exogenous elements may be added to a construct, for example using genetic recombination. Genetic recombination is the breaking and rejoining of DNA strands to form new molecules of DNA encoding a novel set of genetic information. Often exogenous nucleic acids will include a translatable sequence lacking introns that has been cloned from a cDNA.

[0090] As described herein a "mitogenic polypeptide" is one that induces one or more stages of mitosis, including interphase, prophase, metaphase, anaphase, and telophase. In certain embodiments, a mitogenic polypeptide is one that induces mitosis in any one or more of a soft-tissue cell, a soft-tissue precursor cell, a muscle cell, a muscle precursor cell, or a tenocyte.

[0091] As described herein a "fusion promoting" polypeptide is one that promotes fusion of muscle cells or muscle cell precursors. Fusion of muscle precursors like C2C12 cells is an experimental marker of differentiation and can be monitored by increases in eMyHC or increased number of nuclei per eMyHC positive cell a by a statistically measurable change of at least 25% magnitude (p<0.05) relative to vehicle treated cells grown in otherwise identical conditions.

[0092] In some embodiments, reference to a fusion, fusion polypeptide, or fusion protein refers to a synthetically and/or recombinantly produced molecule in which two or more amino acid sequences are connected, e.g., by a peptide bond and/or linker. In some cases, the two or more amino acid sequences are linked via a linker comprising one or more amino acids. In other cases, the two or more amino acid sequences are not linked via a linker, e.g., the two sequences are directly connected by a peptide bond. In some cases, at least one of the two or more amino acid sequences comprises a polypeptide described herein. For example, the polypeptide described herein is a polypeptide comprising VTN, POSTN, FGF17, THBS2, THBS4, THBS1, IL-15, or IGF2, or a combination thereof.

[0093] In some embodiments, reference to a conjugate, polypeptide conjugate, or protein conjugate refers to a synthetically and/or recombinantly produced molecule comprising a chemical entity covalently bound to one or more amino acids of an amino acid sequence. In some cases, the conjugation is selective such that the chemical entity is connected to a specific amino acid of the amino acid sequence. In some embodiments, the amino acid sequence comprises a polypeptide described herein. For example, the polypeptide described herein is a polypeptide comprising VTN, POSTN, FGF17, THBS2, THBS4, THBS1, IL-15, or IGF2, or a combination thereof.

[0094] In some embodiments, a polypeptide described herein is a proteoform of a protein listed in Table 2. In some embodiments, as used herein a proteoform describes a molecular form of a protein product arising from a gene encoding a protein, such as a protein listed in Table 2. In some cases, a proteoform includes proteins that arise from the same gene as a result of genetic variation, alternatively spliced RNA transcripts, post-translational modifications, or polypeptide cleavage event.

Heparin-Associated Polypeptides

[0095] In one aspect, polypeptides described herein that are useful for treating an aging disease or injury comprise one or more polypeptides secreted from an induced pluripotent stem cell, an embryonic stem cell, a tissue progenitor cell, or a transformed cell line that bind to heparin. In certain embodiments, a plurality of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more heparin-associated polypeptides are included in a composition comprising a pharmaceutically acceptable excipient, carrier, or diluent. In some cases the composition comprises one, two, three, four, five, six, seven, eight, nine, ten or more polypeptides of Table 2. In some cases the composition comprises one, two, three, four, five, six, seven, eight, nine, ten or more polypeptides of Table 1.

[0096] In certain aspects, there are three biochemical features that are common across all potential therapeutic heparin-associated polypeptides: 1) they are secreted by human pluripotent stem cells; 2) they can be purified by heparin agarose beads from a complex mixture, and 3) their molecular weight equals or exceeds 3.5 kDa.

[0097] In certain aspects, there are certain structure-function relationships that potentially link disparate therapeutic polypeptides into a genus of heparin-associated therapeutic polypeptides. Included among these are the ability to be secreted, which may require: 1) an N-terminal signal sequence (aprox. 15-30 amino acids in length); and/or 2) the presence of one or more post translational modifications added in the Endoplasmic Reticulum or the Golgi apparatus to promote stability, such as glycosylation or the presence of disulfide bonds. It is estimated that 2,000 to 3,000 polypeptides encoded by the human genome can be secreted by one or more cell types. In addition to being secretory polypeptides the therapeutic polypeptides may comprise a heparin-binding domain, or, alternatively associate with heparin-binding domain comprising polypeptides. Heparin is a linear polymer of saccharides in 1-4 alpha linkages that form a spiraling chain, commonly associated with its role in binding plasma proteins to reduce clotting (See Capila and Lindhart, "Heparin-protein interactions" Angew Chem Int Ed Engl. 2002 Feb. 1; 41(3):391-412). Currently, predicting heparin-binding from protein sequence alone is a challenge for the field due to the structural heterogeneity of heparin polymers and the large and variable number of shallow binding pockets thought to be important for stabilizing the interaction. Several hundred heparin-associated polypeptides have been empirically tested for heparin binding, using a few heparin chain configurations. Based on these studies many binding motifs have been proposed, but none have been proven necessary and sufficient. One common motif appears to be a sequence of repeating basic residues that orient onto a common surface of the secondary structure for interacting with the matching pattern of sulfate groups on heparin chains. Therefore many heparin-binding therapeutic polypeptides may contain patterns of basic residues (arginine or lysine) clustered in some part of the protein, though agnostic to the exact sequence.

[0098] In certain embodiments, the heparin-associated therapeutic polypeptide is a secreted polypeptide. In certain embodiments, the heparin-associated therapeutic polypeptide is a secreted polypeptide that comprises 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more disulfide bonds. In certain embodiments, the heparin-associated therapeutic polypeptide is a secreted polypeptide that comprises 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or N-liked or O-linked glycans. In certain embodiments, the heparin-associated therapeutic polypeptide is greater than about 3.5 kilodaltons. In other embodiments, the heparin-associated is greater than about 5, 7.5, 10, 15, or 20 kilodaltons. In certain embodiments, the heparin-associated therapeutic polypeptide is one that comprises a region exhibiting enrichment for basic amino acids arginine or lysine. The region can be about 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, or 100 amino acids in length, and comprise an amount of basic residues that is greater than would be 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 100%, 150%, or 200% greater than expected given random chance. In certain embodiments, the heparin-associated therapeutic polypeptide does not comprise a basic DNA binding motif, such as those found in bZIP transcription factors. In a certain embodiment, the heparin-associated polypeptide is heparin binding polypeptide.

[0099] The heparin-associated polypeptides, described herein, can comprise one or more amino acid modifications that promote stability and/or facilitate production. In certain embodiments, the polypeptide can comprise one or more covalent modifications that promote stability (e.g., PEGylation). Other modifications of the heparin-associated polypeptide(s) are contemplated herein. For example, the heparin-associated polypeptide(s) may be linked to one of a variety of non-proteinaceous polymers, e.g., polyethylene glycol, polypropylene glycol, polyoxyalkylenes, or copolymers of polyethylene glycol, polysialic acid, glycolic acid, or polypropylene glycol. In certain embodiments, the heparin-associated polypeptide may be fused or conjugated to another protein to increase stability and or bioavailability. In certain embodiments, the heparin-associated polypeptide may be a fusion with an Fc region of an immunoglobulin or with serum albumin.

[0100] The heparin-associated polypeptides described herein can be encapsulated in nanospheres or nanoparticles to increase stability. In certain embodiments, the nanospheres or nanoparticles are biodegradable or bioabsorbable. Certain types of nanospheres can be deployed such as polylactic acid (PLA), polyglycolic acid (PGA), or Poly(D,L-lactic-coglycolic-acid) (PLGA) microspheres or nanospheres. In certain embodiments, the heparin-associated polypeptide is included in a composition comprising a biodegradable or bioabsorbable carrier that promotes polypeptide stability. In certain embodiments, the biodegradable or bioabsorable carrier comprises polylactic acid (PLA), polyglycolic acid (PGA), or Poly(D,L-lactic-coglycolic-acid) (PLGA). In certain embodiments, the biodegradable or bioabsorable carrier comprises polylactic acid (PLA). In certain embodiments, the biodegradable or bioabsorable carrier comprises polyglycolic acid (PGA). In certain embodiments, the biodegradable or bioabsorable carrier comprises Poly(D,L-lactic-coglycolic-acid) (PLGA).

