Endocrine activity of extraembryonic membranes extends beyond placental amniotes. [PDF]

PLoS ONE, 2009
BackgroundDuring 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.

Avian extraembryonic membranes respond to yolk corticosterone early in development [PDF]

Biology Open, 2023
ABSTRACT 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 ...

In-depth proteome characterization of endometrium and extraembryonic membranes during implantation in pig [PDF]

Journal of Animal Science and Biotechnology
Background Proteome characterization of the porcine endometrium and extraembryonic membranes is important to understand mother-embryo cross-communication.

Steroid receptors and their regulation in avian extraembryonic membranes provide a novel substrate for hormone mediated maternal effects. [PDF]

Sci Rep, 2019
AbstractExposure of the vertebrate embryo to maternal hormones can have long-lasting effects on its phenotype, which has been studied extensively by experimentally manipulating maternal steroids, mostly androgens, in bird eggs. Yet, there is a severe lack of understanding of how and when these effects are actually mediated, hampering both underlying ...

Extraembryonic membrane morphology in greater rheas (Rhea americana americana Linnaeus, 1758). [PDF]

Zoomorphology, 2023
The greater rhea, Rhea americana, is a wild ratite of high scientific importance and significant and zootechnical value, especially considering the current development state of Brazilian poultry production, where research aimed at increasing the productivity of these animals has become extremely relevant.

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 ...

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.

Neural tube opening and abnormal extraembryonic membrane development in SEC23A deficient mice [PDF]

Scientific Reports, 2015
AbstractCOPII (coat protein complex-II) vesicles transport proteins from the endoplasmic reticulum (ER) to the Golgi. Higher eukaryotes have two or more paralogs of most COPII components. Here we characterize mice deficient for SEC23A and studied interactions of Sec23a null allele with the previously reported Sec23b null allele. SEC23A deficiency leads

Expression of tripartite motif family-like protein 1 and 2 in early conceptus development and placentation in the pig [PDF]

Reproduction and Fertility
The eutherian placenta is highly complex, evolving to regulate the inflammatory phase of pregnancy during conceptus attachment and placental tissue development. Tripartite motif family-like (TRIMLs) proteins are implicated in downregulating inflammation.
