Characterization of hucMSC-Ex. (a) CD63 and TSG101 protein expression in hucMSC-Ex were measured with western blot. (b) Exosomes from the culture medium of hucMSCs were observed by transmission electron microscopic (TEM). The scale bar represents 100 nm. (c) Nanoparticle tracking analysis (NTA) data exhibited the average diameter and particle number of hucMSC-Ex.
