Reprogrammed cells trigger immune reactions in mice

Reprogrammed cells trigger immune reactions in mice : Nature News: 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 Nature. It will shake up the regenerative-medicine field, because until now, most scientists have assumed that reprogrammed cells made from an individual's own tissue could be safely transplanted back into the same person.
