Role of adipokines in embryo implantation [PDF]
Endocrine Connections, 2021 Embryo implantation is a complex process in which multiple molecules acting together under strict regulation. Studies showed the production of various adipokines and their receptors in the embryo and uterus, where they can influen ce the maternal-fetal ...

Role of microRNAs in embryo implantation [PDF]
Reproductive Biology and Endocrinology, 2017 Failure of embryo implantation is a major limiting factor in early pregnancy and assisted reproduction. Determinants of implantation include the embryo viability, the endometrial receptivity, and embryo-maternal interactions.

Embryo implantation and GnRH antagonists [PDF]
Human Reproduction, 2000 When gonadotrophin-releasing hormone (GnRH) was discovered, the agonist and antagonist of GnRH were developed to control the release of FSH and LH by the gonadotrophs. More than 10 years of research were needed to develop a GnRH antagonist free of histamine release.

Development, 2023 ABSTRACT Embryo implantation in humans is interstitial, meaning the entire conceptus embeds in the endometrium before the placental trophoblast invades beyond the uterine mucosa into the underlying inner myometrium. Once implanted, embryo survival pivots on the transformation of the endometrium into an anti-inflammatory placental bed ...

Developmental Biology, 2000 A lesson learned from modern developmental biology is the striking degree of conservation of strategies and molecules used to program developmental events in species as diverse as insects, birds, amphibians, and mammals. Nonetheless, mammals retain distinctions with regard to the strategies used to protect and nourish their offspring during development,

Single-cell analysis of mouse uterus at the invasion phase of embryo implantation
Cell & Bioscience, 2022 Background Embryo implantation into the uterus is a crucial step for human reproduction. A hypothesis has been proposed that the molecular circuit invented by trophoblasts for invasive embryo implantation during evolution might be misused by cancer cells

The effects of aging on molecular modulators of human embryo implantation
iScience, 2021 Summary: Advancing age has a negative impact on female fertility. As implantation rates decline during the normal maternal life course, age-related, embryonic factors are altered and our inability to monitor these factors in an unbiased genome-wide ...
