Promotion Effects of miR-375 on the Osteogenic Differentiation of Human Adipose-Derived Mesenchymal Stem Cells.

ABSTRACT: MicroRNA plays an important role in bone tissue engineering; however, its role and function in osteogenic differentiation warrant further investigation. In this study, we demonstrated that miR-375 was upregulated during the osteogenic differentiation of human adipose-derived mesenchymal stem cells (hASCs). Overexpression of miR-375 significantly enhanced hASCs osteogenesis both in vitro and in vivo, while knockdown of miR-375 inhibited the osteogenic differentiation of hASCs. Mechanistically, microarray analysis revealed DEPTOR as a target of miR-375 in hASCs. Knockdown of DEPTOR accelerated the osteogenic differentiation of hASCs by inhibiting AKT signaling, which mimics miR-375 overexpression. Furthermore, we confirmed that miR-375 regulated osteogenesis by targeting YAP1, and that YAP1
