Abstract
In the present study isolated uterine epithelial cells from normal rabbits were maintained in culture on free floating rat-tail collagen matrix, and the morphological characteristics of these cells were examined. Additionally, the pattern of protein synthesis and secretion by rabbit uterine epithelial cells grown on free floating collagen gels following estradiol and/or progesterone treatment in vitro was examined. Isolated epithelial cells cultured on collagen gels in complete medium containing serum attached to form monlayers, and eventually the gels became free floating and contracted giving rise to luminal arrangements. These cells were cytokeratin positive epithelial cells and were ultrastructurally polarized. These cells also exhibited differential upregulation and down regulation in the synthesis and secretion of proteins in response to estradiol, progesterone, and estradiol plus progesterone. Additionally, a permissive action between progesterone and estradiol in the synthesis of two species of secretory proteins was observed. It however remains to be examined whether different species of proteins produced in vitro in response to estradiol and progesterone bear any association with physiological states in reproductive cycle in this species.
