Immunohistology of clotting factor V in human extraembryonic membranes

Placenta, 1987
Blood clotting Factor V was studied on fixed and unfixed cryostat sections of term human placentae, basal plates, amniochorions, and first-trimester placentae by using one- and two-colour immunofluorescence. A monoclonal antibody (GB36) which reacts with cytotrophoblast was used to identify cytotrophoblast.

Protein synthesis by chick (Gallus domesticus) extraembryonic membranes

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1993
1. 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.

Embryology of the sheep. I. Extraembryonic membranes and the development of body form

Journal of Morphology, 1972
AbstractThe developmental anatomy of the sheep in the early prenatal period (14 to 34 days) was studied using embryos of known coital age, and embryos of known size with estimated coital age. Characteristics of the embryos were studied by gross observation under the dissecting microscope, and by means of serial sections.

Radioautographic studies of DNA synthesis in the developing extraembryonic membranes of the mouse

The Anatomical Record, 1967
AbstractTritiated thymidine was injected into pregnant BALB/c mice intravenously at 8, 10, 12, 14 and 16 days of pregnancy. Radioautographs were prepared in order to determine the extent of synthesis of DNA in the extraembryonic membranes at the above stages of gestation. The extent of synthesis of DNA was expressed as a radioactive index. The index is

Somatic polyploidy in extraembryonic membranes of the snake,Elaphe guttata

Protoplasma, 1993
Video-densitometric DNA measurements of Feulgenstained tissues of 42 day old eggs of the corn snake,Elaphe g. guttata (Columbridae, Serpentes), revealed a basic DNA content of 2C=2.17 pg, with somatic polyploidy in the allantois, the chorioallontois, the yolk sac, and other extraembryonic membranes.

Establishment of a rat placental cell line expressing characteristics of extraembryonic membranes

Developmental Biology, 1987
A cell line was derived from midgestation chorioallantoic placental explants of the outbred Holtzman rat. The cell line was found to express characteristics of extraembryonic membranes and to grow when introduced into allogeneic hosts. Growth in allogeneic hosts was detected following intraperitoneal injection of the cells but not following ...

Morphogenesis of extraembryonic membranes and placentation in Mabuya mabouya (Squamata, Scincidae)

Journal of Morphology, 2003
AbstractTopological and histological analyses of Mabuya mabouya embryos at different developmental stages showed an extraembryonic membrane sequence as follows: a bilaminar omphalopleure and progressive mesodermal expansion around the whole yolk sac at gastrula stages; mesodermal split and formation of an exocoelom in the entire embryonic chamber at ...

Expression of CD59, a Human Complement System Regulatory Protein, in Extraembryonic Membranes

International Archives of Allergy and Immunology, 2009
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 ...

Fur1ctions of extraembryonic membranes

1990
Abstract Several extraembryonic membranes arc interposed between the postimplantation mammalian embryo and the maternal tissue, and these subserve a variety of functions which together provide a well-regulated environment for embryo growth and development.

Structure and function of the extraembryonic membrane persisting around the larvae of the parasitoid Toxoneuron nigriceps

Journal of Insect Physiology, 2006
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 ...
