VEGFA and diabetes mellitus: Finally, in vivo experiments in a mouse model with diabetes and in vitro studies using human umbilical vein endothelial cells (HUVECs) validated that ADSCs enhance the FGFR2 expression and secrete FGF, thereby activating the FGF‐PI3K/Akt‐HIF‐1α‐VEGF signalling cascade, which promotes angiogenesis and facilitates DFU healing.
