GM chickens that can lay eggs with anti-cancer proteins made
Edinburgh University's Roslin Institute researchers have genetically modified (GM) chickens to lay eggs that contain proteins that are used in drugs to treat some cancers and arthritis. The chickens were modified to produce human protein IFNalpha2a which has anti-cancer effects. "Production (of drugs) from chickens can cost anywhere from 10 to 100 times less than the factories," a researcher said.
