    摘要： Provided is a differentiation-inducing culture medium additive for inducing bone differentiation of at least one type of cell selected from the group consisting of a stem cell, a dental pulp cell, a periodontal ligament cell, a placenta, an amnion, and a fibroblast under a serum-free condition, and a use of the differentiation-inducing culture medium additive. The differentiation-inducing culture medium additive of the present invention for inducing differentiation of a stem cell under a serum-free condition at least contains at least one growth factor selected from the group consisting of EGF, FGF, and PDGF; dexamethasone; and β-glycerophosphate. The differentiation-inducing culture medium additive of the present invention does not require ascorbic acid 2-phosphate and ITS, which are normally essential for bone differentiation. Further, bone differentiation can be promoted by adding phospholipid.

    摘要： 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.
