目的 研究在子宫内膜基质细胞( ESC)体外蜕膜化过程中的微小RNA (miRNA)差异表达谱及其细胞周期调控.方法 培养原代ESC,构建ESC体外蜕膜化模型(蜕膜化组),并进行形态学及催乳素水平验证,鉴定其构建成功;以未经蜕膜化处理的ECS作为对照(对照组).采用miRNA微阵列芯片技术筛选两组ESC中miRNA差异表达谱,利用实时荧光定量PCR技术对miRNA微阵列芯片检测结果进行验证.转染miR-222抑制物后,流式细胞仪检测两组体外蜕膜化ESC的细胞周期比例.结果 (1) miRNA微阵列芯片技术筛选结果显示,蜕膜化组与对照组中有49个ESCmiRNA表达水平具有显著差异,其中16个miRNA显著上调,33个miRNA显著下调.实时荧光PCR技术检测显示,hsa-miR-27b、30c、143、101、181b、29b、30d、507、23a、222、221的表达水平在蜕膜化组与对照组比较,差异均有统计学意义(P<0.05).(2)对照组转染阴性对照-6-羧基荧光素(NC-FAM)后S期细胞比例为(6.2±0.7)%,明显低于转染前的(10.9±0.8)%(P<0.05);而G0/G1期细胞[(77.5±1.3)%]较转染前[(73.0±1.6)%]有升高趋势,但差异无统计学意义(P>0.05).蜕膜化组转染后S期细胞比例[(3.3±0.6)%]较转染前[(7.8±0.9)%]明显减少(P<0.05);G0/G1期细胞比例[ (80.7±1.6)%]较转染前[(74.9±1.1)%]有升高趋势,但差异无统计学意义(P>0.05).对照组和蜕膜化组G2/M期细胞比例转染前、后比较,差异均无统计学意义(P均>0.05).结论 miRNA可能通过调控细胞周期进程参与ESC体外蜕膜化过程.
