Figure 4. Effect of the CLA and VSL#3 treatment on colon histopathology on experimental Helicobacter typhlonius-induced colorectal cancer.

Figure 4

Bacterial-free 129/SvEv and IL-10 gene deficient (IL-10−/−) 129/SvEv mice in a 129/SvEv background (n = 60) were treated with the VSL#3 probiotic (n = 20), CLA-supplemented (1 g/100 g) (n = 20) or control diets (n = 20) for 32 days and then were infected with H. typhlonius in order to develop experimental colorectal cancer associated with colitis. After the necropsy, all specimens underwent blinded histological examination and were scored 1–4 on mucosal wall thickening (A), leukocyte infiltration (B), adenomas (C) and adenocarcinomas (D). Data are represented as mean ± standard error. Points with an asterisk are significantly different when compared to the control group (P<0.05).
