Extracellular vesicles derived from endothelial progenitor cells modified by Houshiheisan promote angiogenesis and attenuate cerebral ischemic injury via miR-126/PIK3R2.

ABSTRACT: Angiogenesis following cerebral ischemia is crucial for restoring blood supply to the ischemic region. Extracellular vesicles (EVs) derived from endothelial progenitor cells (EPCs) offer potential therapeutic benefits in the treatment of cerebral ischemia. Houshiheisan (HSHS) has been shown to improve clinical outcomes in ischemic stroke patients, reduce cerebral ischemic damage in rats, and protect endothelial cells. However, the potential effects of HSHS-modified EPC-derived EVs (EVs^HSHS) for cerebral ischemia remain unexplored. This study investigated the impact of EVs^HSHS on angiogenesis using rats with permanent middle cerebral artery occlusion (pMCAO) and brain microvascular endothelial cells (BMECs) subjected to oxygen-glucose deprivation (OGD).
