| 20080254019 | Therapeutic Agents and Therapeutic Methods For Treating Injured Tissue - This invention provides therapeutic agents, transplants and therapeutic methods that can enhance the regeneration of injured tissue. This invention relates to agents, transplants and therapeutic methods for enhancing the migration and accumulation of mesenchymal stem cells in injured tissues and/or suppressing the diffusion of mesenchymal stem cells from injured tissues. | 10-16-2008 |
| 20090221076 | METHOD OF FABRICATING SHEET FOR CARTILAGE TISSUE REGENERATION - An objective of the present invention is to provide a production method of a sheet for regenerating a cartilage tissue, which uses a conventional sheet-shaped porous body comprising a biological absorbency synthetic high polymer, such as polylactic acid, polyglycolic acid and a copolymer of lactic acid and glycolic acid. The sheet for regenerating the cartilage tissue can differentiate chondrocytes or stem cells without culturing the cells by pressurizing such as a pressurizing culture like the conventional method, and can accumulate the cells in a supporting carrier with high efficiency. The sheet for regenerating the cartilage tissue is produced by the steps of; seeding chondrocytes or stem cells differentiating to the chondrocytes on a sheet-shaped porous body comprising a biological absorbency synthetic high polymer; taking the porous body into a culture liquid; applying acceleration of 100 to 1000 G to the porous body for a predetermined time; and culturing the porous body without applying the acceleration. | 09-03-2009 |
| 20090232773 | Method for Distinguishing Mesenchymal Stem Cell Using Molecular Marker and Use Thereof - Disclosed is a method for distinguishing a mesenchymal stem cell comprising, using at least one gene selected from the genes having the nucleotide sequences indicated by the accession numbers shown in Table 1 as a distinguish marker, detecting the difference in expression of the distinguish marker between a mesenchymal stem cell and a connective tissue cell to distinguish the mesenchymal stem cell from the connective tissue cell. This method enables to distinguish an undifferentiated mesenchymal stem cell from other connective tissue cell such as fibroblasts, osteoblasts, chondrocytes and adipose cells with good accuracy. A mesenchymal stem cell given by this method or a composition comprising the mesenchymal stem sell can be used as a therapeutic for use in the regenerative medicine. | 09-17-2009 |
| 20100158982 | SHEET FOR GUIDING REGENERATION OF MESENCHYMAL TISSUE AND PRODUCTION METHOD THEREOF - To provide a sheet for guiding regeneration of mesenchymal tissue having improved formability, strength, absorbability and efficiency, the sheet is produced by steps of containing a culture medium in a surface of a porous sheet produced by freezing a bioabsorbable polymer material dissolved with an organic solvent and drying it, seeding a mesenchymal cell grown after taking from biotissue, and differentiating the mesenchymal cell to a mesenchymal tissue precursor cell, where the mesenchymal tissue precursor cell and an extracellular substrate are adhered on the surface of the porous sheet containing a culture medium, and the extracellular substrate is secreted in a process of the mesenchymal cell being differentiated to the mesenchymal tissue precursor cell. | 06-24-2010 |
| 20100279412 | CULTURE MEDIUM ADDITIVE FOR USE IN SERUM-FREE CULTURING OF ANIMAL CELL, KIT AND USE THEREOF - Disclosed are: a culture medium containing a specific growth factor and at least one phospholipid; a composition for preparation of the culture medium; a kit; and a method. A technique can be provided which uses a serum-free or low-serum culture medium and has a promoting effect on the proliferation of an animal cell comparable to the promoting effect obtained by the culture in a serum-containing culture medium. | 11-04-2010 |
