Reprogrammed cells trigger immune reactions in mice

Cells that have been reprogrammed to grow into different types of tissue might be rejected by the body — even when they are transplanted into the individual from whom they are made, researchers report in a study published today in Nature1.The study was led by Yang Xu, a molecular biologist at the University of California, San Diego. It will shake up the regenerative-medicine field, because until now, most scientists have assumed that reprogrammed cells made from an individuals own tissue could be safely transplanted back into the same person.
