Extracellular Vesicles from Hypoxia-Preconditioned Microglia Promote Angiogenesis and Repress Apoptosis in Stroke Mice via the TGF-β/Smad2/3 Pathway

By exposing bEnd.3 endothelial cells and primary cortical neurons to oxygen−glucose deprivation (OGD), the impact of extracellular vesicles from OGD-preconditioned microglia on angiogenesis and neuronal apoptosis by the tube formation assay and TUNEL staining was assessed.
