摘要：背景:羌活鱼经大量的临床观察和报道有促进骨折愈合的作用,其具体的作用机制及其有效成分的研究报道尚少。目的:分析羌活鱼研粉物、水提及酸提物含药血清对体外培养骨髓间充质干细胞增殖与成骨性分化的影响。方法:制备羌活鱼研粉、水提物、酸提物,分别采用高、中、低剂量灌服大鼠制得羌活鱼研粉物、水提及酸提物含药血清,以灌服等体积生理盐水制得对照血清;采用贴壁筛选法培养大鼠骨髓间充质干细胞,通过MTT法检测细胞增殖;于干预后的不同时间点分别测定细胞碱性磷酸酶活性、钙盐沉积量、成骨性分化基因表达以及钙化结节数、并比较各组间差异。结果与结论:羌活鱼研粉物及水提物含药血清具有刺激骨髓间充质干细胞增殖活性及促进其成骨性分化的能力,其中尤其以研粉物中剂量组最为明显,而酸提物含药血清并无此功效。主要表现在细胞增殖、碱性磷酸酶活性、钙盐沉积量、成骨性分化基因和钙化结节数显著高于空白对照组(P<0.05)。
BACKGROUND：Bing＇s giant salamander can promote fracture healing,but the mechanism and active ingredients are rarely reported.OBJECTIVE：To investigate the effect of Bing＇s giant salamander containing serum on the proliferation and osteogenic differentiation of rat bone marrow mesenchymal stem cells（BMSCs）.METHODS：Rats were given Bing＇s giant salamander by high,moderate and low doses and their serum were obtained after 7 days.The control serum was obtained by giving equal volume physiological saline.Rat BMSCs were obtained from Wistar rats and screened by the adhesive method.The serum was supplemented into the culture medium of rat BMSCs by different concentration.The proliferation of rat BMSCs was analyzed by MTT assay.The osteogenic differentiation markers including Osterix expression,alkaline phosphatase（ALP） activity,calcium deposition and mineralized bone modulus were compared among the exposed groups and the control at different time point.RESULTS AND CONCLUSION：Moderate Bing＇s giant salamander containing serum showed a stronger stimulation of cell proliferation and significantly enhanced the osteogenic differentiation of rat MSCs,indicated by significantly improving ALP activity,calcium deposition,OSX expression and the number of mineralized bone nodules compared to the control and other groups（P 0.05）.
