20090117644 | RECOMBINANT HSV USEFUL FOR TREATMENT OF HUMAN GLIOMA - The present invention provides a recombinant HSV having the ability to specifically kill tumor cells such as human glioma cells in vivo, useful and safe for treating human glioma, etc. and that can easily put to clinical use. A new recombinant HSV, KeM345, is constructed by inserting a γ34.5 gene transcription unit, which is expressed by Musashil promoter, into a ribonucleotide reductase gene site of the genome of a herpes simplex virus (HSV) previously attenuated, by means of homologous recombination and obtained as a purified strain. Since KeM345 is a recombinant virus itself, it can not only induce viral proliferation by being transmitted to culture cells but can also induce viral replication equivalent to that of wild-type HSV, showing an excellent cytotoxic effect (cytolytic ability) selectively upon a malignant glioma. | 05-07-2009 |
20090208465 | METHOD OF TREATING NEURAL DEFECTS - The present invention provides a therapeutic agent for a nerve injury and a method for treating a nerve injury. One aspect of the invention is the method for treating a nerve injury by administering to a patient with a nerve injury a therapeutic agent for a nerve injury containing a differentiated cell-derived pluripotent cell obtained by forced expression of reprogramming genes such as a combination of the Oct3/4 gene, Sox2 gene, Klf4, and c-myc gene. in a differentiated cell; or cells obtained by inducing the aforementioned differentiated cell-derived pluripotent cells to differentiate into an embryoid body or a neurosphere. | 08-20-2009 |
20090305320 | Method of detecting activation of notch signal transmission system - The purpose of the present invention is to provide detection methods of Notch signaling activation for detecting the activation of the Notch signaling in living cells simply and conveniently. The expression of a fluorescent protein Venus in a transgenic cell into which a vector having the fluorescent protein Venus gene which is controlled by the wild-type Hes-1 gene promoter has been introduced is compared with the expression of a fluorescent protein Venus in a transgenic cell into which a vector having the fluorescent protein Venus gene controlled by a mutated Hes-1 gene promoter which is not controlled by an activated Notch protein has been introduced, and a transgenic cell in which a signal by the expression of Venus introduced by the vector having the wild-type Hes-1 promoter is observed and in which a signal by the expression of Venus introduced by the vector having the mutated Hes-1 gene promoter which is not controlled by the activated Notch protein is not observed is identified. | 12-10-2009 |
20100081617 | THERAPEUTIC AGENT FOR SPINAL CORD INJURIES - Disclosed is a therapeutic agent effective for the fundamental treatment of a spinal cord injury and a demyelinating disease. Specifically disclosed are a therapeutic agent for a spinal cord injury and a therapeutic agent for a demyelinating disease, each of which comprises an HGF protein as an active ingredient. | 04-01-2010 |
20100120146 | ACTIVATOR OF SIGNAL TRANSDUCTION PATHWAY - The present invention is directed to providing the activator of the integrin signaling in neural stem cells or neural progenitors and the method for using the same. The activator of the integrin signaling comprises galectin-1 and can be used as a regulator that regulates maintenance, survival, or differentiation of a neural stem cells or a neural progenitor. | 05-13-2010 |
20110053183 | METHOD OF CONCENTRATING HUMAN MESENCHYMAL STEM CELLS - The present invention is intended to provide methods for highly enriching human mesenchymal stem cells from a cell population containing the human mesenchymal stem cells. To highly enrich human mesenchymal stem cells, CD271 | 03-03-2011 |
20110055939 | METHOD FOR INTRODUCING FOREIGN GENE INTO EARLY EMBRYO OF PRIMATE ANIMAL AND METHOD FOR PRODUCING TRANSGENIC PRIMATE ANIMAL COMPRISING SUCH METHOD - An object of the present invention is to provide a method for introducing a gene into an embryo for production of a human disease model primate animal using a non-human primate animal such as a marmoset. The present invention relates to a method for introducing a foreign gene into an early embryo of a non-human primate animal, which comprises placing early embryos of a non-human primate in a 0.2 M to 0.3 M sucrose solution, so as to increase the volume of the perivitelline spaces, and then injecting a viral vector containing a human foreign gene operably linked to a promoter into the perivitelline spaces of the early embryos. | 03-03-2011 |
20110183350 | METHOD FOR SELECTING SECONDARY NEUROSPHERE DERIVED FROM DIFFERENTIATED CELL-DERIVED PLURIPOTENT STEM CELL, CLONE SELECTED BY THE METHOD AND USE OF THE CLONE - In order to provide a therapeutic agent for nerve injury which contains iPS-derived neural stem cells and has low or no risk of side effects, as well as a method for treating a nerve injury using the iPS cells, by efficiently establishing in vivo the iPS-derived neural stem having low or no risk of tumor formation, neurospheres are formed following formation of embryoid bodies from the iPS cells, and a clone whose ratio of cells in which the promoter of Nanog gene is activated is 0.01% or less is selected, and the clone is administered to a patient suffering from the nerve injury. | 07-28-2011 |
20110183912 | AGENT FOR PROMOTING NEURONAL DIFFERENTIATION AND METHOD THEREFOR - An agent for promoting neuronal differentiation of a neural stem/progenitor cell includes an inhibitor of function of a COUP-TFI protein and/or a COUP-TFII protein. To promote neuronal differentiation of a neural stem/progenitor cell, the agent is administered to the neural stem/progenitor cell to inhibit function of a COUP-TFI protein and/or a COUP-TFII protein. | 07-28-2011 |
20110250684 | METHOD FOR PRODUCING NEURAL STEM CELLS - In order to provide a method for producing neural stem cells easily and quickly by inducing differentiation of somatic cells directly into neurospheres, dedifferentiation factors are introduced into somatic cells, which are then cultured in suspension in the presence of growth factors to produce the neurospheres, thereby allowing the neural stem cells to be produced quickly without establishing iPS cells. | 10-13-2011 |
