Characterization of the hNSC-derived exosomes. (a) Scanning electron microscopy image of exosomes. Scale bar: 200 nm. (b) Transmission electron microscopy image of exosomes that show nanoscale of exosomes. Scale bar: 100 nm. (c) The size and size distribution of purified exosomes which derived from hNSCs were measured by nanoparticle tracking analysis. The mean number and polydispersity index hNSC-derived exosomes were 101.49 nm and 0.43, respectively.
