ABSTRACT
Objective To observe the regulatory effect of bFGF and TGF-β1 for the proliferation of mesenchymal progenitor cells ( MPCs) derived from primary osteoarthritis cartilage, and to provide theoretical evidence in preventing and curing primary OA. Methods Different concentrations of bFGF and TGF-β1 ( alone or combined) were used to treat primary OA cartilage and their effects on proliferation of MPCs were tested by MTT method. Results Either bFGF (10. 0~50. 0 ng/mL) or TGF-β1 (0. 1 ~1. 0 ng/mL) alone can significantly promote the proliferation of MPCs derived from primary OA cartilage (P0. 05). The combination of 10. 0 ng/mL bFGF and 1. 0 ng/mL TGF-β1 significantly increased the prolifer-ation of MPCs from primary OA (P<0. 05). Conclusion Both bFGF and TGF-β11 play important roles in the proliferation of MPCs in primary OA cartilage,and they can increase the proliferation in different degree with different concentrations. There must be feasible methods of gene technology to promote cell proliferation and differentiation of MPCs for repairing articular car-tilage injury.
