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 ...

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.

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 ...

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

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
