Identification of MSCs^SC and MSCs^SC-Exos. A Flow cytometry analysis of MSCs^SC markers in P4-ADSCs, the solid red curves represent measured surface markers and the solid blue curves represent isotype controls. B Schematic illustration of MSCs^SC-Exos isolation using differential centrifugation. C Transmission electron microscopy (TEM) analysis for the morphology of MSCs^SC-Exos (Scale bar: 100 nm). D Nanoparticle tracking analysis (NTA) for measuring the size distribution and concentration of MSCs^SC-Exos. E Western blot analysis of protein markers CD9, CD81, Alix, Tsg101, and Calnexin in MSCs^SC-Exos and MSCs^SC
