INTRODUCTION
In this study, we aimed to investigate the role of miRNA-21 and the regulating pathway that promotes the differentiation of bone marrow mesenchymal stem cells (BMSCs).
METHODS
We used miR-21-OE, miR-21-KD, ajuba-OE and ajuba-KD plasmids to infect BMSCs. The expression of miRNA-21, ajuba, Isl1 and cTnI was detected by RT-qPCR, WB and immunofluorescence staining in groups.
RESULTS
MiRNA-21 over-expression increased the expression of Isl1, and vice versa. Ajuba over-expression decreased the expression of Isl1, and vice versa. Ajuba negatively regulated the differentiation of BMSCs into cardiomyocyte-like cells.
CONCLUSIONS
MiRNA-21 could regulate differentiation of bone marrow mesenchymal stem cells (BMSCs) to cardiomyocyte-like cells through the ajuba/Isl1 axis pathway.
引言
在本研究中，我们旨在探究miRNA-21的作用以及促进骨髓间充质干细胞（BMSCs）分化的调控途径。
方法
我们使用miR-21-OE、miR-21-KD、ajuba-OE和ajuba-KD质粒感染BMSCs。通过RT-qPCR、WB和免疫荧光染色检测各组中miRNA-21、ajuba、Isl1和cTnI的表达。
结果
miRNA-21过表达增加了Isl1的表达，反之亦然。ajuba过表达降低了Isl1的表达，反之亦然。ajuba负向调控BMSCs向心肌样细胞的分化。
结论
miRNA-21可通过ajuba/Isl1轴途径调节骨髓间充质干细胞（BMSCs）向心肌样细胞的分化。
