CD163 and neoplasm: Upon quantifying infiltrated cells per high power field, while the difference in mean tumor-associated F4/80+ cells between genotypes did not meet statistical significance, there was significant reduction in the density of tumor-associated CD163+ infiltrating cells among lung tumors in Ndst1f/f CD11cCre+ mutant mice (P = 0.02 for difference in means; Fig. 3A, right).
