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 ...

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 ...

Laminin γ1 C-terminal Glu to Gln mutation induces early postimplantation lethality
Life Science Alliance, 2018 Mouse embryos with an ablated ability of integrins to bind laminins are still able to form basement membranes, but die just after implantation because of deficient extraembryonic development.

Periostin as a Biomarker of the Amniotic Membrane
Stem Cells International, 2012 Tracing the precise developmental origin of amnion and amnion-derived stem cells is still challenging and depends chiefly on analyzing powerful genetic model amniotes like mouse. Profound understanding of the fundamental differences in amnion development
