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
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.

Proteomic Dynamics of Ovine Allantoic and Amniotic Fluids During Gestation. [PDF]

Reprod Domest Anim
ABSTRACT Gestational success in ruminants depends on the maintenance of a dynamic maternal–foetal microenvironment, resulting from complex interactions among the conceptus, extraembryonic membranes, maternal tissues, and gestational fluids. This study performed a comparative and longitudinal proteomic characterization of allantoic and amniotic fluids ...

Progressive Cellularization of Blastoderm and Extraembryonic Tissue Formation in the Ant Camponotus floridanus. [PDF]

J Exp Zool B Mol Dev Evol
Illustration of the process of cellularization in Camponotus floridanus (top row) compared to Drosophila melanogaster (bottom row). Progressive direct formation of differentiating blastoderm mode is depicted using hexagons that represent energids (without borders) and cells (with borders). Colors of nuclei represent different cell types.

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.

Integrin-Dependent Apposition of Drosophila Extraembryonic Membranes Promotes Morphogenesis and Prevents Anoikis [PDF]

Current Biology, 2004
Two extraembryonic tissues form early in Drosophila development. One, the amnioserosa, has been implicated in the morphogenetic processes of germ band retraction and dorsal closure. The developmental role of the other, the yolk sac, is obscure.By using live-imaging techniques, we report intimate interactions between the amnioserosa and the yolk sac ...

Conceptus Elongation, Implantation, and Early Placental Development in Species with Central Implantation: Pigs, Sheep, and Cows [PDF]

Biomolecules
Species 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 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.
