Extracellular Vesicles from Human Umbilical Cord Mesenchymal Stem Cells Prevent Steroid-Induced Avascular Necrosis of the Femoral Head via the PI3K/AKT Pathway

The effects of human umbilical cord MSC-extracellular vesicles were assessed by measuring the microstructure of the femoral head using HE staining, micro-computed tomography, and TUNEL staining.
