Fig. 3From: Homologous tumor cell membrane vesicles active preferential self-recognition of tumor cells in vitroCellular uptake of tumor TCMVs (EV@Panc02, EV@4T1 and EV@ B16F10). The percentage of positive cell (a) and geometric mean fluorescence intensity (b) were analyzed by the flow cytometry. The internalized vesicles into the Panc02 cells were observed by the laser confocal (c) and fluorescence quantify (d) with the softwareBack to article page
