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.

Extraembryonic membrane development in a reproductively bimodal lizard, Lacerta (Zootoca) vivipara
Zoology, 2004Reproductive mode has been remarkably labile among squamate reptiles and the evolutionary transition from oviparity to viviparity commonly has been accompanied by a shift in the pattern of embryonic nutrition. Structural specializations for placental transfer of nutrients during intrauterine gestation are highly diverse and many features of the ...

Fur1ctions of extraembryonic membranes
1990Abstract 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.

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 ...

Abstract Highly mineralized rigid‐shelled eggs characterize one lineage of gekkotans. In contrast, poorly mineralized flexible‐shelled eggs characterize basal lineages of gekkotans and all other squamates. Low oxygen permeability of rigid‐shelled eggs is associated with small eggs and hatchlings, and long incubation lengths compared ...
