A team of Boston and Japanese researchers stunned the scientific world Wednesday by revealing a remarkably simple and unexpected way to create stem cells able to give rise to any tissue in the body. Charles Vacanti, the Vandam/Covino Professor of Anaesthesia and head of the Department of Anesthesia at Brigham and Women’s Hospital, led the research. Douglas Melton, the Xander University Professor of Stem Cell and Regenerative Biology and co-director of the Harvard Stem Cell Institute, and George Q. Daley, professor of biological chemistry and molecular pharmacology at Boston Children’s Hospital, are also quoted.
