Exosomal miR-125b-5p Derived from Adipose-Derived Mesenchymal Stem Cells Enhance Diabetic Hindlimb Ischemia Repair via Targeting Alkaline Ceramidase 2

Exosomes were isolated from adipose-derived MSCs culture supernatants by differential ultracentrifugation and their effect on C2C12 cells and HUVECs was assessed by EdU, Transwell, and in vitro tube formation assays separately.
