Reduced inflammation and colon carcinogenesis in IL-10KO/IL-37tg mice in the course of chronic colitis. Whole explanted colons from IL-10KO mice (A) and IL-10KO/IL-37tg mice (B) were rolled up from distal to proximal (“swiss role”), transferred to formaldehyde solution for 24 h and subsequently embedded in paraffin. Cross-sections of full-length bowel specimen underwent HE-staining (A–F). (C) Ulceration and high-grade inflammation of IL-10KO mouse. (D) Low-grade infiltration IL-10KO/IL-37tg. (E) Regenerative Hyperplasia with high-grade inflammation in IL-10KO mice. (F) Mild- infiltration in IL-10KO/IL-37tg mouse. Cross-sections of full-length bowel specimen underwent Ki-67-staining (G,H). PT2 carcinoma in IL-10KO mouse (G,I). Healthy tissue of IL-10KO/IL-37tg mouse (H,J).
