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.

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.

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.

Comparative Study of Prenatal Development Between
The Anatomical Record, 2018 We presented a comparative study of two species of South American bats, Myotis albescens and Eumops patagonicus, about prenatal development. This study was carried out using 60 specimens, which were measured and photographed, and the embryonic stage was ...

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.

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.
