Fig. 3From: Comprehensive insight into endothelial progenitor cell-derived extracellular vesicles as a promising candidate for disease treatmentEVs function as cell communication. Target cells absorb EVs by endocytosis and fusion, while receptors on the membrane can facilitate EVs uptake and regulate cell signal pathway. EVs are characterized by specific markers, such as membrane proteins (CD9, CD63, CD81), major histocompatibility complex (MHC), Alix, TSG101, and HSP70.
