CD274 and neoplasm: Kinetics and tumor volume analyses demonstrated a more rapid growth of WT-PD-L1-MDA cells than of N35A-PD-L1-MDA cells and N219A-PD-L1-MDA cells; also, mice injected with WT-PD-L1-expressing cells developed larger tumors than mice injected with N35A-PD-L1-MDA cells and N219A-PD-L1-MDA cells (Figure 11B–D).
