ABSTRACT
Objective To observe the effect of Sox9 gene overexpressian on chondrogenesis of esenchymal stem ceils (MSCs) in vitro. Methods Rabbit MSCs were obtained and purified by gradient centrifuge and adhesion culture in vitro. MSCs were transfected by recombinant Sox9 plasmid. RT-PCR and Western blot analysis were used for transfection confirmation. Chondrogenic molecules such as type I1 collagen,aggrecan and Sox9 were detected by immunohistology, RT-PCR and western blot. Cell proliferation was tested by MTT assay. Results MSCs were successfully transfected with Sox9 gene and verified by RT-PCR and Western blot analysis. The overexpression of Sox9 had no effect on the proliferation of MSCs. Transfeeted cells expressed more chondrogenic markers than the control groups. Conclusion Sox9 gene overexpression can enhance chondrogenic differentiation of MSCs.
