  • Title: Tumors of female offspring of mice exposed prenatally to diethylstilbestrol.
    Author: Walker BE.
    Journal: J Natl Cancer Inst; 1984 Jul; 73(1):133-40. PubMed ID: 6588221.
    Abstract:
    Strain CD-1 female mice exposed prenatally to diethylstilbestrol (DES) (CAS: 56-53-1; alpha,alpha'-diethyl-4,4'-stilbenediol) were mated to unexposed males. Female offspring of these matings were raised to the stage of terminal illness. They were never exposed to DES and so have been referred to as "DES-lineage mice." Ten uterine adenocarcinomas and 5 ovarian cystadenocarcinomas were found in 40 DES-lineage mice. These findings were significantly different from the absence of such tumors in 24 "vehicle-lineage" mice whose mothers had received injections only of oil and alcohol. The types of tumors that commonly occur spontaneously in the CD-1 strain appeared with comparable frequency in the 2 groups of mice. The DES-lineage mice did not show the increased frequency of adenomyosis and squamous metaplasia of the uterus, nor the reduced frequency of corpora lutea seen in mice exposed prenatally to DES.
