Cell preparation containing mesenchymal stem cells, and method for producing same

摘要

Disclosed is a cell preparation, which contains mesenchymal stem cells that maintain immunosuppressive ability, and which is produced by serum-free or low-serum culture. Specifically disclosed is a method for producing a cell preparation containing mesenchymal stem cells, which is characterized by comprising: a proliferation step wherein mesenchymal stem cells are proliferated in a culture medium that contains FGF, PDGF, TGF-β, HGF, EGF, at least one phospholipid and at least one fatty acid; and a screening step wherein the mesenchymal stem cells after the proliferation step are screened for mesenchymal stem cells in which the immunosuppressive ability is maintained or improved.
