摘要: 研究淫羊藿素在GDF-5诱导BMSCs成软骨分化过程中的作用。全骨髓贴壁法分离培养SD大鼠骨髓间充质干细胞(BMSCs),取P3代细胞随机分成4组:对照组,淫羊藿素(Icaritin)组,Growth differentiation factor 5(GDF-5)组,Icaritin+GDF-5联合组。连续诱导培养14 d,倒置相差显微镜观察细胞形态,Alcian Blue染色检测细胞的蛋白聚糖改变,RT-PCR检测软骨分化标记基因Aggrecan、COL2、Sox9及COL1的表达情况,Western Blot检测COL2和COL1蛋白表达水平。结果提示,与对照组及GDF-5组相比,Icaritin+GDF5联合组蛋白聚糖染色更深;软骨分化标记基因Aggrecan、COL2、Sox9明显增加;Ⅱ型胶原蛋白表达量均明显增加。淫羊藿素能够促进GDF-5诱导BMSCs成软骨分化。

Abstract: In this study,the effects of icaritin on chondrogenic differentiation of bone marrow mesenchymal stem cells induced by growth differentiation factor 5 were investigated.BMSCs were collected from Sprague Dawley rats.The morphology was observed by inverted microscope.rBMSCs at passage 3 were randomized divided into 4 groups:control group,Icaritin group,GDF-5 group,Icaritin+GDF-5 group and induced for 14 days.Alcian Blue stain showed the changes of proteoglycans;RT-PCR was used to detect the mRNA expression of Aggrecan,COL2,Sox9 and COL1;the protein expression levels of COL2 and COL1 were detected by Western Blot assay.The results indicated that,compared with the control group and GDF-5 group,Icaritin +GDF-5 group showed deeper proteoglycans staining;cartilage differentiation marker genes Aggrecan,COL2,Sox9 and the protein expression levels of COL2 significantly increased.Icaritin can promote chondrogenic differentiation of bone marrow mesenchymal stem cells induced by GDF-5.

Key words: icaritin, GDF-5, BMSCs, chondrogenic differentiation
