Cell Movement patterns during gastrulation in the chick are controlled by positive and negative chemotaxis mediated by FGF4 and FGF8 [PDF]

open access: yes, 2002
During gastrulation in amniotes, epiblast cells ingress through the primitive streak and migrate away to form endodermal, mesodermal, and extraembryonic structures.

Measurement of junctional tension in epithelial cells at the onset of primitive streak formation in the chick embryo via non-destructive optical manipulation [PDF]

open access: yes, 2020
Directional cell intercalations of epithelial cells during gastrulation has in several organisms been shown to be associated with a planar cell polarity in the organisation of the actin-myosin cytoskeleton and is postulated to reflect directional tension

Influence of In Ovo Leptin Injection into Yolk Sac on Embryo Development, Blood Biochemical Parameters and Lipid Metabolism of Broiler Chicks during Early Post-Hatching Period

open access: yesYüzüncü Yıl Üniversitesi Tarim Bilimleri Dergisi, 2022
The study aimed to investigate the effect of in ovo (IO) leptin injection on yolk sac leptin concentration, embryo development, blood lipid metabolism, and biochemical parameters of broiler chicks during the early post-hatching period. Hatching eggs were

A new oxidative stress model, 2,2-azobis(2-amidinopropane) dihydrochloride induces cardiovascular damages in chicken embryo. [PDF]

open access: yesPLoS ONE, 2013
It is now well established that the developing embryo is very sensitive to oxidative stress, which is a contributing factor to pregnancy-related disorders.

Controlled-rearing studies of newborn chicks and deep neural networks [PDF]

open access: yesarXiv, 2021
Convolutional neural networks (CNNs) can now achieve human-level performance on challenging object recognition tasks. CNNs are also the leading quantitative models in terms of predicting neural and behavioral responses in visual recognition tasks. However, there is a widely accepted critique of CNN models: unlike newborn animals, which learn rapidly ...

A vertebrate crossveinless 2 homologue modulates BMP activity and neural crest cell migration [PDF]

open access: yes, 2004
Previous work has revealed that proteins that bind to bone morphogenetic proteins (BMPs) and inhibit their signalling have a crucial role in the spatial and temporal regulation of cell differentiation and cell migration by BMPs.

Effects of Different Fertility Rates on Chick Quality and Hatching Parameters in Hatching Eggs

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2014
This study was conducted to investigate the hatching parameters differences between the hatching eggs which were controlled or not for fertility at 18th day of embryo development in the hatchery unit.

A newborn embodied Turing test for view-invariant object recognition [PDF]

open access: yesarXiv, 2023
Recent progress in artificial intelligence has renewed interest in building machines that learn like animals. Almost all of the work comparing learning across biological and artificial systems comes from studies where animals and machines received different training data, obscuring whether differences between animals and machines emerged from ...

Chorioallantoic membrane assay as model for angiogenesis in tissue engineering : focus on stem cells [PDF]

open access: yes, 2020
Tissue engineering aims to structurally and functionally regenerate damaged tissues, which requires the formation of new blood vessels that supply oxygen and nutrients by the process of angiogenesis.

Genetic Characterization of Human Rabies Vaccine Strain in Japan and Rabies Viruses Related to Vaccine Development from 1940s to 1980s

open access: yesViruses, 2022
The rabies virus is widely distributed and vaccines are an important strategy to prevent its spread. The whole-genome sequences of rabies strains in relation to vaccine development provide essential information to maintain vaccine quality and develop new
