Monotreme development with particular reference to the extraembryonic membranes

The Journal of Experimental Zoology, 1993
AbstractThis paper considers many of the salient features of monotreme development, particularly morphogenesis of the extraembryonic membranes.The uterine endometrium of both monotremes and marsupials exhibits a progesterone driven luteal phase where accelerated utilization of endometrial nutrients is evidenced by a rapid post‐primitive streak ...

Extraembryonic tissue in chelicerates: a review and outlook

Philosophical Transactions of the Royal Society B: Biological Sciences, 2022
The formation of extraembryonic membranes (EEMs) contributes to the proper development of many animals. In arthropods, the formation and function of EEMs have been studied best in insects.

Antioxidative signalling pathways regulate the level of reactive oxygen species at the endometrial–extraembryonic membranes interface during early pregnancy

International Journal of Biochemistry and Cell Biology, 2012
Conceptus (embryo and associated extraembryonic membranes) implantation and development require a reciprocal biochemical and physical interactions between the extraembryonic membranes and the endometrium.

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.

Extraembryonic development in insects and the acrobatics of blastokinesis [PDF]

Developmental Biology, 2008
Extraembryonic development is familiar to mouse researchers, but the term is largely unknown among insect developmental geneticists. This is not surprising, as the model system Drosophila melanogaster has an extremely reduced extraembryonic component ...

Formation of the Placenta and Extraembryonic Membranes

Annals of the New York Academy of Sciences, 1998
ABSTRACT: In eutherian mammals, the first cell types that are specified during embryogenesis are committed to form extraembryonic (placenta and fetal membranes) rather than embryonic structures. The trophoblast cell lineage, for example, forms at the morula‐to‐blastocyst transition: cells at the periphery of the morula become trophoblast, whereas ...

Paternal X chromosome expression in extraembryonic membranes of XO mice

The Journal of Experimental Zoology, 1979
AbstractThe paternally derived allelic form of the X chromosome linked enzyme phosphoglycerate kinase (PGK‐1) is expressed in both the fetus and extraembryonic membranes of 9.5 day post coitum XO (XPO) mouse conceptuses. Previous studies on trophectoderm and primitive endoderm derived extraembryonic membranes in XX conceptuses suggest expression of ...

Protein synthesis by chick (Gallus domesticus) extraembryonic membranes

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1993
1. The protein synthesis in chorioallantoic membrane (CAM), amniotic membrane (AM) and yolk sac (YS) were studied by in vitro culture with 14C L-glutamic and immunoautoradiography. 2. The yolk sac synthesizes transferrin, alpha-fetoprotein (AFP) and serum albumin. These three proteins are also synthesized, but only in slight amounts, by AM.

Immunohistology of clotting factor V in human extraembryonic membranes

Placenta, 1987
Blood clotting Factor V was studied on fixed and unfixed cryostat sections of term human placentae, basal plates, amniochorions, and first-trimester placentae by using one- and two-colour immunofluorescence. A monoclonal antibody (GB36) which reacts with cytotrophoblast was used to identify cytotrophoblast.
