In 2012, John B. Gurdon and Shinya Yamakana were awarded the Nobel Prize in medicine for discovering that adult cells can be reprogrammed into pluripotent ones (iPS); the cells obtained are capable of behaving in a similar way to embryonic stem cells, and hence have enormous potential for regenerative medicine.
However, although there are many research groups around the world studying this process, it is still not completely understood, it is not totally efficient, and it is not safe enough to be used as the basis for a new cell therapy.
