Exosomal miR-130a-3p regulates osteogenic differentiation of Human Adipose-Derived stem cells through mediating SIRT7/Wnt/β-catenin axis.

ABSTRACT: OBJECTIVES:It is of profound significance for clinical bone regeneration to clarify the specific molecular mechanism from which we found that osteogenic differentiation of adipose-derived stem cells (ADSCs) will be probably promoted by exosomes. MATERIALS AND METHODS:By means of lentiviral transfection, miR-130a-3p overexpression and knockdown ADSCs were constructed. Alizarin Red S was used to detect the calcium deposits, and qPCR was used to detect osteogenesis-related genes, to verify the effect of miR-130a-3p on the osteogenic differentiation of ADSCs. CCK-8 was used to detect the effect of miR-130a-3p on the proliferation of ADSCs. The target binding between miR-130a-3p and SIRT7 was verified by dual-luciferase reporter gene assay. Furthermore, the role of Wnt signalling pathway in the
