摘要 探讨流体剪应力对间充质干细胞(MSCs)诱导的内皮细胞抗氧化能力的影响。体外培养大鼠骨髓MSCs,于流室中加载不同强度的流体剪应力,加载后向内皮细胞系诱导,检测所得细胞总抗氧化能力(T-AOC)、一氧化氮(NO)生成量的变化。流体剪应力对MSCs体外诱导所得内皮细胞的总T-AOC、NO均有上调作用,并呈强度依赖关系。流体剪应力对骨髓MSCs体外诱导培养的内皮细胞具有保护性作用,为缺血性心脏病的细胞治疗及心血管组织工程提供了理论基础。 This study examined the effects of flow shear stress on the bio-capacity of the endothelial cells induced from mesenchymal stem cells (MSCs). After cultivating the SD rat mesenchymal stem cells in vitro, we exposed them under different intensity of flow shear stress and induced these cells to endothelial cells. The variations of total anti-oxidation competence(T-AOC) and quantity of nitrogen monoxide(NO) were tested.The results showed that shear stress has an enhanced effect on the T-AOC and NO of endothel...
