  In addition to signaling pathways, transcription factors and epigenetic regulators, microRNAs (miRNAs) are emerging as important regulators of human pluripotent stem cells (hPSCs). Pluripotent miRNAs that regulate G1-S transition and pluripotency factors to maintain self-renewal have been identified. However, only 4-5 clusters of miRNAs have been identified in human embryonic stem cells (hESCs). We performed cell cycle phase-based (G1, S, and G2/M phases) miRNA array in pluripotent and differentiated hESCs. We demonstrated that embryonic stem cell-cell cycle (ESCC) regulating miRNAs were all highly expressed in three cell cycle phases of undifferentiated hESCs suggesting a non-cell phase regulated mechanism. From cell phase-dependent miRNAs, G2/M-miRNAs was extracted by principle component analysis (PCA) as a significant component in pluripotent hESCs, whereas G1-miRNAs was a signific.. View More»
