Morphology and characterization of HUVECs and cellular uptake of hucMSC-exosomes by HUVECs. a HUVECs cultured for 3 passages exhibited the typical cobblestone morphology of ECs. Bar, 200 μm. b HUVECs were identified by immunofluorescence staining for vWF (green). Nuclei were stained blue with DAPI. Bar, 50 μm. c HUVECs were identified by immunofluorescence staining for CD31 (red). Nuclei were stained blue with DAPI. Bar, 50 μm. d Cellular internalization of hucMSC-exosomes into HUVECs. DiI-labelled hucMSC-exosomes (red) were internalized into DAPI-labelled HUVECs (blue). Bar, 20 μm
