Characterization of iMSC and sEVs. a Flow cytometric analyses of phenotypic markers of iMSC. iMSCs expressed CD29, CD44, and CD73 and were negative for CD34, CD45, and HLA-DR. b Western blotting analysis indicated that sEVs expressed sEV markers, such as CD9, CD63, and TSG101, and were negative for GM130 and Actin. c Morphology of sEVs under TEM. Scale bar, 200 nm. d Particle size distribution of sEVs measured by NTA
