research team in Georgia believes chickens are ideal candidates
to produce human proteins. Other animals, like sheep and goats,
have been genetically engineered to produce human proteins in their
milk. But the time it takes for a genetically engineered animal
to mature and produce milk is much longer than the time it takes
for a GE chicken to start laying eggs.
By the Numbers
An average chicken will lay around 330 eggs a year. All of those
eggs could contain important human proteins if they came from a
GE chicken. Human drugs that might be made using eggs include serum
albumin, which is used to treat blood loss, and antibodies, used
to treat infections and cancer.
