The chicken embryo is a unique model that overcomes many limitations to studying the biology of cancer in vivo. The chorioallantoic membrane (CAM), a well-vascularized extra-embryonic tissue located underneath the eggshell, has a successful history as a biological platform for the molecular analysis of cancer including viral oncogenesis, [8] carcinogenesis, [9] tumor xenografting, [1] [10] [11 ...
It is now clear that the bursa is the primary site of B cell lymphopoeisis and that avian B cell development has some unique properties compared to human or mouse models. [11] Almost all the B cell progenitors in the bursa of 4-day-old chickens express IgM on their cell surface. Studies have shown that B cells of 4– to 8-week-old birds are ...
The chicken (Gallus gallus domesticus) is a large and round short-winged bird, domesticated from the red junglefowl of Southeast Asia around 8,000 years ago. Most chickens are raised for food, providing meat and eggs; others are kept as pets [1] or for cockfighting.
When it came to the genes that program our reproductive and immune systems, the chicken genes were less similar. To put that 60% in perspective, chimpanzees, our closest living evolutionary ...
Landmark studies in chickens demonstrated that individual cells in somatic tissues could retain their sex identity regardless of the hormonal milieu, providing compelling evidence for CASI. This finding contrasted sharply with mammalian models, where hormonal influences were thought to dominate sexual differentiation.
A model organism is a non-human species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the model organism will provide insight into the workings of other organisms.

Chickens were one of the domesticated animals carried with the sea-borne Austronesian migrations into Taiwan, Island Southeast Asia, Island Melanesia, Madagascar, and the Pacific Islands; starting from around 3500 to 2500 BC. [25] [26] By 2000 BC, chickens seem to have reached the Indus Valley and 250 years later, they arrived in Egypt. They ...
