Definition of the cellular source of IL-22. Definition of the cellular source of IL-22. (A) Weight and colonoscopic analysis of [Cx3cr1cre:Il10rafl/fl > WT], [Cx3cr1gfp/+ > WT], or [Cx3cr1cre:Il10rafl/fl:Il-22−/− > WT] BM chimeras. Colonoscopy was performed 6 weeks after transplant. n.s., non significant, P > 0.05; *P ≤ 0.05. Data were collected from two independent experiments, n ≥ 3 in each. (B) qRT-PCR analysis of Il22, Cxcl1, and Cxcl5 expression in whole-tissue extracts of colons of indicated BM chimeric mice. Data were collected from two independent experiments, n = 3 to 5 in each group. (C) qRT-PCR analysis of Il22 expression in whole-tissue extracts of colons of indicated BM chimeric mice. Data are from one of two representative experiments. Weight (left) and colonoscopic (right) analysis of [Cx3cr1cre:Il10rafl/fl:Il22−/− > WT] and [Cx3cr1cre:Il10rafl/fl:Il22−/− > Il22−/−] BM chimeras. Colonoscopy was performed 7 weeks after transplant. Weight data are from one of two representative experiments, n = 3 to 4 in each group; colonoscopic data are collected from two experiments. n = 3 to 4 in each group.
