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 ...
In a 2004 paper published in the journal Nature, the International Chicken Genome Sequencing Consortium found that although a chicken doesn't have as much DNA as a human, it has about the same ...
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 ...
According to the National Chicken Council, the birds head to market at an average of over 6 pounds in just 47 days. Back in the 50's, it would take 70 days for them to reach half that weight.

[16] Mammals usually copulate in a dorso-ventral posture, although some primate species copulate in a ventro-vental posture. [17] [18] Most mammals possess a vomeronasal organ that is involved in pheromone detection, including sex pheromones. [19]
