Studies on the equine placenta III. Ultrastructure of the uterine glands and the overlying trophoblast

Abstract
Ultrastructural studies of the uterine glands at intervals during pregnancy in the mare show that secretory activity continues after formation of the placental exchange units. The nature of the glandular secretion appeared initially to be proteinaceous, but cellular debris was also present during the last 3rd of gestation. These secretions were absorbed by the trophoblast overlying the mouths of the glands. The fate of the secretions and their significance for the fetus and placenta are unknown.
