目的:观察bFGF和TGF-β1对原发性骨关节炎( OA)关节软骨间充质祖细胞( MPCs)的促增殖作用,为通过调控关节软骨MPCs以防治原发性OA提供理论依据。方法采用MTT法测定不同浓度bFGF和TGF-β1单独或联合作用下对原发性OA关节软骨MPCs的增殖作用。结果10.0~50.0 ng/mL的bFGF、0.1~1.0 ng/mL的TGF-β1单独作用于传代培养原发性OA关节软骨MPCs时,其培养细胞的增殖速率显著增加(P<0.05),而随着二者浓度的进一步增加,其增殖速率无显著变化(P>0.05);bFGF 10.0 ng/mL+TGF-β11.0 ng/mL联合作用时,对原发性OA关节软骨MPCs具有明显促增殖作用(P<0.05)。结论 bFGF、TGF-β1对原发性OA关节软骨MPCs增殖具有重要作用,不同浓度的bFGF、TGF-β1及bFGF+TGF-β1促增殖作用不同,提示通过适宜浓度的bFGF、TGF-β1对原发性OA关节软骨MPCs的作用,可能具有促进原发性OA关节软骨损伤修复的效果。
目的:觀察bFGF和TGF-β1對原髮性骨關節炎( OA)關節軟骨間充質祖細胞( MPCs)的促增殖作用,為通過調控關節軟骨MPCs以防治原髮性OA提供理論依據。方法採用MTT法測定不同濃度bFGF和TGF-β1單獨或聯閤作用下對原髮性OA關節軟骨MPCs的增殖作用。結果10.0~50.0 ng/mL的bFGF、0.1~1.0 ng/mL的TGF-β1單獨作用于傳代培養原髮性OA關節軟骨MPCs時,其培養細胞的增殖速率顯著增加(P<0.05),而隨著二者濃度的進一步增加,其增殖速率無顯著變化(P>0.05);bFGF 10.0 ng/mL+TGF-β11.0 ng/mL聯閤作用時,對原髮性OA關節軟骨MPCs具有明顯促增殖作用(P<0.05)。結論 bFGF、TGF-β1對原髮性OA關節軟骨MPCs增殖具有重要作用,不同濃度的bFGF、TGF-β1及bFGF+TGF-β1促增殖作用不同,提示通過適宜濃度的bFGF、TGF-β1對原髮性OA關節軟骨MPCs的作用,可能具有促進原髮性OA關節軟骨損傷脩複的效果。

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 (P<0. 05). But with their increased concentration,the proliferation rate was of no significant changes (P>0. 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.
