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

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 ...

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.

New Insights Into the Role of β-NGF/TrKA System in the Endometrium of Alpacas During Early Pregnancy
Frontiers in Veterinary Science, 2021 One striking reproductive feature in South American camelids is that more than 90% of gestations are established in the left uterine horn (LUH). This phenomenon could be related to a differential vascular irrigation of the LUH.

Trophoblast biology: Forum introduction
Reproductive Biology and Endocrinology, 2004 In mammals, a carefully orchestrated dialogue between the mother and conceptus (embryo/fetus and associate extraembryonic membranes) is initiated during the peri-implantation period of pregnancy as the trophoblast develops, functions to signal pregnancy ...
