As shown in Figure 1C, only weakly positive correlations were found between the number of infiltrating CD163+ TAMs and CD66b+ TANs (r = 0.200, P < 0.001) and between CD68+ TAMs and CD66b+ TANs (r = 0.286, P < 0.001), which indicated that CD66b+ TANs may have different contributions to GC progression compared to TAMs. The gene discussed is CD68; the disease is gastric cancer.
