Depletion of Primordial Germ Cells (PGCs) by X-irradiation to Extraembryonic Region of Chicken Embryos and Expression of Xenotransplanted Quail PGCs

The Journal of Poultry Science, 2009
The generation of germline chimeras by the transfer of primordial germ cells (PGCs) requires incorporation of the PGCs of the donor into the gonadal tissue of the recipient embryo.

ATZ‐1 promotes DNA replication efficiency to maintain normal meiotic function

FEBS Open Bio, EarlyView.
Absence of ATZ‐1 interferes with meiotic DNA replication and cell cycle function via CHK‐1. This causes downstream defects associated with DNA damage and genomic integrity. Taken together, this study suggests that ATZ‐1 influences DNA replication efficiency and cell cycle function to maintain normal meiotic function.

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

FEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Proteomics reveals changes in hepatic proteins during chicken embryonic development: an alternative model to study human obesity

BMC Genomics, 2018
Background Chicken embryos are widely used as a model for studies of obesity; however, no detailed information is available about the dynamic changes of proteins during the regulation of adipose biology and metabolism.

Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective PIGM encodes a critical enzyme in the glycosylphosphatidylinositol (GPI)‐anchor biosynthesis pathway. While promoter‐region mutations in PIGM have been associated with a relatively mild phenotype characterized by portal vein thrombosis and absence seizures, recent evidence suggests that coding‐region mutations result in a more severe

Transcriptional Innate Immune Response of the Developing Chicken Embryo to Newcastle Disease Virus Infection

Frontiers in Genetics, 2018
Traditional approaches to assess the immune response of chickens to infection are through animal trials, which are expensive, require enhanced biosecurity, compromise welfare, and are frequently influenced by confounding variables.

Chondrodystrophia in chicken embryos.

Experimental Biology and Medicine, 1926
During the routine examination of chick embryos which had died during incubation, we found in 1923 several embryos exhibiting a striking abnormality resembling the condition known in mammals as Chondrodystrophia foetais (Kaufman).∗ As far as our knowledge of the literature reaches, chondrodystrophia is here reported for the first time in bird embryos ...

Visualization of chicken embryo heart motion [PDF]

Computer Methods in Biomechanics and Biomedical Engineering: Imaging & Visualization, 2016
We present a geometric surface parameterisation algorithm and multiple visualisation techniques (cross-sectional area and shape change, peristaltic motion, stress/strain, volume change, surface curvature change several visualisation techniques) adapted to the problem of understanding the 4D peristaltic-like motion of the outflow tract (OFT) in an ...

Innate Immune Reprogramming Mediated by Endogenous Retroelement Dysregulation Drives Multiple Sclerosis Progression

Annals of Clinical and Translational Neurology, EarlyView.
Epigenetic reprogramming in hematopoietic stem and progenitor cells (HSPCs) and downstream myeloid cells, mediated by H3.3 downregulation and endogenous retroelement (ERE) overexpression, contributes to the progression of multiple sclerosis (MS). ABSTRACT Background Skewed myelopoiesis in the bone marrow has been identified as a key driver of multiple ...

CELL BLOCKADE IN NEWCASTLE DISEASE OF CHICKENS AND CHICKEN EMBRYOS [PDF]

Journal of Experimental Medicine, 1949
The problem of cell blockade or interference has been studied using Newcastle disease of chickens as a model. Embryos may be protected against the uniformly lethal effect of the virus by previous inoculation with ultraviolet-irradiated virus. It was necessary to use 0.5 to 1 mg.
