摘要: 目的 用microRNA-21 inhibitor 转染Flk1+间充质干细胞(MSC),探讨microRNA-21对Flk1+MSC(MSC)迁移的影响。方法 在脂质体介导下用microRNA-21 inhibitor 瞬时转染Flk1+MSC,用Transwell技术检测细胞迁移,用Taqman real-time PCR技术检测micro-RNA的表达。结果 与对照组相比,实验组中microRNA-21表达明显下调,在12、16和20h实验组细胞迁移率分别是对照组的77.5%,71.3%和69.8%。结论 microRNA-21可调控Flk1+MSC的迁移。

Abstract: Objective To evaluate the effect of microRNA-21 on migration of Flk1+ mesenchymal stem cells (MSCs). Methods Flk1+MSCs were transfected with microRNA-21 inhibitor using Lipofectamin2000 and their migratory activity was evaluated by transwell. Taqman real-time PCR was applied to detect expression of microRNA. Results Compared to control group, the expression of microRNA-21 was significantly reduced in the inhibitor-transfected group. Moreover, the number of cells migrated through transwell in the inhibitor-transfected group was 77.5%, 71.3% and 69.8% of that in the control group at 12、16 and 20h , respectively. Conclusion microRNA-21 can regulate the migratory capacity of Flk1+MSCs.
