Meeting embryonic requirements of broilers throughout incubation: a review [PDF]
, 2010 During incubation of chicken embryos, environmental conditions, such as temperature, relative humidity, and CO2 concentration, must be controlled to meet embryonic requirements that change during the different phases of embryonic development.

Origins of the avian neural crest: the role of neural plate-epidermal interactions [PDF]
, 1995 We have investigated the lineage and tissue interactions that result in avian neural crest cell formation from the ectoderm. Presumptive neural plate was grafted adjacent to non-neural ectoderm in whole embryo culture to examine the role of tissue ...

FGF signaling controls somite boundary position and regulates segmentation clock control of spatiotemporal Hox gene activation [PDF]
, 2001 Vertebrate segmentation requires a molecular oscillator, the segmentation clock, acting in presomitic mesoderm (PSM) cells to set the pace at which segmental boundaries are laid down. However, the signals that position each boundary remain unclear. Here,

Terrestrial Planets Formation around Circumbinary Habitable Zone: Inward Migration in the Planetesimal Swarm [PDF]
, 2012 According to the core accretion theory, circumbinary embryos can form only beyond a critical semimajor axis (CSMA). However, due to the relatively high density of solid materials in the inner disk, significant amount of small planetesimals must exist in the inner zone when embryos were forming outside this CSMA.

Insulin Hypoglycemia in Chick Embryos.
Experimental Biology and Medicine, 1948 Landauer1, 2 has found that certain morphological abnormalities may be produced by injecting insulin into the yolk of 0-5-day chick embryos. In the course of an investigation into the carbohydrate metabolism of insulin-treated embryos we have found that a persistent hypoglycemia is produced by insulin applied in this manner.

Effect of administration gamma-amino butyric acid on physiological performance of broiler chicks [PDF]
arXiv, 2020 This experiment was conducted to study the effect of administration {\gamma}-amino butyric acid (GABA) on physiology performance of broiler chicks. The following treatments were used: T1:control treatment, T2: the birds were administration 0.2ml 0.4% GABA solution daily, T3: the birds were administration 0.2ml 0.5% GABA solution daily and T4: the birds

Endocrine cells in atresic chick embryo intestine: histochemical and immunohistochemical study
European Journal of Histochemistry, 2009 Intestinal motility disorders are an important problem in the postoperative management of patients with intestinal atresia. Intestinal motility could be initiated by luminal factors that activate intrinsic and extrinsic primary afferent nerves involved ...
