Consistently, Hapa1‐6 and CMT93 cells incubated with anti‐CD47 mAb prior to inoculation were further susceptible to macrophage‐mediated phagocytosis in mice treated with anti‐SIRPα mAb inhibiting CD47‐SIRPα “don't eat me” signal, when compared with non‐manipulated those tumor cells, although the differences did not reach the statistical significance (Figure 3). The gene discussed is CD47; the disease is neoplasm.
