Exosomes from Adipose-Derived Stem Cells (ADSCs) Overexpressing miR-21 Promote Vascularization of Endothelial Cells
miR-21 has been indicated to be an important regulator of angiogenesis, involving in regulating the proliferation and migration of vascular cells, like endothelial cells. Direct evidences have shown that downregulation of miR-21 expression signifcantly reduces the proliferation and migration of HUVECs, and conversely, miR-21 overexpression signifcantly enhances HUVECs proliferation and migration, indicating the importance of
