目的:通过检测>380MHz高频脉冲电磁场刺激下骨髓间充质干细中microRNA-370的表达变化规律,探讨mir-370对骨髓间充质干细胞可能的影响.方法:采用贴壁筛选法分离培养SD大鼠骨髓间充质干细胞,取第3代细胞随机分为两组:电磁场照射组、空白对照组,分别提取总RNA通过Realtime-PCR的结果推测mir-370对大鼠间充质干细胞中的bmp-7的调控作用.结果:经全骨髓细胞贴壁筛选法分离培养的SD大鼠骨髓间充质干细胞符合大鼠骨髓间充质干细胞基本特征.大鼠基因组模板Bmp7已扩增出来,大小与预测一致.在转染克隆有BMP7基因3’UTR质粒的实验组中,mimics组与空白组和NC组相比,(P>0.05)无统计学差异,证明mir-370不能与BMP7基因3’UTR结合,影响萤光素酶的活性.结论:mir-370不能负向调控bmp-7蛋白从而到达抑制骨髓间充质干细胞的作用.

Objective]:> 380MHz high-frequency pulsed electromagnetic fields(HF-PEMFs) stimulation by detecting bone marrow mesenchymal stem cels(BMSCs), microRNAs-370(mir-370) expression variation explore mir-370 on BMSCs may. [Methods]: adherence screening method is isolated and cultured SD rat BMSCs, the 3rd generation cels were randomly divided into two groups: the electromagnetic field radiation group, blank control group, respectively, total RNA was extracted by Realtime-PCR results speculate mir-370 regulation of bmp-7 in rat mesenchymal stem cels. [Results]: adherence screening method of whole bone marrow cels were isolated and cultured in SD rat BMSCs in line with the basic characteristics of rat BMSCs. The rat genome amplified template Bmp7 out, size and forecasts. Clone transfected the BMP7 gene 3'UTR plasmid experimental group Mimics the best choice group compared with the control group and the NC group, (P> 0.05) was not statisticaly different, and that mir-370 can not be combined with BMP7 gene 3'UTR affect the activity of the luciferase. [Conclusion]: mir-370 is not suppression of BMSCs to reach the negative regulation of bmp-7 protein.
