Biological Roles of Uterine Glands in Pregnancy

Open access

Abstract

All mammalian uteri contain glands in the endometrium that synthesize or transport and secrete substances essential for survival and development of the conceptus (embryo/fetus and associated extraembryonic membranes). This review summarizes information related to the biological roles of uterine glands and their secretions in blastocyst/conceptus survival and implantation, uterine receptivity, and stromal cell decidualization in humans and animal models. The infertility and recurrent pregnancy loss observed in the ovine uterine gland knockout (UGKO) model unequivocally supports a primary role for uterine glands and, by inference, their secretions present in uterine luminal fluid in survival and development of the conceptus. Further, studies with mutant and progesterone-induced UGKO mice found that uterine glands and their secretions are required for establishment of uterine receptivity and blastocyst implantation as well as stromal cell decidualization. Similarly in humans, uterine glands and their secretory products are likely critical regulators of blastocyst implantation, uterine receptivity, and conceptus growth and development during the first trimester. Circumstantial evidence suggests that deficient glandular activity may be a causative factor in pregnancy failure and complications in humans. Thus, an increased understanding of uterine gland biology is important for diagnosis, prevention, and treatment of fertility and pregnancy problems in mammals.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In sheep and other domestic species, interferon τ combines with placental lactogens secreted by the trophoblast to upregulate expression of genes encoding uterine milk proteins and growth factors in the endometrial glands.

    “There is strong evidence in the sheep and other domestic species that interferon τ performs additional functions, combining with placental lactogens secreted by the trophoblast to upregulate the expression of genes encoding uterine milk proteins and growth factors in the endometrial glands (514).”

  • Complete endocrine ablation of gland development in newborn lambs results in cessation of growth of the conceptus and loss of the pregnancy in the adult animal, whereas partial ablation leads to a small, non-expanded conceptus that fails to attach.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
