Fur1ctions of extraembryonic membranes

, 1990
Abstract Several extraembryonic membranes arc interposed between the postimplantation mammalian embryo and the maternal tissue, and these subserve a variety of functions which together provide a well-regulated environment for embryo growth and development.

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.

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
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.

Extraembryonic Membranes and Placentation in the Mexican Snake Conopsis lineata

Journal of Morphology
Extraembryonic 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.

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 ...
