Characterization of EPC-derived exosomes. a Western blot analysis of bovine serum albumin (BSA) expression in fetal bovine serum (FBS) and EPC-derived exosomes. b Western blot analysis of EPC-derived exosomes by CD63 and CD9. c Transmission electron microscope (TEM) images of EPC-derived exosomes. Bar, 250 nm. d Size distribution of EPC-derived exosomes measured by nanoparticle tracking analysis (NTA) peaking at 98 nm. e RT-qPCR result identified the up- and downregulation of miR-126 in exosomes transfected with miR-126 mimics or inhibitor, respectively (n = 3). ***P < 0.001
