Histological stain to evaluate the protective effect of TDNPs 2 on colitis. A Representative H&E-stained colon. Inflammatory cell infiltration was indicated by arrowheads. B Colonic goblet cells were stained by Alcian blue. As goblet cells produce mucins, Alcian blue was used to highlight the goblet cell population. C E-cadherin expression was detected by immunofluorescence. Scale bar: 50 μm
