The expression of miR-200b in the plasma-derived exosomes. Exosomes were isolated from the plasma of healthy women and EOC patients. a TEM was used to observe the morphology of exosomes. b NTA was used to analyze the size and concentration of exosomes. c The markers of exosomes, including LAMP-1 and TSG101, were detected by western blot. d qRT-PCR was carried out to measure the level of miR-200b in exosomes. *P < 0.05 compared with Health women