[0101] In certain embodiments, the heparin-associated-polypeptide may be concatemerized to increase stability and or bioavailability. In certain embodiments, the heparin-associated polypeptide(s) comprises concatemers of the same or of different heparin-associated binding polypeptides. Concatemers can be separated by polypeptide linkers, for example a Gly-Ser linker of any suitable length. In certain embodiments, the Gly-Ser liker comprises a G.sub.4S.sub.1 linker. In certain embodiments, the concatemers comprise 1, 2, 3, 4, 5 or more of the same heparin-associated polypeptide as a single polypeptide separated by a Gly-Ser linker. In certain embodiments, the concatemers comprise 1, 2, 3, 4, 5 or more different heparin-associated polypeptides as a single polypeptide separated by a Gly-Ser linker. In certain embodiments, the concatemers comprise 1, 2, 3, 4, 5 or more of the same heparin-associated polypeptide covalently linked through a non-peptide linkage, such as for example a disulfide bridge. In certain embodiments, the concatemers comprise 1, 2, 3, 4, 5 or more different heparin-associated polypeptides covalently linked through a non-peptide linkage, such as for example a disulfide bridge. In certain embodiments, the concatemers comprise 1, 2, 3, 4, 5 or more of the same heparin-associated polypeptide non-covalently linked, such as for example, by a streptavidin-biotin interaction or protein-protein interaction. In certain embodiments, the concatemers comprise 1, 2, 3, 4, 5 or more different heparin-associated polypeptides non-covalently linked such as for example, by a streptavidin-biotin interaction or protein-protein interaction.

[0102] Additional modifications to heparin-associated polypeptide comprise deletions of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100 amino acids from the N-terminal or C-terminal ends of the heparin-associated polypeptide. In certain embodiments, the heparin-associated polypeptide comprises the deletion of known inhibitory domains or deletion of domains not associated with the heparin-associated-polypeptides functions in inducing proliferation of muscle, connective, or soft-tissue cell precursors.

[0103] The heparin-associated polypeptides herein can comprise cleavage products of a pro-protein. Cleavage of a pro-protein can result in activation or higher activity of said pro-protein. In certain embodiments, heparin-associated polypeptides are produced that correspond to a cleaved or active form of the pro-protein. In certain embodiments, the heparin-associated polypeptides comprise only the active domain of a heparin associated pro-protein (e.g., the minimal portion sufficient to create a biological effect).

[0104] In certain embodiments, the heparin-associated polypeptide comprises one or more of the polypeptides listed in Table 1 and/or Table 2.

EXAMPLES

[0243] The following illustrative examples are representative of embodiments of the compositions and methods described herein and are not meant to be limiting in any way.

Example 1--Isolation of Heparin-Associated Polypeptides

[0244] hESC secretome collection (differentiated vs undifferentiated): Human embryonic or induced pluripotent stem cells (H1, H9, H7 lines, and 2 iPSC lines derived from 1 healthy young adult female (18-25 years) and 1 aged female (greater than 65 year) donor), were cultured in triplicate on 10 cm plates on diluted Matrigel (1:30), in mTeSR-1 (Stem Cell Technologies), for a total media volume of 10 mL per plate. Another triplicate set of hPSCs/iPSCs were cultured on 10 cm plates and differentiated after plating in mTeSR-1 by changing the medium to DMEM/F12 with 10% Bovine Growth Serum (Hyclone), and culturing for an additional 7 days. hPSCs/iPSCs and differentiated hPSCs/iPSCs (6 plates in total) were washed twice with Opti-MEM (Gibco) and then cultured in Opti-MEM for 16 hours. 10 ml media was then collected per plate as hPSCs/iPSCs--secretome or differentiated hPSCs/iPSCs--secretome containing media. Media was spun for 5 min at 1000 g and transferred to new tubes to remove cell debris, aliquoted and flash frozen at 2 mL per plate as 0.5 mL aliquots and stored at -80C; remaining 8 mL/plate was used immediately for heparin-associated protein purification.

Heparin-Associated Protein Purification

[0245] 10 mL of Heparin-Agarose Type I Beads (H 6508, Sigma Aldrich) was washed with molecular grade water and preconditioned in 1 mL OptiMEM as recommended by manufacturer. 8-9 ml secretome containing media was incubated with 1 ml Heparin-Agarose Beads for 2 hours shaking at 4.degree. C. to allow binding. Remaining heparin-depleted hPSCs/iPSCs--conditioned medium or differentiated hPSCs/iPSCs--conditioned medium was aliquoted in 15 mL tubes, flash frozen and stored at -80C to serve as negative controls for efficacy testing. Protein bound heparin beads were washed twice via a 10 minute incubation at 4.degree. C. in 1 mL sterile PBS+0.05% Tween. Proteins were eluted twice for 15 minutes at 4.degree. C. in 400 .mu.l of elution buffer A (Eluted-A) (0.01M HEPES pH 7.5+1.5M NaCl+0.1% BSA) per 10 cm plate for the first two plates, or elution buffer B (Eluted-B) lacking BSA (0.01M HEPES pH 7.5+1.5M NaCl)** for the 3rd 10 cm plate, to collect proteins in a total of 800 .mu.l of elute per original plate. The proteins were desalted by diffusion dialysis (3500 MWCO) (by a 2 hour dialysis shaking at 4C in 500 ml McCoy's 5A Medium or similar tissue culture medium (Gibco) followed by overnight (not more than 16 hours) dialysis shaking at 4C in 200 ml OptiMEM (Gibco). The collected eluate was aliquoted in appropriately capped tubes, flash frozen and stored at -80C.

Secretome Heparin-Associated Fraction Validation Assays:

[0246] BCA assay (Pierce) was performed for total protein yield in the eluate using 2 .mu.l per sample in triplicate according to manufacturer's instructions from each Elution A sample and Elution B.

[0247] SDS-PAGE Silver Stain/SDS-PAGE Coomassie was performed for protein integrity and rough MW analysis (loading <5-10 ug per lane for each sample).

Mouse Myoblast Proliferation Assay

[0248] Reduced regeneration from an individual's tissue progenitor cells is a hallmark of aging, therefore assays that measure mitogenic capacity in tissue progenitor cells serve as a read-out for potential success of any given heparin-associated polypeptide as a regenerative factor. Measuring the increased proliferation rate of treated mouse or human muscle progenitor cells will provide good basis for potentially therapeutic regenerative factors for treating individuals who have suffered illness, injury, or who possess genetic or developmental defects leading to premature tissue loss, wasting, or weakening. As a control, the assay will also be performed on proteins purified from differentiated cells, which result in no in myoblast proliferation, cultured in medium conditioned by differentiated cells, or purified heparin-associated fractions.

[0249] Mouse muscle progenitor cells (early passage myoblasts) were cultured and expanded in mouse growth medium: Ham's F-10 (Gibco), 20% Bovine Growth Serum (Hyclone), 5 ng/mL FGF2 and 1% penicillin-streptomycin on Matrigel coated plates (1:300 matrigel: PBS), at 37.degree. C. and 5% CO2. For experimental conditions, cells were plated at 40,000 cells/well on Matrigel coated 8-well chamber slides in 250-500 uL medium per well (1:100 matrigel: PBS) in mouse fusion medium: DMEM (Gibco)+2% horse serum (Hyclone). One hour after plating, mouse myoblasts were treated with 50% respective medias:

Mouse Myoblasts were cultured for 24 hours in the above conditions, at 37.degree. C. in 10% CO.sub.2 incubator. BrdU (300 .mu.M) in DMSO was added for 2 hours prior to fixation with cold 70% ethanol and stored at 4.degree. C. until staining.

