Gut microbiome functions inferred by PICRUStII from 16S rRNA gene sequences among the three groups (the control group, the TNBS group and the TNBS + MSC group). a The blue, golden yellow and green bar graphs indicate the inferred metabolism value of control group, TNBS group and TNBS + MSC group. KEGG orthology was used for functional categorization. STAMP3 was used for functional profiling. Elevated metabolic pathways after modelling. b Decreased metabolic pathways after modelling. A box plot shows the top quartile, median, and bottom quartile, while white stars indicate the average and a plus sign indicates the outlier. All differences were analysed using one-way ANOVA followed by the Tukey–Kramer post hoc test. The multiple comparisons were not corrected
