Tumor-associated neutrophils are dramatically reduced by tomato concentrate containing the 6F peptide (Tg6F), but not control tomato concentrate (EV) in a mouse model of colon cancer cells metastasizing to the lungs. Tumor-associated neutrophils in the lungs of the mice described in Figure3 were determined as described in Materials and Methods. (A) Representative examples from each treatment group. (B) The % area stained for Ly6G (mean ± SEM). NS, not significant. The experiment was done once.