Quantifying Regenerative Index

[0250] Following permeabilization in PBS+0.25% Triton X-100, antigen retrieval was performed via a 10 minute 4 N HCl treatment followed by PBS washes. Primary staining was performed overnight at 4.degree. C. in PBS+2% FBS. Primary antibodies include: a species-specific monoclonal antibody for mouse anti-embryonic Myosin Heavy Chain (eMyHC, hybridoma clone 1.652, Developmental Studies Hybridoma Bank) and Rat-anti-BrdU (Abcam Inc. ab6326). Secondary staining with fluorophore-conjugated, species-specific antibodies (Donkey anti-Rat-488, #712-485-150; Donkey anti-Mouse-488, #715-485-150; all secondary antibodies from Jackson ImmunoResearch) was performed for 1 hour at room temperature at a 1:500 dilution in PBS+2% FBS. Nuclei are visualized by Hoechst staining. For cell quantification, 5 images per well were collected at 20.times. in each of the channels as well as DIC to achieve at least 2000 imaged cells per condition. Using the Hoechst stain to tally cell number, the percent of cells positive for BrdU and eMyHC were tabulated and reported.

[0251] Human muscle progenitor cells (myoblasts) were similarly activated to proliferate when conditioned with hPSC-secreted heparin-associated proteins. Proliferation assays were performed on human myoblasts to test protein candidate factors for enhanced precursor cell activity in an in vitro screening assay. Conditions for culturing human muscle cells were optimized to reflect the slower rate of growth and differentiation of human muscle cells, where early passage human myoblasts were cultured for 72 hours with daily medium changes rather 24 hours, and pulsed for 4 hours with BrdU instead of 2 hours.

Example 2--Characterization of the Protein Components of the Heparin Bead Binding hPSC Secretomes

Protein Quantification

[0252] The protein concentration in the eluted sample was determined using the bicinchoninic acid (BCA) protein assay (Thermo Fisher Scientific, Waltham, Mass.). The protocol was performed as follows: A volume containing 100 ug protein was extracted and disulfide bonds were reduced with 5 mM tris-(2-carboxyethyl)-phosphine (TCEP), at room temperature for 25 min, and alkylated with 10 mM iodoacetamide at room temperature for 30 min in the dark). Excess iodoacetamide was quenched with 15 mM dithiothreitol (room temperature, 15 min in the dark). At this point the sample were split, with 20 .mu.g analyzed immediately via SDS-PAGE Silver Stain, 20 .mu.g saved for SDS-PAGE Coomassie stained gel band analysis, and 60 ug proceeded to in-solution mass spectrometry sample preparation.

Quantify the Size Distribution of Proteins

[0253] Silver staining provides a sensitive, rapid, low cost way to survey the complexity and general molecular weight distribution of the proteins in a complex mixture. By running a matched sample treated to remove glycans, the presence of this PTM common secreted proteins can be determined by the resulting shift in apparent molecular weight. Additional rounds of selective glycosylation reactions can then be run to gain insight into the identity and structure of glycan modifications on proteins of interest. Five micrograms of sample can be removed and treated with Protein Deglycosylation Mix II (NEB) to remove all N-linked and simple O-linked glycans as well as some complex O-linked glycans, which can be visualized by molecular weight shifts relative to an untreated control on a silver stained SDS-PAGE gel.

[0254] A 4-12% acrylamide gel (BioRad) in 1.times. MOPS buffer was loaded gel with samples (>0.20 ug/lane) and ladder (as per manufacturer's instructions), run at 200V for 45 minutes or until sample front neared the bottom of the gel, and incubated in 50% methanol/50% LC grade water >1 hour. Stain solution was prepared adding a solution of 0.8 g AgNO3 in 4 mL LC grade H.sub.2O dropwise into a solution of 1 mL 0.36% NaOH+1.4 mL 14.8M ammonium hydroxide under constant stirring followed by the addition of LC grade water to a final volume of 100 mL. Gel staining proceeded by incubating gel in stain solution for 15 minutes, before washing twice with LC grade water, allowing 5-8 minutes of incubation per wash step. The silver stain was developed by incubation in a solution of 0.25 mL 1% citric acid+25 uL 37% formaldehyde in 50 mL LC grade water for 10-15 minutes in the dark (or until desired density was achieved). Developer solution was removed and the gel washed with LC grade water to slow development for an imaging series, or development was stopped by incubation in a solution of 45% methanol, 10% acetic acid.

In-Solution Mass Spectrometry Sample Preparation

[0255] Methanol-chloroform precipitation was performed prior to protease digestion (a standard trichloroacetic acid-based precipitation protocol would be substituted here if protein yield from the heparin bead eluates are below 25 ug total). In brief, four parts neat methanol was added to each sample and vortexed, one part chloroform was added to the sample and vortexed, and three parts water was added to the sample and vortexed. The sample was centrifuged at 4,000 RPM for 15 min at room temperature and subsequently washed twice with 100% methanol, prior to air-drying. Samples were resuspended in 50 mM HEPES pH 8.5 and digested at room temperature for 12 hrs with LysC protease at a 100:1 protein-to-protease ratio. Trypsin was then added at a 100:1 protein-to-protease ratio and the reaction was incubated 6 hours at 37.degree. C. Peptide concentrations in the digests were measured using the Quantitative Colorometric Peptide assay kit (Pierce). From each sample bug of peptide digestion solution was taken and enzymatic activity quenched with formic acid to a final pH of <2 before de-salting via C-18 Stagetips, using a standard formic acid/acetonitrile buffer system. Stagetips were eluted directly into autosampler vials in a buffer of 70% acetonitrile and 1% formic acid, dried in a vacuum concentrator, and stored at -80C until being resuspended to .about.1 .mu.g/.mu.1 of Buffer A (typically .about.0.2% formic acid, 5% acetonitrile) for mass spectrometry analysis.

SDS-PAGE Coomassie and in-Gel Band Mass Spectrometry Sample Preparation

[0256] A gel based sample preparation pipeline may be employed if the abundance distribution of the sample is heavily skewed, or where only a few species of proteins account for a substantial majority of the molecules in the sample. This size based separation method has been shown to effectively improve depth of proteomic coverage in biochemically purified protein mixtures.

[0257] Briefly, the protocol begins by running >20 ug per lane of sample out on an SDS-PAGE as in the Silver Stain method above, staining and destaining by Coomassie as per manufacturer's instructions, excising sections of the gel containing potentially interesting proteins, and cutting excised gel sections into 1 mm.times.1 mm squares. Ensure gel pieces are at neutral pH by adding 50-100 .mu.l 100 mM Ammonium bicarbonate, let sit for 10 minutes and discard. Wash gel pieces with 100-150 .mu.l 50 mM Ammonium bicarbonate/50% acetonitrile for 10 minutes, vortexing every 5 minutes to dehydrate. Depending on intensity of stain, repeat step 9 until the gel pieces are clear. Discard solution phase and dry samples in speed vac for 5-10 minutes. To digest proteins add 5 pmol sequencing grade trypsin (Promega Corp.) in 50 mM Ammonium bicarbonate and 0.02% Protease Max to each sample and incubate overnight in 37.degree. C. on a shaking heatblock. Spin down samples at 1000 G for 2 minutes, pull off all liquid, and transfer to a glass autosampler vial. Add 40-50 .mu.l 1% formic acid, 66% acetonitrile 33% 100 mM Ammonium bicarbonate and incubate for 10 minutes at 37.degree. C. to increase peptide release from gel. Spin at 10,000 G for 2 minutes to pellet insoluble protein or detergent degradation production. Extract all solution being sure to avoid pellet areas and combine into autosampler vial. Speed vac total combined extracts to dryness and store at -80C until being resuspended to .about.1 .mu.g/.mu.l of Buffer A (typically .about.0.2% formic acid, 5% acetonitrile) for mass spectrometry analysis.

