Differential analysis of intestinal microbiota and metabolites in mice with dextran sulfate sodium-induced colitis

Figure 4 Intestinal mucus loss was more pronounced in dextran sulfate sodium-induced colitis mice with bacteria. A: Alcian blue staining; B: Percentage of positively stained areas; C: Percentage of MUC2-positive stained areas; D: Mucin2 (MUC2) immunofluorescence staining. A: Microbiota^- colitis group, F: Blank group, G: Microbiota⁺ colitis group. MUC2: Mucin2. Compared with the blank group, ^aP < 0.01. Compared with the microbiota⁺ colitis group, ^dP < 0.05.
