The embryo of Toxoneuron nigriceps (Hymenoptera, Braconidae) is surrounded by an extraembryonic membrane, which, at hatching, releases teratocytes and gives rise to a cell layer embedding the body of the 1st instar larva. This cell layer was studied at different developmental times, from soon after hatching up to the first larval moult, in order to ...

, 2020 Expression of CD59, a Human Complement System Regulatory Protein, in Extraembryonic Membranes
International Archives of Allergy and Immunology, 1993CD59 (leukocyte cluster of differentiation antigen 59), is a phosphatidylinositol glycan-anchored membrane protein that inhibits lysis of cells by terminal complement system components. To further define complement regulatory proteins relevant to pregnancy, this study characterized the expression of CD59 in human extraembryonic membranes ...

Analyses of cell surface and secreted proteins of primary cultures of mouse extraembryonic membranes
Developmental Biology, 1979Abstract Procedures have been developed for primary culture of 13th day mouse parietal and visceral endoderm, yolk sac mesoderm, and amnion cells. We have analyzed cell surface and secreted proteins of these cultures by labeling the cells with radioactive iodine, glucosamine, or amino acids, and/or by immunofluorescence.

AbstractAmniote embryos are supported and nourished by a suite of tissues, the extraembryonic membranes, that provide vascular connections to the egg contents. Oviparous reptiles share a basic pattern of development inherited from a common ancestor; a vascular chorioallantoic membrane, functioning as a respiratory organ, contacts the eggshell and a ...

Little information is available describing the development of endoparasitic Hymenoptera prior to hatching of the first instar larva. The present study reveals that in Cotesia congregata, and likely other braconid wasp parasites, the serosa and amnion comprise separate layers encasing the developing first instar larva. Examination of newly hatched first

AbstractPseudemoia pagenstecheri is a viviparous Australian scincid lizard in which the maternal–embryonic placental interface is differentiated into structurally distinct regions. The chorioallantoic placenta contains an elliptical‐shaped region, the placentome, characterized by hypertrophied uterine and embryonic epithelial cells supported by dense ...

A major secretory protein produced by bovine chorioallantoic membranes, in vitro, was previously identified as the carboxyl-propeptide of alpha-1 type III collagen. In the present study, the protein and gene expression of procollagen III by bovine chorioallantois between days 17 and 45 of pregnancy was investigated.
