British scientists have genetically manipulated 500 laying hens to produce eggs rich in proteins useful for making different drugs against diseases such as cancer or multiple sclerosis. The manipulations have been made at the Roslin Institute in Edinburgh, where the famous Dolly sheep was born.
The introduction of human genes that produce proteins to the laying species ISA Brown can last for several generations, so that a mass supply approach can be made to pharmaceutical laboratories with a much lower product cost. At the moment there are five generations of chickens and the last ones maintain a high protein production in their eggs.
The valued proteins are found in the egg white which will be easily extracted for the elaboration of drugs.
A step forward in science to applaud. Those of us who like to eat would love to have the eggs directly consumed that cure diseases, it would be a good therapy too, don't you think?
