Regulatory Role of miRNAs in Human Induced Pluripotent Stem Cells Differentiation
人类诱导性多功能干细胞(hiPSCs)具有分化成所有体细胞的潜能。研究发现小分子RNA(miRNA)与hiPSCs的分化具有极大相关性。然而,miRNAs是否是胚层形成和细胞系分化的关键尚不明确。因此,为了阐明miRNAs在hiPSCs分化中的作用,我将hiPSCs诱导成三个胚层及其代表细胞系,分别是内胚层以及肝细胞,中胚层以及肾干细胞,外胚层以及神经干细胞。通过采集分化过程中不同时间点样本的RNA,我们对三个胚层及其代表细胞系进行了RNA表达谱分析和比较。我们利用生物信息学方法成功预测了细胞系特异性miRNAs的下游靶基因和发育相关基因的上游调控miRNAs。其中,肝细胞特异性miR-192...
