Goblet cell morphology in DSS + TNF-α neutralizing antibody treated group in comparison to only DSS treatment.

Data are presented as % of goblet cells ± SEM. *P[28]. Filled goblet cells: goblet cells with intact mucus granules; Releasing mucus: cells releasing mucus with PAS-stained mucus emerging as a thick stream; Empty goblet cells with PAS stained mucus absent from cells exhibiting a deep concave cavitation of the apical surface. ND: Not determined as the epithelial layer and crypts on day 9 of DSS treatment was destroyed or too damaged in the ulcerated site.
