Icariin promotes osteogenic differentiation of bone marrow stromal cells and prevents bone loss in OVX mice via activating autophagy

Osteoporosis (OP) results from the impaired function of endogenous bone marrow mesenchymal stem cells (BMSCs). Icariin (ICA) has shown potential osteoprotective effects. However, the molecular mechanism for the anabolic action of ICA remains largely unknown. The objective of the present study is to investigate whether ICA prevents bone loss by acting on BMSCs via affecting the level of autophagy after ovariectomy (OVX). The BMSCs were extracted...
