Identification of hucMSCs-Exo. A Transmission electron microscopy observation of isolated hucMSCs-Exo; B Western blot detection of hucMSCs-Exo surface markers; C NTA detection of diameter distribution and concentration of extracellular vesicles; D Exo uptake assay observation of hucMSCs-Exo internalization into HRT-8/SVneo cells. All experiments were repeated more than three times
