Objective: To examine the property and proliferation ability of primary culturing MSC, investgate the effect of lightly centrifugation and chemical definition medium to induce MSC differentiate into chondroblast.

目的：了解骨髓基质干细胞原代培养的特性及增殖能力，探讨轻度离心和化学限定培养基法诱导骨髓基质干细胞向成软骨方向分化的作用；为软骨组织工程提供足量、合适的种子细胞。

MSC can be obtained by percoll fluid and density gradient centrifugation, this cells kept proliferation and differentiation ability in vitro; MSC can differentiate into chondroblast by lightly centrifugation and chemical definition medium, after one generation, the differential cells kept the phentype of chondroblast, they are a kind of ideal seed-cells for cartilage tissue engineering.

经percoll液密度梯度离心法能获得纯度较高的人骨髓间充质干细胞，这种细胞在体外培养体系中保持旺盛的增殖能力；经轻度离心和化学限定培养基法可诱导骨髓间充质干细胞向成软骨方向分化，增殖旺盛，可传一代培养，是软骨组织工程理想的种子细胞。
