Investigation of chicken embryo metabolism and substrate utilization during later development
… adaptations and substrate utilization during chicken embryo development and to determine the influence of breeder age and egg size on embryonic growth and metabolism during development (embryonic day 11 to posthatch day 1). In Study One, for both small (n = 60, 53.2 ± 1.04 g) and large (n = …

Direct Effect of Glucocorticoids on the Developing Cardiovascular System: Studies in the Chicken Embryo
… effect on the fetal cardiovascular system. The chicken embryo model was used to establish a clinically relevant glucocorticoid treatment at two thirds of development, without compounding influence of maternal or placental physiology, such that the direct effect of glucocorticoid exposure on the …

Potassium and Sodium Movements Related to Growth State and Malignant Transformation in Cultured Chicken Embryo Cells
… Rous sarcoma virus-transformed (RSV-transformed) chicken embryo fibroblasts and following serum stimulation of quiescent, density-inhibited chicken embryo fibroblasts. Active potassium transport and the associated specific ouabain binding were shown to be dependent on the cellular growth state but …

Hematocrit, hematocrit Regulation and its effect on oxygen consumption in the late stage chicken embryo (Gallus domesticus).
… have the potential to affect developing embryos. To examine the ability of chicken embryos at day 15 to regulate hematocrit, they were subjected to either repeated saline injections (5% of total blood volume) or repeated blood removal (5% of total blood volume). Embryos showed an ability …

Effect of flourophenylalanine on the replication of avian infectious brohchitis and Newcastle disease viruses in chicken embryo kidney cells

The role of prostaglandins, nitric oxide and oxygen in the ductus arteriosi of the pre-term chicken embryo (Gallus domesticus).
The chicken ductus arteriosi (DA) are two embryonic blood vessels that shunt blood away from the non-ventilated lungs and towards the body and chorioallantoic membrane. I show that prostaglandins have a diminished role in maintaining chicken DA patency and nitric oxide inhibits oxygen induced …

Characterisation and functional analysis of the chicken microphthalmia gene
Despite the fact that the chicken embryo is a model system for developmental biologists, comparatively little is known about the regulation of avian melanogenesis. There has only been one report of the characterisation of the chicken tyrosinase gene promoter, and only one full-length chicken …

Presentation of Recombinant Proteins in Modified Vaccinia Virus Ankara Extracellular Enveloped Virions
… it could be shown that MVA infection in primary chicken embryo fibroblasts results in the production of enveloped viruses, but strikingly most of these were not released into the culture medium but remained attached to the plasma membrane. The results also showed that the replication competent …

Effect of Lipid Modification on Transformation - Associated Properties and Viral Membrane Assembly
… acid composition of the cellular membranes in chicken embryo fibroblasts. We have used this technique to study the effect of lipid modification on various parameters associated with transformation in tissue culture. Lipid supplementation had a variety of effects on cellular morphology, …

Functional Characterization of the Avian Inflammatory Mediators Nod1, MIF and IL-22
… anti-microbial peptides. A candidate sequence of chicken Nod1 (ChNod1) was identified with no current evidence of ChNod2. Stimulation of transiently overexpressed ChNod1 and its mutants with mammalian Nod-specific ligands was not conclusive of the function of ChNod1 most likely due to …

Characterization of the Surface Proteins of the Anatid herpesvirus
… Culture Collection No. VR684) was propagated in chicken embryo fibroblasts and purified by differential and buoyant density sedimentation through thtough sucrose gradients. A total of 17 putative virus proteins were consistently identified in both polyacrylamide gel electrophoresis and …

The Cytoplasmic Domain of Membrane-type 1 Matrix Metalloproteinase is Required for its Survival-Promoting, but not its Migration-Promoting Function in MCF-7 Breast Cancer Cells
… upon serum starvation. MT1-MMP expression in a chicken embryo tumour model resulted in vascularization of MCF-7 tumours; a phenotype that was partially maintained following expression of MT1-MMP CD variants. These results suggest that the CD regulates MT1-MMP localization in a manner required …

Development of Cardiovascular Regulation in Embryos of the Domestic Fowl (Gallus Gallus), with a Partial Comparison to Embryos of the Desert Tortoise (Gopherus Agassizii)
… basic cardiovascular regulation in the chicken embryo to provided the needed information for it's use an alternative to the fetal lamb. Developing chicken embryos rely on both alpha and beta adrenergic tones to maintain normal heart rate and arterial blood pressure during incubation. …

A Role for RAS in V-CRK Transformation
… of cellular phosphotyrosine as it transforms chicken embryo fibroblasts (CEF). Because of this similarity to v-Src transformation and EGF receptor (EGFR) stimulation, signalling pathways that might be activated in v-Crk transformed cells were investigated by analogy to pathways utilized by …

Modulation of the angiogenic potential in collagen matrices by immobilisation of heparin and loading with vascular endothelial growth factor
… implanted on the chorioallantoic membrane of the chicken embryo and in subcutaneous tissue of the rat. Specimens were explanted after varying periods of implantation, the number of capillaries in the CAM and hemoglobin content in the specimens were evaluated: heparinized collagen matrices loaded …

The Generation of a Candidate Axial Precursor in Three Dimensional Aggregates of Mouse Embryonic Stem Cells
Textbook accounts of vertebrate embryonic development have been based largely upon experiments on amphibian embryos, which have shown that the tissues of the trunk and tail are organised from distinct precursors that existed during gastrulation. In the mouse and chick, however, retrospective clonal …

Dynamics of Alpha5 Integrin, Paxillin, and Alpha-Actinin During Formation and Disassembly of Adhesions in Migratory Cells
… cell retraction. Observing cell migration in a chicken embryo slice system has allowed comparison of cell migration within an organism to the process commonly studied in tissue culture cells. Cell migration in vivo is similar to the in vitro process, except that each step is exaggerated in a …

Deciphering the regulatory code driving neural crest evolution and development
… cells are a unique feature of vertebrates. This embryonic cell population is multipotent, giving rise to many structures including peripheral neurons. The sea lamprey, Petromyzon marinus, is at the base of the vertebrate lineage and offers an ideal model for the ancestral neural crest. …

Ontogeny and biological function of epithelial cells in the chicken yolk sac and small intestine
The chicken yolk sac and small intestine are connected through the yolk stalk and share many biological similarities. During the embryonic stage, the extra-embryonic yolk sac helps the embryo to absorb nutrients primarily in the last two weeks of incubation. The chicken yolk sac physically moves …
