Characterization of ESCs and ESC-derived exosomes. a ESC colonies morphology. Scale bar, 100 μm. b ALP staining of ESCs. Scale bar, 100 μm. c IF staining analysis of pluripotency-related markers of ESCs. Scale bar, 50 μm. d Particle size distribution of ESC-Exos measured by qNano analysis. e Morphology of ESC-Exos observed by TEM. Scale bar, 100 nm. f Western blotting showed the presence of exosomal markers including CD9, CD63, and TSG101, but exosomes were negative for GM130, Actin, and Lamin A/C
