An Aberrant Parthenogenetic Chicken Embryo

Poultry Science, 1972
Abstract A virgin Dark Cornish hen laid an egg which began to develop parthenogenetically. The embryo thus formed was harvested for chromosomal analysis after twenty-two hours of incubation. A unique translocation between one member of each of the largest and third largest pairs of chromosomes was found in all thirty-seven metaphase cells observed ...

Micro-magnetic resonance imaging study of live quail embryos during embryonic development [PDF]

, 2011
Eggs containing live Japanese quail embryos were imaged using micro-magnetic resonance imaging (μMRI) at 24-h intervals from Day 0 to 8, the period during which the main body axis is being laid down and organogenesis is taking place.

Shared mechanism of teratogenicity of anti-angiogenic drugs identified in the chicken embryo model

Scientific Reports, 2016
Angiogenesis, the formation of new blood vessels, is essential for tumor growth, stabilization and progression. Angiogenesis inhibitors are now widely used in the clinic; however, there are relatively few published studies on the mechanism of their ...
