Characterization of MSC-EVs. A–B Flow cytometry results showed 73.4% and 74.5% of EVs were positive for CD63 A and CD81 (B). C Particle size analysis of the EVs showing the distribution of EVs with different sizes. Around 75% of the particles had the size of exosomes, i.e., 30–200 nm. D Morphologies of two typical EVs taken by transmission electron microscopy (indicated by arrows). E. Western blotting showing the expression of EVs’ markers (CD9, CD63, Hsp70 and ALIX) in two batches of exosomes, EVs-1 and EVs-2, with lower concentration
