Characterization of MSCs and MSC-Exo. (a) The morphology of MSCs was observed under microscope; scale bar = 200 μm. (b) Flow-cytometric analyses showed that cultured MSCs from rats were positive for CD90 and negative for CD45 and CD11b. (c) The morphology of MSC-Exo was observed under an electron microscope. Bar = 100 nm. (d) The expression of exosome marker CD63 was identified by flow-cytometric analyses. (e) Western blot analysis of CD63 protein in MSC-Exo.
