Characterization of exosomes secreted by rat endothelial progenitor cells (EPC-Exos). a Morphology of EPC-Exos by transmission electron microscopy. b Particle size distribution of EPC-Exos measured by tunable resistive pulse sensing analysis. c Western blot analysis of exosomal marker proteins (CD9, Alix, TSG101), and negative marker (Calnexin) in EPC-Exos. d EPCs were transfected with miR-control and anti-miR-126 to produce NC-Exos and 126i-Exos. The relative expression level of miR-126 was measured by qRT-PCR. ***P < 0.001 vs Exos and NC-Exos. EPCs endothelial progenitor cells, Exo exosomes secreted by EPCs
