The colonic mucus barrier serves as a primary defense against enteric pathogens; destruction of this mucus layer has been observed in ulcerative colitis patients. This study aims to investigate the possibility of rebuilding the colon mucus layer through puerarin supplementation, which can stimulate mucin secretion and goblet cells differentiation. After puerarin supplementation, the thickness of colon mucus layer was increased and the permeability was reduced. The erosion of intestinal epithelium by bacteria was blocked, and the loss of epithelial integrity was alleviated. Puerarin also altered the composition of mucin-utilizing bacteria, which influenced the mucus permeability. Levels of short-chain fatty acids (SCFAs) were increased after puerarin supplementation, which as a direct source of energy for the proliferation of epithelia and goblet cells. This study demonstrated that enhancement of mucin secretion to relieve ulcerative colitis (UC) by puerarin supplementation is feasible, and the regulation of mucin-utilizing bacteria and the increased levels of SCFAs may be the main reasons.
