Characterization of EVs from hP-MSCs. (a) Representative transmission electron microscopy (TEM) image of isolated EVs. Scale bar, 50 nm. (b) The diameter of EVs was around 130 nm as showed by Nanoparticle Tracking Analysis (NTA). (c) Western blot results showed the expression of CD9 and CD63 in EVs and hP-MSCs. (d) The uptake of EVs (red) by HCEs. Scale bar, 50 μm.
