Figure 1
Patterns of expression of tissue transglutaminase in duodenal biopsies of celiac disease. (a) Positive surface mucosa labelling with absent staining in crypts. (b) Positive staining in both surface mucosa and in crypts. (c) Absence of staining in both surface epithelium and crypts. (immunoperoxidase 20x).
