a RT-PCR data depicting Il22Ra1 expression in the terminal ileum of naive Il22Ra1fl/fl;Villin-cre+/− mice. b Representative phloxine-tartrazine staining image (left panel) and average Paneth cell number/crypt (right panel) in the ileum of naive Il22Ra1fl/fl;Villin-cre+/− mice. c RT-PCR analysis of Lyz1 and Mmp7 expression from ileal tissues of naive Il22Ra1fl/fl;Villin-cre+/− mice. d Representative immunofluorescence image of Lyz1 and MMP7 in the ileal tissue of naive Il22Ra1fl/fl;Villin-cre+/− mice. e RT-PCR analysis of SFB levels in the terminal ileum of naive Il22Ra1fl/fl;Villin-cre+/− mice. f RT-PCR analysis of Il17a, Il22 and Saa1/2 expression from the terminal ileum of naive Il22Ra1fl/fl;Villin-cre+/− mice. g Layout of Lgr5-EGFP-creERT2;RosaLSLtdTomato treatment with tamoxifen and either vehicle (PBS) or IL-22.Fc (80 μg/mouse). h Representative immunofluorescence images of TdTomato expression in vehicle or IL-22.Fc treated Lgr5-EGFP-creERT2;RosaLSLtdTomato mice. i RT-PCR analysis of Lyz1 and Mmp7 expression in the terminal ileum of these mice. Figure 2b–f were generated from two independent experiments. Figure 2d is representative of at least four mice in each group Figure 2h, i are generated form 2–3 mice per group. Data are presented as mean ± SEM on all graphs except Fig. 2i (mean ± SD). Scale bars in relevant figures equal 100 μm. *P ≤ 0.05; **P ≤ 0.01; ***P ≤ 0.001 (Mann–Whitney test, two-tailed).
