“…The high weight loss of the ED eggs is difficult to explain but may, in part, be the result of unregulated water loss due to some functional difference such as poor albumen quality or other physical attribute of the egg. Although embryonic death may alter tne rate of gas exchange and weight loss (Tyler and Simkiss, 1959;Kayar et al, 1981), the consistent differences in weight loss between egg types found in this study and that of Peebles and Marks (1991) suggests that differences in rate of water loss may be causally related to embryonic mortality.…”

Relationship Between Shell Porosity, Shell Thickness, Egg Weight Loss, and Embryonic Development in Japanese Quail Eggs

Japanese quail eggs that hatched (H) or pipped (PIP) exhibited less weight loss through 15 d of incubation than did eggs that died late (LD), whereas eggs containing early dead (ED) embryos exhibited the greatest weight loss. The pore concentration at the large end of each egg was greatest in H eggs when compared with all other types. The pore concentration at the equator was greatest in H eggs and least in the eggs of the ED embryos. All other egg types lay statistically between these two types with regard to equator porosity. The small end pore concentration was similar in H, INF, and LD eggs and in the LD, PIP, and ED eggs. The least number was exhibited by the ED eggs and most by the H eggs. The thinnest shells at the small end were exhibited by H eggs, whereas thicker small end shells were exhibited by ED, LD, and PIP egg types. No differences were observed at the large end or equator. The data suggest that ED eggs exhibit excessive weight loss even though shell porosity was lower and shell thickness was similar to other egg types. This suggests that some functional component of the egg such as the shell membrane or albumen may contribute to this excessive weight loss. A similar statement can be made for LD eggs, which experienced greater weight loss through 15 d than did PIP or H eggs.

“…As amniotes and endothermic organisms, avian embryos are also likely to develop in a hypoxic environment, as the oxygen permeability through the shell and the underlying membranes is extremely low in the first few days of incubation (Kayar et al, 1981). In both mouse and chick embryos, the heart starts beating at the 10-somite stage, which is at 8.5 dpc in mouse and Hamburger and Hamilton (HH) stage 10 in chick (Hamburger and Hamilton, 1951); however, functional blood circulation begins only a day later (Coffin and Poole, 1988;Kayar et al, 1981;le Noble et al, 2004;McGrath et al, 2003;Meuer and Baumann, 1987;Nanǩa et al, 2006). At the subcellular level, oxygen consumption is reflected in the morphology of mitochondria.…”

Hypoxia promotes production of neural crest cells in the embryonic head

et al. 2016

Hypoxia is encountered in either pathological or physiological conditions, the latter of which is seen in amniote embryos prior to the commencement of a functional blood circulation. During the hypoxic stage, a large number of neural crest cells arise from the head neural tube by epithelial-to-mesenchymal transition (EMT). As EMTlike cancer dissemination can be promoted by hypoxia, we investigated whether hypoxia contributes to embryonic EMT. Using chick embryos, we show that the hypoxic cellular response, mediated by hypoxia-inducible factor (HIF)-1α, is required to produce a sufficient number of neural crest cells. Among the genes that are involved in neural crest cell development, some genes are more sensitive to hypoxia than others, demonstrating that the effect of hypoxia is gene specific. Once blood circulation becomes fully functional, the embryonic head no longer produces neural crest cells in vivo, despite the capability to do so in a hypoxia-mimicking condition in vitro, suggesting that the oxygen supply helps to stop emigration of neural crest cells in the head. These results highlight the importance of hypoxia in normal embryonic development.

“…Several studies have shown that a 10-fold increase in oxygen permeability of the integument (the porous calcific shell lined on its inner surface with fibrous membranes) occurs 22% of the way through incubation of several species of birds (Tullett and Board, 1976;Kayar et al, 1981;Seymour and Piiper, 1988). Attempts to interpret this observation have caused questions about the role of water, either in or between fibers of the shell membranes, on the diffusion of oxygen through the interstitial spaces.…”

“…Attempts to interpret this observation have caused questions about the role of water, either in or between fibers of the shell membranes, on the diffusion of oxygen through the interstitial spaces. Kayar et al (1981) and Robel et al (1986) was due to increased inner membrane permeability. The increased permeability was thought to be due to evaporation causing a layer of water in the inner membrane to be reduced in thickness from about 63 to .6 urn.…”

Membranes from fertile and infertile turkey eggs were examined during incubation to determine the content of Ca, Mg, Na, and K. The Ca concentration in shell membranes of fertile eggs increased (K.05) as compared with that in infertile eggs, but concentrations of Mg, Na, and K in shell membranes of fertile eggs declined (P£.05) as compared with those in infertile eggshell membranes. The data suggest a possible role for some minerals in regulating functional eggshell properties. (