nHPLC-MS2 Instrumentation and Analysis

[0258] Two, 3-hr gradients were collected per sample using an Orbitrap Fusion instrument coupled to a Waters liquid chromatography (LC) pump (Thermo Fisher Scientific). Peptides are fractionated on a 100 .mu.m inner diameter microcapillary column packed with .about.25 cm of Accucore 150 resin (1.2 .mu.m, 150 .ANG., ThermoFisher Scientific). For each analysis, 1 .mu.g per sample was loaded onto the column. Peptides were separated using a 3 hr gradient of 6 to 46% acetonitrile in 0.2% formic acid at a flow rate of .about.400 nL/min. Instrument settings for the Orbitrap fusion were as follows: FTMS1 resolution (120,000), ITMS2 isolation window (0.4 m/z), ITMS2 max ion time (120 ms), ITMS2 AGC (2E4), ITMS2 CID energy (35%), dynamic exclusion window (90 sec). A TOP10 method was used where each FTMS1 scan was used to select up to 10 FTMS2 precursors for interrogation by HCD-MS2 with readout in the orbitrap.

Data Analysis

[0259] Resulting mass spectra were searched using commercially available analysis software (e.g., Byonic) against a human database publicly available from Uniprot which was concatenated with common contaminants and reversed sequences of the human and contaminant proteins as decoys for FDR determination. Searches restricted the precursor ion tolerance to 20 ppm, and product ion tolerance window was set to 0.5 m/z. Searches allowed up to two missed cleavages, including static carbamidomethylation of cysteine residues (+57.021 Da) and variable oxidation of methionine residues (+15.995 Da). Additional variable modifications may be included, particularly glycosylations, based on the results of the gel shift assay following de-glycosylation treatment or the preview search PTM scan. Results were filtered to a 1% FDR at the protein level per sample.

Example 3--In Vitro Screening of Stem Cell Secreted Factors

[0260] A deeper understanding of a given protein factor's contribution to the regenerative effects of the pool of heparin-associated hPSC secretome will be gained by screening against an established panel of assays for cellular age. Assays include measurements of reactive oxygen species (ROS) production or tolerance, cytoplasmically and in the mitochondria, telomerase activity, measurements of proteostasis capacity via lysosomal, autophagy, and proteasomal routes, epigenetic re-patterning, and cellular energy balance (e.g., ATP/ADP and NAD/NADH ratios). Many of these assay leverage the high-throughput automated microscopy described above to make these measurements in a variety of cell types, including fibroblast, endothelial cells, mesenchymal stem cells, and chondrocytes. Collectively these metrics can inform both the pathway and the mechanisms by which the heparin-associated hPSC secretome or its individual components enact their regenerative effects.

[0261] To begin screening and validating potential regenerative protein factors protein coding sequences will be collected from a publicly available source, such as used for the proteomics analysis (e.g., UniProt). The sequence for each of the proteins will be used to construct a DNA sequence encoding the proteins. The sequences are then each cloned into a plasmid vector system tailored for inducible or constitutive high-copy expression (in mammalian or prokaryotic settings). Alternatively such a plasmid vector system may be designed in silico. Such a plasmid can be transformed into a pool of cells where the encoded protein was transiently expressed from the plasmid. Alternatively the gene of interest could be incorporated in the genomes of a pool of cells (e.g. lentiviral transduction for mammalian cells or homologous recombination for S. cerevisiae) to create stable cell lines for recombinant protein production.

[0262] To de-bulk the target factor list and validate recombinant expression for factor production, a viable route would be to express the construct in a human cell line (like 293T-REx), which exploits: 1) that proteins of interest naturally purify themselves during the secretion process; and 2) will be processed in a natural context, potentially preserving important post translational processing steps. T-REx cells will be grown on 10 cm plates to .about.50% confluence in DMEM with 10% Bovine Growth Serum (Hyclone), 2 mM L-glutamine, and 1% Pen-Strep before initiating translation of a target protein of interest for 48 hr. The media would be collected, spun at 2,000 g to purify, and the supernatant used for heparin-associated enrichment of target factors in mouse myoblast regeneration assays.

Machine Learning Classifier

[0263] By combining and statistically comparing the information from the Regenerative index assay, the Panel of Cellular Age Makers, the Proteomics we can create deep feature vectors for each protein factor, the pool of all factors (from each repeat of the assays), and the negative control pool (from each repeat of the assays). Treating the pool of all factors (or known factors such as FGF-2) as True Positives, and the negative control pool (or known non-functional proteins such as BSA) as True Negatives a supervised clustering algorithm can be trained to classify protein factors. Using a standard 10-fold cross validation scheme to assess the relative accuracy, recall, and confusion matrix graphs of the output of various algorithms' outputs (eg, Naive Bayes, Support Vector Machine, Linear Regression, or Random Forest) trained classifier most likely to successfully distinguish proteins with regenerative potential from the set of target factors can be selected. Target factors (or tested combinations) can then be rank ordered by the probability they derive from the regenerative set compared to the null set. A number of the top scoring target factors (or tested combinations) will then be selected for GMP-grade production for in vivo and in vitro validation.

[0264] Based on the complexity of the original heparin-associated fraction of the hPSC secretome and the limits to which individual proteins can recapitulate the activity of the whole pool, we will test combinations of factors as well. In the simplest approach, we would combine the 293T-REx secretome containing media from two or more cell lines each producing a given factor, and test their combined regenerative efficacy across a range of concentrations in an isobologram analysis using the regenerative index from the Myoblast Regeneration assay.

Example 4--In Vivo Testing of Stem Cell Secreted Factors

[0265] There are two main aspects of muscle degeneration with aging, acute loss following trauma and chronic wasting (sarcopenia), and both of them will be tested. As the therapeutic approach to each case is expected to be different two arms for the in vivo validation is envisioned to specifically test each use-case for the factors as therapeutics in humans. The following Acute Injury Model and Sarcopenia/Chronic Administration Model for the most promising proteins emerging from the machine learning classifier can be carried out.

Acute Injury Model

[0266] Animals were kept under standard animal husbandry condition. Animals were fed standard chow, and have ad libitum access to food and water. Temperature were kept at 22.degree. C. and 12 h light/12 h dark cycles. Animals were acclimated prior to study initiation. The experimental design was: C57BL/6J male mice, N=18; Young: 12-13 week old (3-month-old) mice, n=6; Aged: 77-78 week old (18-month-old) mice, n=12. This design was used to test any single factor identified and validated in in vitro assays or complex mixtures of 2 or more factors.

TABLE-US-00007 TABLE 7 Experimental design of acute injury model. Dose (mg/ Blood Tissue No Group n Test kg) Administration collection collection 1 Young, 6 vehicle n/a i.m, q.d; into terminal TA/GA Vehicle injured muscle muscles 2 Aged, 6 vehicle n/a site on day 0, into 25% Vehicle and 2 sucrose; 3 Aged, 6 Test 0.1 Brain, liver, Test factor heart, and factor lung into 4% PFA

[0267] On Day 0, mice were weighed and underwent muscle injury with focal injection of barium chloride (BaCl, 10 .mu.L, 1.2% w/v in saline, Sigma-Aldrich) in the Tibialis anterior (TA; Day 0) of both the right and left hindlegs. Injections of vehicle or factor A (0.1 mg/kg) were co-administered intramuscularly (i.m) following the BaCl into the TA injured hindleg sites, and again 48 hours later on day 2 (i.m.) into the TA injured hindleg sites. Also on day 2, BaCl (Ctx; 10 .mu.L, 1.2% w/v in saline, Sigma-Aldrich) was injected into the Gastrocnemius (GA, Day 2, i.m.) muscles of both right and left hind legs. Injections of vehicle or a factor were sequentially administered (i.m.) following the BaCl into the TA hindleg sites post-injury, and again 48 hours later on day 4 (i.m.) into the GA injured hind leg sites. Bromodeoxyuridine (BrdU) was be administered (100 mg/kg, i.p.) once daily for 3 days, day 2-4, before sacrifice to label proliferating cells.

