Fig. 4From: 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 geometric mean fluorescence intensity (a) and percentage of positive cell (b) were analyzed by the flow cytometry. The internalized vesicles into the 4T1 cells were observed by the laser confocal (c) and fluorescence quantify (d) with the softwareBack to article page
