Human Umbilical Cord Mesenchymal Stem Cells Improve the Necrosis and Osteocyte Apoptosis in Glucocorticoid-Induced Osteonecrosis of the Femoral Head Model through Reducing the Macrophage Polarization

The protein expression of AKT, mTOR, p-AKT and p-mTOR was detected using western blot assay. The results showed that human umbilical cord mesenchymal stem cells treatment prominently promoted the glucocorticoid-induced the decrease of the collagen level and the increase of TRAP positive cells.