[0268] On day 5, animals were sacrificed and animal weight recorded followed by collecting 0.5 ml of terminal blood via cardiac puncture which was processed to plasma and stored at 80.degree. C. We then perfused the animal with 1.times.PBS, carefully dissected the skin from the GA/TA muscles of each hind leg and took photos (prior to excision). After excision of exclusively the GA or TA muscle, excised tissue was photographed, weighed, then placed into 25% sucrose in PBS at 4.degree. C. for 4 hr rinsed in 1.times. PBS, immersed in Tissue-TEK OCT and rapidly frozen before storing the muscles tissues frozen at 80.degree. C. Cryosectioning and H&E were performed to ensure muscle injury site was appropriately visualized. A diagram of the time points for these experiments can be seen in FIG. 2A. Muscle tissue composition from new skeletal muscle fibers, fibrotic tissue, and adipose (fat), were measured. Muscle regeneration, as defined as the number of number of new myofibers with centrally located nuclei per millimeter, fibrosis as defined as the area of fibrotic scarring, size of the fibers, as defined as the width and area, adipose tissue, as defined by the amount of fat surrounding the muscle, were measured to assess level of regeneration.

[0269] Young muscle regeneration after acute focal injury had the highest regenerative index (measured as the number of new myofibers with centrally located nuclei per millimeter squared). Aged muscle regeneration following acute injuries performed on average 30-50% less than young muscle regeneration, in part due to the reduction of mitogenic muscle precursor/progenitor cell activity (FIG. 2B). It was predicted that systemic treatment of aged animals, injured animals, animals with genetic diseases causing muscle wasting, or animals injured by radiation or other tissue damaging treatment, the heparin-associated polypeptides, individually or in various combinations, will improve skeletal muscle regeneration by 20-50%, approaching comparable levels to young healthy animals. It was also predicted that the composition of fibrous scar tissue and fat tissue will be reduced to levels comparable to younger animals by treatment with the heparin-associated polypeptides. And indeed, treatment with the heparin-associated polypeptides did improve the skeletal muscle regeneration of sarcopenic mice to level indistinguishable from the young by both the number of new myoblasts and the reduction in fibrous scar tissue (FIG. 2B).

Sarcopenia/Chronic Administration Model

[0270] After arrival, animals will be kept under standard animal husbandry condition. Animals will be fed standard chow, and have ad libitum access to food and water. Temperature will be kept at 22.degree. C. and 12 h light/12 h dark cycles. Animals will be acclimated prior to study initiation, including any in vivo assay acclimation, if necessary. The experimental design was C57BL/6J male mice, N=18; Young: 12-13 week old (3-month-old) mice, n=6; Aged: 77-78 week old (18-month-old) mice, n=12. This design can be used to test any single factor identified and validated in in vitro assays or complex mixtures of 2 or more factors.

TABLE-US-00008 TABLE 8 Design of sarcopenia/chronic administration model. Dose Blood Tissue No Group n Test (mg/kg) Administration In vivo assay collection collection 1 Young, 6 vehicle n/a i.p, q.d; on day 2 sets of: Animal terminal TA/GA Vehicle -8 to +5 weight, grip muscles 2 Aged, 6 vehicle n/a strength, running into 25% Vehicle wheel performance; sucrose; 3 Aged, 6 Test 0.1 horizontal bar Brain, Test factor 1 set of: In liver, factor capacitance heart, and lung into 4% PFA

[0271] On Day -10, mice will have the following in vivo healthspan measurements will be performed over 1 day as a baseline for age-based parameters: Weight, running wheel performance, grip strength, and horizontal bar. Each assay should be run for 4 trials per assay per animal. These healthspan assays will be repeated on day -1. After one day of rest on day -9, mice will begin 1.times. daily injections (0.1 mg/kg) of vehicle or factor A for the remainder of the experiment until sacrifice (days -8 to +5, 13 days of dosing). On day -4, 6 days after dosing begins, mice will undergo a repeat of the healthspan assays. On day 0, 5 days prior to sacrifice, mice will undergo muscle injury with focal injection of cardiotoxin (Ctx; 10 .mu.g, Sigma-Aldrich) in the Tibialis anterior (TA; Day 0) of the right hindleg only. On day 2, the Gastrocnemius (GA; Day 2) muscle of the right hind leg will then receive cardiotoxin (Ctx; 10 Sigma-Aldrich). BrdU will be administered (100 mg/kg, i.p.) once daily for 3 days, day 2-4, before sacrifice. On day +5, prior to take-down, the animals will have an in vivo incapacitance assay run. On day +5, animals will be sacrificed and animal weight recorded. Collect 0.5 ml of blood via cardiac puncture, process to plasma and store plasma samples at 80.degree. C. The animals will then be perfused with 1.times.PBS. Carefully dissect the skin from the GA/TA muscles of each hind leg and take photos (prior to excision). After excision of exclusively the GA or TA muscle, weigh the muscles, then place muscles into 25% sucrose in PBS at 4.degree. C. for 4 hr. Then rinse the muscles in 1.times. PBS, adding Tissue-TEK OCT and storing the muscles tissues frozen at 80.degree. C. Perform cryosectioning and H&E, ensuring muscle injury site is appropriately visualized. Carefully excise the inguinal white adipose tissue (WAT) and weigh tissue. Discard WAT post-weighing.

[0272] Collected brain, liver, heart and lung can be post-fixed in 4% PFA for 72 hours, after 72 hours, transferred into 30% sucrose in 1.times.PBS and stored at -4.degree. C. (brain, liver, heart, lung).

[0273] Muscle tissue composition, from new skeletal muscle fibers, fibrotic tissue, and adipose (fat), will be measured. Muscle regeneration, as defined as the number of number of new myofibers with centrally located nuclei per millimeter, fibrosis, as defined as the area of fibrotic scarring, size of the fibers, as defined as the width and area, adipose tissue, as defined by the amount of fat surrounding the muscle, will be measured to assess level of regeneration. Weights of the animals during the duration of treatment with heparin-associated polypeptide(s), as well as healthspan assays including performance on a running wheel (speed, distance, duration), grip strength, and performance on a horizontal bar will take into account the phenotypic outcomes of treatment of the aged animals systemically with the heparin-associated polypeptides for sarcopenia.

[0274] The horizontal bar test is performed as described previously (Malinowska et al. 2010) at 8 months (n=6 WT, n=7 MPS IIIB) and 10 months (n=3 WT, n=4 MPS IIIB) of age. In brief, a 300-mm metal wire, 2 mm in diameter, was secured between two posts 320 mm above a padded surface. The mouse was allowed to grip the center of the wire and the time to fall or reach the side was recorded, and after 2 min the test was stopped. Crossing the bar in x seconds was scored as 240-x, remaining on the bar was scored as 120, and falling off the bar after y seconds was recorded as the value of y. The test was repeated three times as a practice run followed by a 10-min rest prior to three tests where the score was recorded.

