20090186412 | POROUS CELL SCAFFOLD AND PRODUCTION METHOD THEREOF - For easily seeding cells in its scaffold, a porous cell scaffold is produced by steps of filling a guiding solution with kinematic viscosity being 50 to 450% of that of a culture medium, in a whole continuous small hole structure having hole diameters of 5 to 3200 μm and an average hole diameter of 50 to 1500 μm, of a sheet-shaped or block-shaped scaffold having a thickness of 2 mm or more, supplying thereafter a culture medium with cells being suspended to an upper side of the scaffold, sucking the guiding solution from a lower side of the scaffold by low suction force, and entering thereby the culture medium with cells being suspended into the whole small hole structure, where a water absorber such as a filter paper is preferably used for sucking the guiding solution by low suction force. | 07-23-2009 |
20090246873 | SCAFFOLD FOR TISSUE ENGINEERING AND PRODUCTION METHOD THEREOF - To provide a scaffold for tissue engineering which consists of a bioabsorbable polymer material to be absorbed in a biotissue, and holds strength of the whole scaffold while having a porosity proper for culturing cells inside thereof as well, a method for producing the scaffold for tissue engineering includes steps of dissolving a bioabsorbable polymer material with an organic solvent, drying the solution so as to produce a porous bioabsorbable polymer material having a porosity of 50 to 99%, covering the porous bioabsorbable polymer material with a bioabsorbable polymer material having a thickness of 0.01 to 5 mm, pores of 10 to 3000 μm diameter, a fracture strength of 0.05 to 0.15 MPa, and a volume of 15 to 90% with respect to the whole scaffold. | 10-01-2009 |
20090261492 | BLOCK-SHAPED SCAFFOLD FOR TISSUE ENGINEERING AND PRODUCTION METHOD THEREOF - A block-shaped scaffold for a tissue engineering with improved shape stability and less volume change in water is produce by the steps of approximate-uniformly mixing the particle-shaped material having 100 to 2000 μm diameter with a solution, where a biodegradable polymer is dissolved with an organic solvent, freezing, drying it to remove the solvent, pulverizing thus obtained intermediate product, dissolving it with a liquid, where the biodegradable polymer is not dissolved, to remove the particle-shaped material taking thus obtained intermediate product into a mold, and pressing and heating it, the scaffold having ununiform and continuous holes occupying 20 to 80% in a cross-section area in a three-dimensional network structure having a small hole structure with 5 to 50 μm diameter, elastic coefficient being 0.1 to 2.5 MPa, and volume change being 95 to 105% when dipping it in water for 24 hours. | 10-22-2009 |
20140341859 | METHOD FOR TREATMENT OF DAMAGED SITE OF BONE - Provided is a treatment method which enables regeneration of bone tissue even when the size of a damaged site of bone is large. The treatment method comprises the steps of: culturing chondrocytes which have been seeded onto a porous body, or differentiating stem cells having chondrogenic differentiation potential which have been seeded onto a porous body into chondrocytes and culturing the chondrocytes; and implanting the porous body having the cultured chondrocytes. | 11-20-2014 |
20140371748 | FRACTURE TREATMENT DEVICE - Provided is a fracture treatment device enabling efficient bone regeneration. The fracture treatment device ( | 12-18-2014 |
20150142128 | TISSUE REGENERATION CONSTRUCT AND METHOD FOR PRODUCING TISSUE REGENERATION CONSTRUCT - Provided is a tissue regeneration construct having a good engraftment property and capable of promoting a stable and favorable regeneration to a target site, the tissue regeneration construct being a member to be applied to a target site for transplantation and regeneration to regenerate tissue, including a transplant body, and an engraftment layer arranged overlapping at least a part of an outer surface of the transplant body, wherein: the transplant body includes a support, cells for regenerating the tissue that are arranged at least either one of a space between the supports and a space formed by a pore inside the support, and a base material for retaining the cells; the base material of the engraftment layer is gelatinous; and the engraftment layer is a layer in which the support does not exist. | 05-21-2015 |
20160113970 | PERIODONTAL TISSUE REGENERATION MATERIAL - It is a problem of the present invention to provide a convenient and safe periodontal tissue regeneration material and provide a method of regenerating a periodontal tissue. The present invention provides a periodontal tissue regeneration material comprising dedifferentiated fat cells (DFAT) as the convenient and safe periodontal tissue regeneration material. The present invention provides a method of regenerating a periodontal tissue with the periodontal tissue regeneration material. | 04-28-2016 |
