摘要:
A cell preparation containing mesenchymal stem cells whose immunosuppression ability is maintained is produced by means of a serum-free or low-serum culture. A method for producing a cell preparation containing mesenchymal stem cells, comprising the steps of: (A) proliferating mesenchymal stem cells in a serum-free medium “A” containing an FGF, a PDGF, a TGF-β, an HGF, an EGF, at least one phospholipid, and at least one fatty acid; and (B) screening mesenchymal stem cells whose immunosuppression ability is maintained or improved, from the mesenchymal stem cells thus proliferated in the step (A).

摘要:
Osteoblast activity is promoted and a large amount of extracellular substrates are produced so as to promote cell proliferation and/or differentiation. A material for repairing biological tissues, the material comprising a biocompatible material containing at least one of niobium and tantalum, is provided. These metal salts are not toxic even at high concentrations, and can activate osteoblasts to increase the production quantity of extracellular substrates. The material for repairing biological tissues is manufactured by mixing a metal salt solution, a calcium compound, and a phosphate compound (S4), then coprecipitating the metal-containing calcium phosphate.

There are provided a body tissue filling material having excellent engraftability and repairability, and a method for producing such a body tissue filling material in a simple manner. Specifically disclosed are: a body tissue filling material comprising a gelatin porous carrier, to the surface of which a coating having sulfated hyaluronic acid is applied; and a method for producing a body tissue filling material, comprising: a step (S3) of adding dropwise a sulfated hyaluronic acid solution to a gelatin porous carrier to effect impregnation thereof; a step (S4) of freezing the porous carrier impregnated with the sulfated hyaluronic acid solution; and a step (S5) of drying the frozen porous carrier.
摘要:
A method of producing a biological tissue-reinforcing material, which is applicable to a site required to be reinforced and which enables to improve the working properties for transplantation, comprising the step S1 of coprecipitating ammonium hydrogen phosphate with calcium nitrate in the presence of sulfuric acid.