[0275] Young muscle regeneration after acute focal injury has the highest regenerative index (measured as the number of new myofibers with centrally located nuclei per millimeter squared). Aged muscle regeneration following acute injuries performs on average 30-50% less than young muscle regeneration, in part due to the reduction of mitogenic muscle precursor/progenitor cell activity. We predict systemic treatment of aged animals, injured animals, animals with genetic diseases causing muscle wasting, or animals injured by radiation or other tissue damaging treatment, the heparin-associated polypeptides, individually or in various combinations, will improve skeletal muscle regeneration by 20-50%, approaching comparable levels to young healthy animals. We also predict the composition of fibrous scar tissue and fat tissue will be reduced to levels comparable to younger animals by treatment with the heparin-associated polypeptides.

[0276] Animals will also have better healthspan outcomes: reduced weight, fat composition, scar tissue around muscles, increased running speed, duration, and distance, increased grip strength, and enhanced performance on the horizontal bar test.

Example 5--Additional Tests for Pro-Regenerative Factors

[0277] Mechanistic insight into a given heparin-associated polypeptide factor's pathway of action will be gained by establishing and screening against a panel of assays for cellular age. Assays include measurements of reactive oxygen species (ROS) production or tolerance cytoplasmically and in the mitochondria, telomerase activity, measurements of proteostasis capacity via lysosomal, autophagy, and proteasomal routes, epigenetic re-patterning, and cellular energy balance (e.g., ATP/ADP and NAD/NADH ratios). Many of these assay leverage high-throughput automated microscopy to make these measurements in a variety of cell types, including fibroblast, endothelial cells, mesenchymal stem cells, and chondrocytes. Collectively these metrics can inform both the pathway and the mechanisms by which the heparin-associated hPSC secretome or its individual components enact their regenerative effects. These deep profile vectors can be crucial for approaching combinations of factors rationally, and for machine learning predictions.

[0278] To test the cellular effects of secretomes toward reversing the hallmarks of aging, high-throughput automated imaging and quantification of single cells to achieve deep population level statistical power can be employed. Cellular component state profiles of Young, Aged, and Aged+ Treatment in human fibroblasts and epithelial cells, myoblasts, mesenchymal stem cells, chondrocytes, and neural progenitor cells will be compared. Some examples of tests and methods include:

[0279] 1) Epigenetic reprogramming: repressive mark H3K9me3, the heterochromatin-associated protein HP1.gamma., nuclear lamina support protein LAP2a

[0280] 2) Nuclear membrane Folding/Blebbing: immunofluorescence of the nuclear membrane protein Lamin A/C

[0281] 3) Proteolytic Activity: Cleavage of fluorescent-tagged chymotrypsin like substrate corresponds to proteasome 20S core particle activity. Wells are first stained with PrestoBlue Cell Viability dye (Life Technologies) for 10 minutes. Well signals are read using a TECAN fluorescence plate reader as a measure of cell count. Then cells are washed with HBSS/Ca/Mg before switching to original media containing the chymotrypsin like fluorogenic substrate LLVY-R110 (Sigma) which is cleaved by the proteasome 20S core particle. Cells are then incubated at 37.degree. C. in 5% CO2 for 2 hours before signals are again read on the TECAN fluorescence plate reader. Readings are then normalized by PrestoBlue cell count.

[0282] 4) Formation of autophagosomes: Autophagosome number and volume are measured by staining with CellTracker Deep Red (Sigma). The cells are then incubated at 37.degree. C. in 5% CO2 for 20 minutes, washed 2 times using HBSS/Ca/Mg, and stained for 15 minutes using CellTracker Deep Red cell labeling dye. Cells are then switched to HBSS/Ca/Mg for single cell imaging using the Operetta High Content Imaging System (Perkin Elmer).

[0283] 5) Energy Metabolism: ATP in the cells is measured using colorimetric assay using an ATP assay kit (ab83355; Abcam, Cambridge, Mass.) following manufacturer's instructions. Cells are washed in cold phosphate buffered saline and homogenized and centrifuged to collect the supernatant. The samples are loaded with assay buffer in triplicate. ATP reaction mix and background control (50 .mu.L) is added to the wells and incubated for 30 min in dark. The plate is read at OD 570 nm using SpectraMax M2e (Molecular Devices, Sunnyvale, Calif.). The mean optical density is used to estimate of the intracellular ATP concentration relative to the standard curve.

[0284] 6) Mitochondrial Activity: To measure Mitochondria Membrane Potential, cells are washed twice with Ham's F10 (no serum or pen/strep). Subsequently, MuSCs are stained with MitoTracker Green FM (ThermoFisher, M7514) and DAPI for 30 minutes at 37.degree. C., washed three times with Ham's F10, and analyzed using a BD FACSAria III flow cytometer. To measure

[0285] 7) Mitochondrial ROS Measurement. Cells are washed with HBSS/Ca/Mg and then switched to HBSS/Ca/Mg containing MitoSOX (Thermo), a live cell permeant flurogenic dye that is selectively targeted to mitochondria and fluoresces when oxidized by superoxide. Cells are incubated for 10 minutes at 37.degree. C. in 5% CO2. Cells are then washed twice with HBSS/Ca/Mg, and stained for 15 minutes using CellTracker Deep Red. Finally, cells are imaged in fresh HBSS/Ca/Mg using the Operetta High Content Imaging System (Perkin Elmer).

[0286] 8) Deregulated Nutrient Sensing: levels of SIRT1 are measured.

[0287] 9) Senescence: Senescence-associated beta-galactosidase staining is measured in cells washed twice with PBS then fixed with 15% Paraformaldehyde in PBS for 6 minutes. Cells are rinsed 3 times with PBS before staining with X-gal chromogenic substrate, which is cleaved by endogenous Beta galactosidase. Plates are kept in the staining solution, Parafilmed, to prevent from drying out, and incubated overnight at 37.degree. C. with ambient CO2. The next day, cells are washed again with PBS before switching to a 70% glycerol solution for imaging under a Leica brightfield microscope.

[0288] 10) Secretome of the cells: Mass-Spec or 0-Link for inflammatory cytokines profiles

[0289] Soft Tissue Deposition: Immunofluorescence for SOX9, MMP3, MMP13, and COL2A1 expression, the decrease of which is characterized by cartilage loss, pain, cleft-lip, and joint destruction.

Example 6--Identification of Pro-Regenerative Factors by Mass Spectroscopy

[0290] Factors enriched in the secretome of undifferentiated hPSCs can be determined by Mass spectroscopy. A schematic of a type of mass spectroscopy experiment employed herein is shown in FIG. 3A.

[0291] Five confluent, 15 cm plates of cells per biological replicate were washed with OptiMEM--a basal, synthetic medium--, and then incubated in OptiMEM for 16 hours, yielding roughly 100 ml of media. The media, now containing secreted factors, was collected, cells and cell debris removed by centrifugation, and flash frozen for storage at -80C until processing. The target factors were enriched via affinity purification for heparin binding using heparin-agarose bead columns. Heparin-agarose beads (Sigma) were washed with water twice, and once with OptiMEM (minus phenol red), before incubating with factor containing culture media for 2 h at 4.degree. C. shaking at 100 rpm. The ratio of bead slurry (.about.50% beads) to media can be effective at 1:10, 1:20, 1:30, 1:40, and 1:50. Heparin-agarose beads were then collected into a column by centrifugation in an Amicon Pro Purification System column set in a 50 ml conical tube at 1000 g for 5 min, washed with 10.times. column volumes of PBS+0.05% tween at 4.degree. C. twice. Factors were eluted via two repeats of the following: addition of a high salt solution (1.5M NaCl, 0.01M HEPES, pH 7.2, at ratio of 0.4 ml elution buffer per milliliter of bead slurry), incubated at 4.degree. C. for 10 minutes at 100 rpm, and centrifugation at 1000 g for 5 min into a fresh collection tube.

