Endothelial cells, leading to an inhibition of Notch signaling and an increased capillary-like structure formation

Endothelial cells, leading to an inhibition of Notch signaling and an increased capillary-like structure formation in vitro and in vivo [52]. Therefore, these results indicate that angiogenesis-related proteins and miRNAs may be the main components in exosomes to exert their pro-angiogenesis function. In our experiment, we found that iMSCs-Exo can stimulate angiogenesis-related gene expression and Naramycin A dose protein secretion. After being cultured with iMSCs-Exo, HUVECs expressed higher levels of PGF, HIF-1, TGFB1, VEGFA, VEGFB, Angiogenin, bFGF, KDR, and bFGFR and secreted more VEGF, TGFB1, and Angiogenin. These data indicated that iMSCs-Exo can activate an array of angiogenesis-related gene expression and protein secretion after their uptake by HUVECs. It has been well demonstrated that simultaneous delivery of multiple angiogenic factors is more effective than the delivery of a single angiogenic factor in enhancing vesselHu et al.
