CD274 and neoplasm: Moreover, exposure of WT-PD-L1-BT and WT-PD-L1-MDA TNBC cells to PD-1 (Figure 3(B1)), as well as of WT-PD-L1-MCF-7 luminal-A cells (Figure 3(B2)) increased the number of invading cells when they were compared to cells exposed to ctrl; please note that in these experiments of BT and MDA cells (Figure 3(B1)), the cells were plated in the transwells in lower numbers than in the experiments of Figure 3(A1), in order to prevent membrane overloading by tumor cells in the case that PD-1 would increase tumor cell migration.