[0292] Protein concentration in the eluted fraction was assayed by silver stain densitometry as shown in FIG. 3B, and a BCA assay against standard curves for bovine serum albumin. Protein disulfide bonds were reduced by incubation in 5 mM tris-(2-carboxyethyl)-phosphine (TCEP) for 25 min, and the free cysteines alkylated with 10 mM iodoacetamide at room temperature for 30 min in the dark. Excess iodoacetamide was quenched with 15 mM dithiotreitol during a 15 min incubation. The eluates from all samples were then further purified by protein precipitation using trichloroacetic acid, prior to resuspending in digest buffer and 16 hr of digestion using a mixture of modified Trypsin and Lys-C to yield peptides predominantly with terminal arginine or lysine residues. The resulting peptide concentration were measured using a quantitative colorimetric peptide assay (Promega), and equimolar amounts of peptides from each biological replicate labeled at their free amines with tandem mass tags (TMT) using manufacturer recommended conditions before mixing the peptides. The mixed sample was desalted via reverse phase separation on a C18 StageTip prior to analysis via nHPLC-SPSMS3 on a Fusion Lumos (Thermo Fisher). A TOP10 method was used to select up to 10 MS2 precursors for identification by CID-MS2 analyzed in the ion trap. For synchronous precursor selection of up to 10 ion windows, the FTMS3 isolation window was 0.4 m/z, max ion time 150 ms, automatic gain control 1.5E5, and FTMS3 resolution was 50,000. Resulting spectra were searched using commercial MS analysis software against the Uniprot human database (2018) protein sequences (Swiss-Prot and TrEMBL) concatenated with their reversed sequences as decoys for FDR determination, appended to common contaminant sequences. Searches restricted the precursor ion tolerance to 50 ppm and the product ion tolerance window to 0.9 m/z (or 50 ppm), allowed no more than two missed cleavages, included static modification of lysine residues, arginine residues and peptide N-termini with TMT tags (+229.163 Da), static carbamidomethylation of cysteine residues (+57.021 Da), and variable oxidation of methionine residues (+15.995 Da).

[0293] Results were filtered to a 1% FDR at the peptide and then protein level using the target-decoy strategy. Peptides were assigned to protein groups, and individual proteins by the parsimony principle. Proteins were quantified by summing reporter ion intensities across all PSMs with greater than 70% of their spectral intensity deriving from matched ions and a summed signal to noise intensity greater than 200, normalizing channel level intensities, and computing the percent contribution of a given channel to the total signal. These values were then used for additional statistical modelling of differential abundance.

[0294] Heparin-associated proteins from undifferentiated and differentiated supernatants generated distinct sets of secreted factors as indicated by FIGS. 3C, 3D and 3E. Combined results from such experiments are summarized in Table 2 shown previously herein, by the gene name, UniProt ID, Entrez Gene ID, and Ensembl ID.

Example 7--Validation of Pro-Regenerative Factors In Vitro Using High-Throughput Imaging

[0295] Mass spectroscopy can define candidate pro-regenerative factors, however, as shown in example 6, these experiments can generate large amounts of data that need to be further validated in relevant in vitro and in vivo models. The use of high-throughput imaging can help define individual factors and mixtures of factors that possess regenerative potential. Mouse muscle progenitor cells can be cultured with BrdU or Edu, in the presence or absence of specific potential pro-regenerative factors, and the degree of proliferation determined using high-throughput microscopy. BrdU or Edu staining indicates proliferation, while embryonic Myosin Heavy-Chain (eMyHC) staining indicates terminal differentiation of the progenitor cells. FIGS. 4A and 4B shows an example of data generated using high-throughput imaging.

[0296] Many of the factors detailed in Table 2 were tested individually for their ability to promote proliferation and/or fusion of mouse muscle progenitor cells in vitro FIG. 5 and FIG. 6.

[0297] The effect of the candidate factors on myogenic activity was assayed in biological triplicate across a range of concentrations centered around expected physiological levels by adding each factor to mouse myoblasts for 48 hours or human myoblasts for 72 hours with daily media changes (DMEM+2% horse serum) and a second pulse of factors. After 24 hours, cells were pulsed for 2-5 hours with EdU (30 uM), ethanol fixed, stained with Hoescht 3342, immunostained for proliferation--as measured by the percent of cells staining positive for EdU (% EdU)--, and immunostained for differentiation--as measured by the increase in cellular area staining positive for embryonic myosin heavy chain (% eMyHC) relative to the negative controls, which received media and vehicle only. Wells were imaged on a Keyence BZ-100 at 4.times., the images quantified in Cell Profiler, and the statistics were computed in R. FIGS. 7A-7B show an example of the proliferation dose response for two of the factors tested. Results for additional factors are summarized below in Table 9.

[0298] The effect of the combination of candidate factors on myogenic activity was assayed in biological triplicate across a range of concentrations centered around expected physiological levels by adding each factor to mouse myoblasts for 48 hours or human myoblasts for 72 hours with daily media changes (DMEM+2% horse serum) and a second pulse of factors. After 24 hours, cells were pulsed for 2-5 hours with EdU (30 uM), ethanol fixed, stained with Hoescht 3342, immunostained for proliferation--as measured by the percent of cells staining positive for EdU (% EdU)--, and immunostained for differentiation--as measured by the increase in cellular area staining positive for embryonic myosin heavy chain (% eMyHC) relative to the negative controls, which received media, individual factors, or vehicle only. Wells were imaged on a Keyence BZ-100 at 4.times., the images quantified in Cell Profiler, and the statistics were computed in R. FIGS. 7C-7M show examples of the proliferation dose response for two or more of the factors tested individually and as a combination to test for synergy. Statistical metrics for increased myogenetic activity from the pair of factors relative to the controls are summarized below in Tables 10-14. Each polypeptide was produced using the method listed in Table 1. Each polypeptide was produced using the method listed in Table 1. The magnitude of the combinations' effects relative to control (FM--negative control, hESC factors--positive control) is shown. The Combination Index (CI) for synergy was calculated using the Highest Single Agent (HAS) model due to the linear dose responses for the individual factor, e.g. FIG. 7B.

Example 8--In Vivo Testing of hPSC Factors Increases Regenerative Index and Reduces Fibrotic Index in an Acute Injury Model in Aged Mice

[0299] FIGS. 9A-9F show that aged mice (18 months) administered isolated, heparin-agarose bead purified hPSC show improved regenerative index and reduced fibrotic index. FIG. 9A shows a schematic of the experiment in this example. This experiment shows that hPSC derived factors can improve histological metrics of muscle health and function. As shown in FIG. 9B heparin-associated polypeptides isolated from human pluripotent stem cells increase regenerative potential and reduce muscle fibrosis in aged mice subjected to a model of acute muscle injury. As shown in FIG. 9C, there was increased muscle regeneration for injured, aged mouse muscle treated with THBS1 (2 ug/mL) compared to young and vehicle-treated, aged mouse muscle.

[0300] FIG. 9D shows the experimental schematic of time-points for dosing and analysis using an acute injury model in aged mice of the effects of individual heparin-associated polypeptides with fusion enhancing effects in vitro. Square denote injury inducing intramuscular injection (IM) with Barium Chloride while circles denote administration of treatment or vehicle. FIG. 9E shows the results of the experiment outlined in FIG. 9D shows that administration of 20 ul of heparin-associated polypeptides PPDGFRL (5 ug/mL, p<3.85E-2) and IGFBP7 (1 ug/mL, p<6.63E-3) resulted in improved new fiber formation (regenerative index compared to vehicle treated aged mice. Stars indicate degree of significance from one-way ANOVA tests. FIG. 9F provides representative images of immunofluorescence staining of sectioned mouse muscle (tibialis anterior) demonstrating increased muscle regeneration for injured, aged mouse muscle treated with POSTN (1 ug/mL) or IGFBP7 (1 ug/mL) compared to vehicle-treated, aged mouse muscle.

