Expression of CD59, a Human Complement System Regulatory Protein, in Extraembryonic Membranes
International Archives of Allergy and Immunology, 1993 CD59 (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 ...

Molecular Reproduction and Development, 1997 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.

Clinical Genetics, 1974 The study concerns the diagnosis of fetal condition early in pregnancy ‐ within the first trimester. An instrument was designed to allow biopsy of the extraembryonic membranes under visual control. The instrument was tested in 95 pregnant women prior to legal termination of pregnancy.

Analyses of cell surface and secreted proteins of primary cultures of mouse extraembryonic membranes
Developmental Biology, 1979 Abstract 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.

Nature, 1975 RANDOM X inactivation makes the female mammal a natural mosaic for clones of cells having either the maternally derived X (Xm) or paternally derived one (Xp) which is genetically inactive1. There are, however, instances in which inactivation is obviously not random2–7.

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2012 ABSTRACTYolk is the primary source of calcium for embryonic growth and development for most squamates, irrespective of mode of parity. The calcified eggshell is a secondary source for embryonic calcium in all oviparous eggs, but this structure is lost in viviparous lineages.

Protein synthesis by chick (Gallus domesticus) extraembryonic membranes
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19931. 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.

Paternal X chromosome expression in extraembryonic membranes of XO mice
Journal of Experimental Zoology, 1979AbstractThe 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 ...
