Summary
Interactions between the conceptus and endometrium of sheep and pigs are essential for establishment and maintenance of pregnancy. In pigs, estrogen-induced redirection of secretion of prostaglandin F 2 α (PGF) into the uterine lumen (exocrine secretion) is antiluteolytic, while sheep conceptuses secrete ovine trophoblast protein-1 which inhibits episodic secretion of PGF from the endometrium which is required for luteolysis. These antiluteolytic mechanisms insure maintenance of functional corpora lutea and secretion of progesterone which stimulates endometrial secretion of factors required to support the developing embryo/conceptus. These secretions include nutrients, as well as proteins that serve as enzymes, transport proteins, and regulatory proteins essential for establishment and maintenance of a successful pregnancy.
