Extraembryonic membrane morphology in greater rheas (Rhea americana americana Linnaeus, 1758) [PDF]
Zoomorphology, 2023 The greater rhea, Rhea americana, is a wild ratite of high scientific importance and significant and zootechnical value, especially considering the current development state of Brazilian poultry production, where research aimed at increasing the productivity of these animals has become extremely relevant.

Neural tube opening and abnormal extraembryonic membrane development in SEC23A deficient mice [PDF]
Scientific Reports, 2015 AbstractCOPII (coat protein complex-II) vesicles transport proteins from the endoplasmic reticulum (ER) to the Golgi. Higher eukaryotes have two or more paralogs of most COPII components. Here we characterize mice deficient for SEC23A and studied interactions of Sec23a null allele with the previously reported Sec23b null allele. SEC23A deficiency leads

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 ...

Extraembryonic Membranes and Placentation in the Mexican Snake Conopsis lineata
Journal of MorphologyABSTRACTExtraembryonic 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. In this research, the morphology of the extraembryonic membranes and the types of placentation in the viviparous snake Conopsis lineata are ...

Life, 2022 Pregnancy loss predominantly occurs during the first 3–4 weeks due to fertilization failure or early embryonic losses in cattle. Insufficient biochemical communication between conceptus (embryo plus extraembryonic membranes) and endometrium has been ...

Oldest preserved umbilical scar reveals dinosaurs had ‘belly buttons’
BMC Biology, 2022 Background In egg-laying amniotes, the developing embryo is tethered to a number of the extraembryonic membranes including the yolk sac and allantois that deliver oxygen and nutrients and remove metabolic waste products throughout embryonic development ...

In ovo model in cancer research and tumor immunology
Frontiers in Immunology, 2022 Considering cancer not only as malignant cells on their own but as a complex disease in which tumor cells interact and communicate with their microenvironment has motivated the establishment of clinically relevant 3D models in past years.
