Engineered chickens make cancer drugs

ChickenScientists create genetically engineered chicken that produces cancer drugs in its eggs.

The chickens produce the cancer drugs in their egg whites, the team at the Roslin Biocentre in Edinburgh reported.

They used a virus to infect very early chicken embryos. The virus inserted the genetic material into the DNA of chick embryos in newly laid eggs.

The researchers hatched these chicks and found the male chicks who had indeed incorporated the new DNA in their semen.

These cockerels were then bred with normal hens and they screened the resulting chicks to see which ones still carried the two new genes. The researchers have now bred several hundred chickens that can produce the desired proteins.
