    • 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.
    • 为了有效地选择和增殖间充质干细胞而不需要专门的分离装置和复杂的分离操作,通过种植骨髓溶液,脐带血,外周血,滑膜中的至少一种来培养间充质干细胞 和填充在容器中的液体培养基中的羊膜包含水作为主要成分,在37℃下的比重为1.06〜1.10,培养温度为37±2℃。 在容器的顶棚侧表面上,优选使用选自由聚乙烯吡咯烷酮涂覆的二氧化硅细粉末,蔗糖和表氯醇的水溶性共聚物和包含三碘芳环的水溶性化合物中的至少一种来调节比重 。
