Scientists using this method seek to persuade the cell to "forget" its current status and go back to the original stem cell state it was in during its time in the embryo.
The first solid evidence implicating stem cells in cancer came in the early 1990s when John Dick, a stem cell researcher at the University of Toronto, developed a method for transplanting cancerous human bone marrow cells into mice.
The new study involves a complex method that requires women to donate eggs, and a demanding manipulation of cell components on a tiny scale, Daley said.
