Today, eggs are indispensable food products. At the same time, at least in terms of chickens, eggs are very important intergenerational connections. As we can see, when eggs are hatched under proper conditions, they provide every components that generate blood and bones as well as to nurture embryo to healthy chick. Yet, despite how long eggs have been studied, there are still many unexplained biological secrets in this wonderful food and genetic source.
Research to forecast 21st century egg use technology, the chicken genome analysis, was completed in December 2004, culminating in the announcement of the entire base sequence. In August 2005, Origen Therapeutics in the United States created transgenic chickens from a chicken’s Embryo Stem cell and succeeded in producing human monoclonal antibodies in these eggs. In Japan, a method was developed to create transgenic chickens by introducing a retroviral vector to the embryo of 2 day fortilized eggs.
By using these latest technologies, we may be able to see chickens that are resistant to influenza viruses and able to create eggs eliminating allergen proteins. Furthermore, transgenic chickens will make it possible to produce eggs that include protein and peptidergic medicines.
