Characterization of EVs. (a) Transmission electron microscopy (TEM) of EVs from human proximal tubule cell supernatant. (b) TEM of EVs from mesangial cell supernatant. (c) TEM of urinary EVs. The scale bar represents 100 nm. (d) Western blot of EVs using the EV protein marker CD63. Lane 1: EVs from human proximal tubule cell supernatant; lane 2: EVs from mesangial cell supernatant; and lane 3: EVs from urine.