[0301] Other models for in vivo testing of hSPC factors include:

Disuse-Reload Injury Model

[0302] This mouse model is a way to observe muscle atrophy in a non-invasive way by contracting the hind limbs of a mouse and preventing extension and flexion, thus reducing the size and strength. The model will serve as an important measurement of muscle regeneration with biologic candidates.

[0303] The hind limb will be immobilized with Cast Tape extended position using sports tape to prevent flexion of the limb. Once the sports tape is in place, a strip of casting tape will be wrapped over the sports tape from the ankle upward, and air dried. The extension of the hind limb should stay rigid in its position of the duration of the study parameters.

[0304] The study begins after mice are acclimated and on Day-3, in which mice from all groups will be weighed. Assigned animals will be given daily i.p. injections of Vehicle control or Candidate Biologic for 3 days before undergoing hind limb immobilization on Day 0 for 7 days with continuous daily i.p. injections. Hind limbs will be observed for any adverse effects due to immobilization. On Day 7 of the study, all animals will be sacrificed and muscle tissue weighed and harvested for further analysis.

Force Measurement

[0305] This study will be used to measure the force of pull in the hind limbs that the animal exerts upon skeletal muscle injury of the tibialis anterior (TA) and gastrocnemius (GA) muscles after injury induction with Barium chloride (BaCl.sub.2). This model will serve to determine which of our biological candidates are efficacious in muscle regeneration.

[0306] Skeletal Muscle Injury Induction: Under anesthesia, BaCl.sub.2 will be administered in two sites on the TA and four sites on the GA (as previously described). Hair will be shaved on the left and right hind limbs prior to injection with small animal hair clippers. On Day 0 of the study, the TA muscle will undergo BaCl.sub.2 induced injury on two sites (previously described). On Day 4 of the study, the GA muscle will follow with BaCl.sub.2 induced injury on four sites. Candidate biologic will be administered on Days 0 and 2 in the injury sites of the TA and GA muscles. BrdU will be injected via IP (QD) on days 4-7 to label proliferating muscle precursor and fibrotic cells in order to measure their regenerative potential.

[0307] On terminal day 7, animals will be deeply anesthetized and a force transducer will be used to measure twitch reactions in the hind limbs of each mouse being tested in the study, via a small incision in the TA to a small metal hook. This will be a terminal procedure. Grip strength measurements: the mice will rest on an angled mesh, facing away from the force meter and with its hind limbs at least one-half of the way down the length of the mesh. The mouse's tail is pulled directly toward the meter and parallel to the mesh. During this procedure, the mouse resists by grasping the mesh with all four limbs. Pulling is continued toward the meter until the hind limbs release.

Ex Vivo Regenerative Measurement

[0308] To confirm these data with age matched, primary muscle stem cells, injury-activated satellite cells associated with myofibers will be isolated from young and old muscle by dissecting the muscle groups of interest and dissociating the tissue to single cell suspensions by incubating in digestion medium (250 U/mL Collagenase type II in DMEM medium, buffered with 30 mM HEPES, pH 7.4) at 37C for 1 hr., triturating the cell suspension, the myofibers were collected by centrifugation and myofibers further digested with 1 U/mL Dispase and 40 U/mL Collagenase type II in 30 mM HEPES at 37C for 1 hr to free muscle stem cells. Muscle stem cells can then be plated and cultured growth media containing serum (2-5%) from the same mouse. The regenerative and fusion potential of the cells will then be assayed as described above in Example 7 and as demonstrated in FIGS. 10B, 10C, 11B, and 11C. This has the advantage of testing the effect of treatment while maintaining the exogenous, often inhibitory extracellular environmental ques contributed by the age appropriate serum.

Example 9--Modelling Treatment of a Muscular Dystrophy with Pro-Regenerative Factors In Vitro Using High-Throughput Imaging

[0309] Muscular dystrophies (MD) encompass a variety of muscular degeneration diseases typically due to genetic mutations in genes encoding proteins responsible for forming and stabilizing skeletal muscle. The phenotypic consequence of these genetic mutations is the progressive loss of muscle mass and strength over time, similar to sarcopenia but with different underlying causes. As heparin-associated polypeptides provided phenotypic improvements on sarcopenic muscle, we tested for similar improvements in a model for MD.

[0310] Many of the factors detailed in Table 2 were tested individually for their ability to promote proliferation and/or fusion of human muscle progenitor cells from a patient with myotonic dystrophy type 1 (hMD)--a muscular dystrophy caused by mutations in the DMPK1 gene.

[0311] The effect of the candidate factors on myogenic activity was assayed in biological triplicate across a range of concentrations centered around expected physiological levels by adding each factor to hMD myoblasts for 72 hours with daily media changes (DMEM+2% horse serum) and a second pulse of factors at the first media change. After 72 hours, cells were pulsed for 2-5 hours with EdU (30 uM), ethanol fixed, stained with Hoescht 3342, immunostained for proliferation--as measured by the percent of cells staining positive for EdU (% EdU)--, and immunostained for differentiation--as measured by the increase in cellular area staining positive for embryonic myosin heavy chain (% eMyHC) relative to the negative controls, which received media and vehicle only. Wells were imaged on a Keyence BZ-100 at 4.times., the images quantified in Cell Profiler, and the statistics were computed in R. FIGS. 12A and 12B show examples of the quantitation of the proliferation response and fusion response for several of the factors tested, respectively. Results those and additional factors are summarized below in Table 15.

Example 10 Assess hPSC Factors In Vivo Using Rodent Models of Becker Muscular Dystrophy for their Ability to Improve Muscle Regeneration and Muscle Mass

[0312] Mdx -/- mice will receive intramuscular injections of the top 3 select hPSC secreted factors selected from the in vitro screen. Indications of enhanced functional regeneration will be assessed through quantification of twitch force measurements and walking track analysis. The Mdx -/- mouse model for BMD is chosen as it has a spontaneous point mutation in the dystrophin gene leading to near complete absence of dystrophin protein. Despite having phenotypic markers of myopathy there are only mild skeletal muscle defects, suggesting that the model best reflects Becker muscular dystrophy. This animal model also mimics the complex paracrine signaling environment, where immune cells and other systemic factors would be involved. Thus, a screen in injured dystrophic muscle for regeneration will efficiently narrow the candidate list for those proteins needed for the ultimate goal of restoring muscle mass and strength to the BMD patients. Myogenesis in a muscle regeneration model will be compared between controls (vehicle-treated) and with the top 3-5 efficacious, dose-optimized factors. Hind limb muscles, the Tibialis anterior (TA) and gastrocnemius (GA) muscle will receive i.m. injection of vehicle control or candidate factor every day for 7 days (t=5 days). BrdU will be also be injected 3 days prior to tissue collection for ex vivo analysis. Muscle regeneration will be assessed in 10 micrometer muscle cryosections. The histological analysis of hematoxylin and eosin staining and immunodetection of eMyHC and BrdU will be used to quantify the numbers of de-novo eMyHC+ myofibers with centrally-located BrdU+ nuclei throughout the injury site. Additionally, myofiber size and muscle weights will also be assessed. For twitch for measurements, mice hindlimbs will be immobilize to a frame. A small incision will be made in the skin directly above the tibialis anterior (TA) muscle to hook to a thin metal hook and then attached to a 300C-LR force transducer (Aurora Scientific). A bipolar electrical stimulation cuff will wrap around the TA and stimulate with a single 0.1-ms pulse for 3 seconds.

[0313] It is expected that administration of select pro-myogenic factors will increase Delta/Notch and MapK signaling, dependent on BMP signaling in Mdx -/- myogenic cells, resulting in increased proliferation, allowing the injury site to heal similar to wildtype muscle--with new muscle fibers--instead of filling with fibrotic scar tissue or adipose tissue as is common in dystrophic muscle. Administration of candidate factors to Mdx -/- injured TA muscle is expected to improve regeneration indicated by quantification of muscle fiber repair and twitch force measurement.
