Additionally, when combined with CD47 antibody B6H12, 4 μm PSFL‐NK13 enhanced macrophage phagocytosis of tumor cells in MDA‐MB‐231 and M0 coculture system, compared to B6H12 alone (p < 0.0001 vs control, one‐way ANOVA with Bonferroni post‐hoc test; Figure 8E), making PSFL‐NK13 a promising candidate for therapeutic use. This evidence concerns the gene CD47 and neoplasm.
