Characterization of BM-MSC and NPC-derived exosomes by TEM. a PBS used as a control group; b exosomes derived from BM-MSCs; c exosomes derived from NPCs. Exosomes were stained with phosphotungstic acid and observed by TEM (×100,000). The two kinds of exosomes were roughly identical, ranging from 30 to 100 nm. Scale bar = 200 nm.
