Characterization of Exos derived from MSCs. A Cup-shaped morphology of purified Ctrl-Exo and IFN-γ-Exo assessed by TEM. B Representative images of western blot showing the exosomal protein markers in Ctrl-Exo and IFN-γ-Exo groups. C The particle size distribution and particle concentration were analyzed by nanoparticle tracking analysis (n = 3). Confocal images showed that red fluorescence of dye DiI labeled Exos were endocytosed by HUVECs D and H9c2 E 6 and 24 h after incubation. Scale bar = 20 μm
