Mucin (Muc-1) expression is differentially regulated in uterine luminal and glandular epithelia of the baboon (Papio anubis).

Changes in the organization and composition of apical cell surface glycoconjugates accompany the transition of luminal epithelial cells from the prereceptive state of the uterus in many species. In spite of the biological and clinical significance of this process, few molecular markers have arisen as useful predictors of uterine receptivity. Recent studies in mice demonstrate that the transmembrane mucin glycoprotein, Muc-1, is abundantly expressed at the apical surface of luminal epithelia under most conditions and is invariably reduced in receptive uteri.

Secretory proteins and growth factors of the baboon (Papio anubis) uterus: potential roles in pregnancy.

The primate endometrium undergoes distinct morphological changes during the menstrual cycle. These alterations are regulated by the steroid hormones, estrogen and progesterone. Several lines of evidence suggest that some of these hormonally induced changes may be modulated by growth factors.
