Characterization of thrombin preconditioned WJ-MSCs-derived EVs. (A) Nanoparticle tracking analysis (NTA) evaluated protein concentration and size distribution. (B) EV-specific markers were analyzed using western blot. GM130, negative EV marker (Golgi membrane marker); TGS101, and Flotillin-1 are positive markers of EV surface. Full blot images can be found in Figure S9. GM130, Golgi matrix protein 130; TGS101, Tumor susceptibility gene 101; FLOT-1, Flotillin-1
