SCIENTISTS are to grow a human donor organ in an animal for the first time.
They hope to develop a pancreas inside a sheep.
If successful it will give hope to thousands of patients awaiting organ transplants.
The experts have already created a sheep embryo containing human stem cells and used gene editing to produce a live sheep without a pancreas.
Prof Pablo Ross, of the University of California, told the American Association for the Advancement of Science: “What we expect is the human cells will be able to grow that organ.
“There is a huge shortage of organs and if this is successful we will have a source.” The first transplant could be in five years.
There are 6,500 patients on the transplant waiting list, nearly 500 of whom die each year.
But London genetics expert Prof Robin Lovell-Badge fears the process will not work.
He said: “The organs could not be used for transplants into humans without triggering the immune system to reject them.”
