Isolation and identification of USC-Exo. A The morphology and size of isolated USC-derived particles were checked by TEM. Scale bar: 500 nm. B Nanoparticle tracking analysis of USC-derived particles. C USC-Exo were stained with surface antigens antibodies CD9, CD63, and CD81 and analyzed by flow cytometry. D The protein expressions of CD9, CD63, TSG101, Cytochrome C, Calnexin, and Syntaxin 6 in USC-Exo were assessed by western blot analysis. The above data were all measurement data, and all experiment was performed three times
