This time, adult stem cells taken from dead donors restored sight in the living. It turned out that the actual healing was accomplished by the patients’ own cells, not those that were implanted. Note the potential implications: Nadey Hakim, a consultant surgeon at St Mary’s Hospital, London, said that it was likely that such action could be mimicked in other organs, thus reducing the need for organ transplants. “The hope is that stem cells will one day be used to generate large quantities of cells and tissues and possibly entire organs damaged by disease and injury. It is a dream.”
Shhh. Don’t tell the New York Times.
