Researchers said they had shown cloning can work as a source of grow-your-own transplants, by implanting into cattle cloned cells that formed functioning kidney-like organs and working heart tissue.



The cattle’s immune systems showed no sign of rejecting the transplanted cloned tissue, said the team from Children’s Hospital in Boston and Advanced Cell Technology in nearby Worcester, Massachusetts.



The researchers said their experiment, published in the June issue of the journal Nature Biotechnology, should put to rest criticism that therapeutic cloning will not work. More here.
