Substantially more macrophages (as illustrated by positive staining of macrophage marker F4/80 and MGL) and dendritic cells (as shown by positive staining of DC marker CD11c and MGL) were observed in the tumour surroundings in ME C1galt1-/-/Erb mice (7.2 ± 2.0% F4/80 staining and 6.4 ± 2.0% CD11c staining) than in C1galt1f/f/Erb mice (1.2 ± 0.01% F4/80 staining and 1.3 ± 0.01% CD11c staining) (Fig. 7d). Here, C1GALT1 is linked to neoplasm.
