(A) Upper histogram depicts quantification of Ki67 staining within healthy appearing tissue of the colon B6, CD4CreIL-10fl/fl, IL-10−/−, APCΔ468, CD4CreIL-10fl/flAPCΔ468, and IL-10−/−xAPCΔ468 mice. Data represent the ratio of the height of Ki67-staining cells/total height of each villi per 200X view. Lower histogram (mean ± SEM) depicts colon length of mice in millimeters (mm).
(B) Representative Ki67 staining of colons. Black bar represents average height of Ki67+ cells within the villi.
(C) Colonic polyp counts of the various mouse strains.
(D) Photographs of distal colon segments from APCΔ468, CD4CreIL-10fl/flAPCΔ468, and IL-10−/− mice.
(E) Upper panels show representative 100X colonic polyp from an APCΔ468, CD4CreIL-10fl/flAPCΔ468, and IL-10−/−xAPCΔ468 mice. Double-headed arrows depict width of expanded stromal regions. Lower panels show representative 200X micrographs of colonic polyps from APCΔ468, IL-10−/−xAPCΔ468 and CD4CreIL-10fl/flAPCΔ468 mice, showing crypts at the basal surface of the polyp. Inlay images at 400X, basal crypts of the three mouse strains.
