Expression of stem, goblet and Paneth cells in mouse ileal tissue. Quantification of cell numbers and representative images of (A) stem cells (leucine-rich repeat- G-protein coupled receptor 5, LRG5) positive cells stained red; (B) goblet cells (mucin-2, MUC2) positive cells stained green and (C) Paneth cells (defensin 5, DEFA5) positive cells stained red in wild-type (blue square, blue) and CFTR-null (Cftr−/−) (yellow inverted triangle, yellow) mice from group 1 and group 2. Nuclei are stained blue with 4′,6-diamidino-2-phenylindole (DAPI). Box and whisker plots represent the number of cells counted expressing LRG5, MUC2 and DEFA5 as median ± 95% CI (n = 6 for each mice group). Statistical significance was determined by One-way ANOVA with differences between means identified, using Tukey’s multiple comparison post hoc test; ****P < 0.0001. Images are 400 × (A), 100 × (B) and 200 × (C) magnified. The insets enclosed in white boxes show higher magnification images of the areas enclosed by the dashed lines.
