Exosomes from Human Umbilical Cord Mesenchymal Stem Cells: Identification, Purification, and Biological Characteristics

Figure 1

Characterization of exosomes from hucMSCs. (a) Transmission electron microscopy analysis of extracellular vesicles secreted by hucMSCs. Scale bar: 100 nm. (b) Coomassie Blue staining. The protein extracts of hucMSCs-exosomes were separated by SDS-PAGE. (c) Western blotting analyses of exosomal markers using antibodies against CD9 and CD81.
