In this study, stomach epithelial cells from adult nonpregnant, pregnant lactating mice were examined by histochemical, immunohistochemical and ultrastructural methods. Tissue samples taken from different groups were stained with haematoxylin-eosin and PAS-alcian blue and semithin sections were stained with toluidin blue for light microscopic examination. For ultrastructural examination ultrathin sections were stained with uranyl acetate and lead citrate. Additionally, by applying immunoperoxidase method, the distribution of EGF receptors of all groups was studied.
