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 During times of maternal stress, developing embryos can be exposed to elevated levels of glucocorticoids, which can affect development and permanently alter offspring phenotype.

Steroid receptors and their regulation in avian extraembryonic membranes provide a novel substrate for hormone mediated maternal effects. [PDF]
Sci Rep, 2019 Exposure 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.

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 ...

Extraembryonic Membranes and Placentation in the Mexican Snake Conopsis lineata
Journal of MorphologyExtraembryonic membranes provide protection, oxygen, water, and nutrients to developing embryos, and their study generates information on the origin of the terrestrial egg and the evolution of viviparity.

No Evidence of Impact of Genetic Sex on Hyperthermia-Induced Neural Tube Defects in Chicken Embryos. [PDF]
Birth Defects ResABSTRACT Background In mammals, cranial neural tube defects (NTDs) are more likely to occur in females. It has been proposed that the sex bias in NTDs was due to the presence of the inactive X chromosome in the somatic cells of female embryos and that the inactive X acted as a heterochromatic sink, competing for silencing factors with the rest of the ...

Conceptus Elongation, Implantation, and Early Placental Development in Species with Central Implantation: Pigs, Sheep, and Cows [PDF]
BiomoleculesSpecies have different strategies for implantation and placentation. Much can be learned about general molecular and cellular biology through the examination and comparison of these differences.

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.
