... by the extraembryonic membranes, but it is unknown if the extraembryonic membranes also respond to maternal glucocorticoids in a way comparable to the placenta. In this study, we quantified the expression of acyl-CoA thioesterase 13 ( Acot13 ) as an initial marker of the membrane's response to corticosterone in chicken...

... acids, fatty acids, cellular ketones, lipids, and thioesters, which have also been proved in the present study. However, chickens are important oviparous animals whose main nutrients are obtained from the vitellicle during the embryonic period and the first 3 days after birth ( Noy et al., 1996 ), thus...

...B. M. Duggan; P. M. Hocking; D. N. Clements ABSTRACT Genetic selection for increased growth rate and muscle mass in broiler chickens has been accompanied by mobility issues and poor gait. There are concerns that the Pekin duck, which is on a similar selection trajectory (for production traits...

...John N. Maina; Sikiru A. Jimoh Summary Structural failure of blood–gas barrier (BGB) and epithelial–epithelial cell connections (EECCs) in different vascular regions of the exchange tissue of the lung was studied in rested and exercised chickens. The number of red blood cells (nRBCs) was counted...

...Ana De Melo Bernardo; Kaylee Sprenkels; Gabriela Rodrigues; Toshiaki Noce; Susana M. Chuva De Sousa Lopes Summary During gastrulation, chicken primordial germ cells (PGCs) are present in an extraembryonic region of the embryo from where they migrate towards the genital ridges. This is also observed...

... factors that regulate this process have not been elucidated. Here we show that a LIM-homeobox gene, Lhx1 , normally expressed in the proximal region of the nascent OV, induces a second neurosensory retina formation from the outer pigmented retina when overexpressed in the chicken OV. Lhx2 , another LIM...
