Morphology and marker analysis of exosomes derived from human primary ADMSCs, BMMSCs, and UCMSCs. (A) Morphology analysis of exosomes observed under TEM showed all exosomes have a cup-shape morphology (Scale bar: 100 nm): (A1) A representative of ADMSC-derived exosomes, (A2) A representative of BMMSC-derived exosomes, (A3) A representative of UCMSC-derived exosomes. (B) Exosomal proteins, 10 μg total protein were loaded each lane, including CD9, CD63, AGO2 and Tubulin, enriched in exosomes released from ADMSCs, BMMSCs, and UCMSCs. ADMSC-EX, ADMSC-derived exosomes; UCMSC-EX, UCMSC-derived exosomes; BMMSC-EX, BMMSC-derived exosomes. Data are representative of at least three independent experiments. Scale bars indicate 100 nm.
