Development of inflammation, atrophy, and hyperplasia occurs earlier in Ebi3-/- mice. (A) Representative H&E-stained sections of murine gastric corpus from 2-month-old BALB/c, TxA23, and Ebi3 knockout. Yellow box outlines high-magnification inset showing the degree of inflammation, parietal cell atrophy, mucinous hyperplasia/metaplasia, and mucosal hyperplasia. (B) Pathologic scores for inflammation, parietal cell atrophy, mucinous hyperplasia/metaplasia, and mucosal hyperplasia. Each dot represents the overall score given to 3 areas of gastric corpus from an individual 2-month-old mouse. N = 7–11 mice per group from more than 3 experiments. (C) Representative H&E-stained sections of murine gastric corpus from 12-month-old control TxA23 and TxA23xEbi3 knockout mice. Red arrows identify areas in Ebi3-/- mice where glandular structures invade the submucosa and muscularis. A red box outlines abnormal branching glands and cellular atypia within the gastric corpus. N = 4 mice per group in at least 2 experiments.
