Quantitation of mucus-producing cells in duodenum, mid-jejunum, ileum and colon of pigs at 3 days, 3 weeks and 3 months of age (paraffin sections; PAS). A Representative pictures of the PAS-stained paraffin tissue sections of the different intestinal regions in the three age groups. B Percentage of PAS⁺ cells in duodenum, mid-jejunum, ileum and colon in three age groups. Individual mean values ± SD of three animals per age group are plotted. Significant differences between age groups (two-way ANOVA with pairwise comparisons) are presented as *p < 0.05, **p < 0.01, ***p < 0.001 or ****p < 0.0001. Scale bar: 100 µm.
