Exosomal miR-185 derived from VSMCs attenuates re-endothelialization in balloon-injured rat carotid arteries. (A) Representative images of Evan’s blue staining of carotid arteries from rats treated with exosomes derived from miR-185 mimic transfected VSMCs at day 7 after balloon injury. The percent area of re-endothelialization was quantified as white-area/total-area ratio. (B) Immunofluorescence staining for CD31 in the sections at 1 week after injury. The relative fluorescence intensity is shown. *P < 0.05 vs. NC-Exo.
