The preparation and characterization of BMSC-CMVs and EC-CMVs. a Representative images of DiI labeled hBMSCs and cFDA-SE labeled hUVECs treated with cytochalasin B for 30 min (the scale bar = 50 μm), with insets showing a higher magnification (the scale bar = 20 μm). b Representative CLSM images of BMSC-CMVs and EC-CMVs (the scale bar = 20 μm), with insets showing higher magnification images (the scale bar = 5 μm). c Representative TEM images of BMSC-CMVs and EC-CMVs. Scale bars = 200 nm. d The size distribution of BMSC-CMVs and EC-CMVs. The peaks analyzed by DLS showed that the average sizes of BMSC-CMVs and EC-CMVs were approximately 916.5 nm and 822.3 nm (d, diameter) respectively (n = 3). e The surface ζ-potential of hBMSCs, hUVECs, BMSC-CMVs and EC-CMVs (**P < 0.01, n = 3)
