Endocrine Activity of Extraembryonic Membranes Extends beyond Placental Amniotes [PDF]
PLoS ONE, 2009 During development, all amniotes (mammals, reptiles, and birds) form extraembryonic membranes, which regulate gas and water exchange, remove metabolic wastes, provide shock absorption, and transfer maternally derived nutrients. In viviparous (live-bearing) amniotes, both extraembryonic membranes and maternal uterine tissues contribute to the placenta ...

Avian extraembryonic membranes respond to yolk corticosterone early in development
Biology OpenABSTRACT During times of maternal stress, developing embryos can be exposed to elevated levels of glucocorticoids, which can affect development and permanently alter offspring phenotype. In placental species, the placenta mediates fetal exposure to maternal glucocorticoids via metabolism, yet the placenta itself responds to ...

Journal of Animal Science and BiotechnologyAbstract Background Proteome characterization of the porcine endometrium and extraembryonic membranes is important to understand mother-embryo cross-communication. In this study, the proteome of the endometrium and chorioallantoic membrane was characterized in pregnant sows (PS) during early gestation (d 18 and 24 of ...

Semiautonomous Development of the Extraembryonic Membranes in the Chicken Embryo
Poultry Science, 2006 Based on an old paradigm that the extra-embryonic membranes develop semiautonomously from the embryo, it can also be postulated that subembryonic fluid (SEF) will be formed semiautonomously against embryonic growth, because the formation of SEF is mediated by the yolk sac membrane.

Morphogenetic functions of extraembryonic membranes in insects [PDF]
Current Opinion in Insect Science, 2016 Morphogenetic functions of the amnioserosa, the serosa, the amnion, and the yolk sac are reviewed on the basis of recent studies in flies (Drosophila, Megaselia), beetles (Tribolium), and hemipteran bugs (Oncopeltus). Three hypotheses are presented. First, it is suggested that the amnioserosa of Drosophila and the dorsal amnion of other fly species ...

The involvement of the proamnion in the development of the anterior amnion fold in the chicken. [PDF]
PLoS ONE, 2014 The amnion was one of the most important evolutionary novelties in the animal kingdom, allowing independence of water for reproduction and subsequent exploration of terrestrial habitats, and is therefore an important structure to understand evolution. We

Life, 2022 Pregnancy loss predominantly occurs during the first 3–4 weeks due to fertilization failure or early embryonic losses in cattle. Insufficient biochemical communication between conceptus (embryo plus extraembryonic membranes) and endometrium has been ...

A system to enrich for primitive streak-derivatives, definitive endoderm and mesoderm, from pluripotent cells in culture [PDF]
, 2012 Two lineages of endoderm develop during mammalian embryogenesis, the primitive endoderm in the pre-implantation blastocyst and the definitive endoderm at gastrulation.
