MiRNA-720 regulates stem cell phenotype, proliferation and differentiation of dental pulp cells

ABSTRACT: Small non-coding microRNAs (miRNAs) are known to play crucial roles in stem cell biology, related to cell reprogramming, maintenance of stemness and regulation of cell differentiation. In an attempt to search for novel miRNAs that can control the fate of dental tissue-derived stem cells, we sorted side population (SP) cells, known to be enriched in stem cells, from dental pulp cells (DPCs) and periodontal ligament cells (PDLCs), and performed a miRNA array. As a result, miR-200b and miR-607 were highly expressed in SP cells, whereas miR-1260b and miR-720 was highly expressed in the differentiated main population (MP) cells. Of note, gain-and-loss of function analysis showed that miR-720 regulates the expression of pluripotency factor NANOG and DNA methyltransferases DNMT3A, DNMT3B and DNMT
