Fig. 4: Thickness of the colon mucus layer in fecal transplant model mice.

A Schematic diagram of the stool transplant mouse model. B Fluorescent immunostaining of MUC2 in the colon of mice and alcian blue staining of sections of the colon. Scale bars, 50 μm. C Measurement of the colonic mucus layer thickness. In each group, the colonic mucus layer thickness was measured at nine points and the means were compared. Error bars represent the SEM. (*p < 0.05).
