Abstract

A mouse endometrial cell population has been isolated by mild tryptic digestion of the uterine lining. The cells were morphologically similar to endometrial gland cells in the intact mouse endometrial gland. The endometrial cells had a modal chromosome number of 66. The cells were adherent to glass as well as plastic and contained numerous large refractile, osmophilic, non‐membrane‐limited granules which stain with periodic acid‐Schiff reagent but do not stain with oil red O, Sudan black, or Alcian blue. Cell growth was responsive to 17β‐estradiol; cell number increased 1.34‐fold in 4 days in the presence of 10−8 M estradiol. The cells are not tumorigenic. The cells showed induction of aryl hydrocarbon hydroxylase (AHH) activity when 2,3,7,8‐tetrachlorodibenzo‐p‐dioxin (TCDD) was added to the growth media for 24 h. AHH activity and its induction were investigated with cells grown in the presence and absence 10−8 M estradiol. Cells grown in media containing estradiol exhibited a 6.2‐fold induction by TCDD; cells grown without estradiol gave an 8.4‐fold induction of AHH activity. AHH activity and its induction by TCDD were demonstrated in cells grown with fetal calf serum that had been pretreated with dextran‐coated charcoal to remove endogenous steroids. Benzanthracene failed to induce AHH activity significantly.
