title: Histology of the adult mouse oviduct and endometrium following a single prenatal exposure to diethylstilbestrol.
abstract: Light microscopy was used to examine the oviduct and endometrium of offspring from mice administered DES (10 micrograms/kg in 0.1 cc of corn oil, subcutaneously) or corn oil alone on Day 15 of gestation. Offspring were sacrificed at 5, 7 and 9 months of age. Oviduct changes in DES exposed offspring included numerous abnormal secretory cells which lined the mucosal folds of the isthmus. These cells contained a distinct granular cytoplasm which was eosinophilic and a nucleus displaced towards the apical surface. In addition both the ampulla and isthmus had mucosal folds which extended to the serosal surface and an accumulation of subepithelial fibrinoid material. Endometrial changes included squamous metaplasia of both the surface and glandular epithelial layer as well as extensive cystic glandular hyperplasia. In addition the endometrial connective tissue stroma exhibited fibrinoid accumulation. These changes may reflect an altered endocrine environment resulting from ovarian abnormalities during adulthood.
