摘要
目的:探讨MC3T3-E1细胞在流体剪切力作用下LEF-1的表达。方法:通过流体剪切加载系统对MC3T3-E1爬片细胞施加12dyn/cm的流体剪切力,分别作用0h,2h,4h,8h,12h,用RT-PCR方法检测细胞受力前后LEF-1 mRNA表达的变化;应用免疫荧光双标记法检测不同时间点流体剪切力作用下MC3T3-E1细胞中的LEF-1 mRNA表达改变。结果:RT-PCR和免疫荧光双标记法的结果表明12dyn/cm 8h流体剪切力作用下的MC3T3-E1细胞LEF-1 mRNA的表达较其它各组明显增强。结论:通过流体剪切力力学刺激,激活了成骨细胞LEF-1/TCF1转录活动,LEF-1 mRNA的表达增强可能是成骨细胞经典Wnt信号通路对剪切应力的应答反应。
