ABSTRACT:
To efficiently select and proliferate the mesenchymal stem cells without necessity of an exclusive separating device and a complicated separating operation, mesenchymal stem cells are cultured by seeding at least one of a bone marrow solution, an umbilical cord blood, a peripheral blood, a synovial membrane and an amniotic membrane in a liquid culture medium which is filled in a vessel, includes water as its main components and having a specific gravity between 1.06 and 1.10 at 37° C., and making a culture at a temperature 37±2° C. on a ceiling side surface of the vessel, preferably the specific gravity being regulated by use of at least one selected from silica fine powder coated by polyvinyl pyrrolidone, a water soluble copolymer of sucrose and epichlorohydrin, and a water soluble compound including a triiodo aromatic ring.
