Characterization of adipose stem cell- (ASC-) derived extracellular vesicles (EVs). (a) Transmission electron microscopy of ASC-derived EVs showed a spherical shape and lipid bilayers (original magnification ×250,000; the scale bar indicates 200 nm). (b) Average size of the EVs calculated by dynamic light scattering was , and average concentration was particles/ml. (c) Nanoparticle tracking analysis revealed corresponding EV size distribution and a mode of . (d) Western blotting of EVs showed high expression of CD81, CD40, and calnexin.
