Characterization of MVs. A Representative TEM images of MVs (scale bars: 1 μm and 200 nm). B Western blot analysis for the expression of EphA2, TSG101 and CD63. C Particle size distribution of MVs measured by DLS. D MVs were observed under a confocal microscope and DOX was shown as a red signal (scale bars: 2 μm)
