iNOS immunoreactivity in gastric carcinoma tissue. (A) A focal/weak/luminal immunoreaction is observed in a well-differentiated adenocarcinoma case. (B) Intense/diffuse/cytoplasmic iNOS immunoreactivity is observed in a poorly differentiated tumor tissue. (C) No iNOS expression was detected in non-neoplastic glands in the same case. (D) Despite focal/weak iNOS immunoreactivity in well-differentiated tumor areas, there is strong iNOS expression in tumor cells of the invasive phenotype. iNOS immunoreactivity is demonstrated in endothelial cells (E) and fibroblasts (F) in the tumor stroma.
