...welcome as that change will be, it may be less urgent now - owing primarily to the work of scientists like Melton. While embryonic stem cells remain the gold standard for any treatments that find their way into the clinic, newer techniques using the next-generation stem cells may soon surpass the older ones...
...decision sent some leading scientists abroad, to Britain, Singapore and China, where the governments were more receptive to their work. Others who stayed behind but lacked private funding shifted their attention from embryos to the less versatile adult stem cells. Federally backed scientists, like Melton, who continued embryonic work were forced to adopt a byzantine system of labeling and cataloging their cell cultures and equipment so that government money was not used to grow forbidden cells - and government microscopes were not even used to look at them...
Those days may soon be over. Barack Obama campaigned on a promise to lift the research ban and support "responsible oversight" of the stem-cell field. For scientists, that means "we can stop the silliness," says Melton...
...remained there for his Ph.D. work, studying under Sir John Gurdon - the first to clone a frog. At Harvard, Melton teaches a frequently oversubscribed undergraduate course on science and ethics, in which he uses his keen sense of logic to provoke. When the class discussed the morality of embryonic-stem-cell research, Melton invited Richard Doerflinger of the U.S. Conference of Catholic Bishops to present arguments against the field. Melton asked Doerflinger if he considered a day-old embryo and a 6-year-old to be moral equivalents; when Doerflinger responded yes, Melton countered by asking why society accepts...
Clearly, Melton does not shrink from a fight. As Washington's squeeze on stem-cell research tightened in the early part of this decade, he decided to take action, providing life support for what remained of the U.S. stem-cell community. Not convinced that an entire field could make much progress relying on a few dozen cell lines of questionable quality, in 2004 he used funds HSCI receives from the Juvenile Diabetes Research Foundation and the Howard Hughes Medical Institute, as well as from Harvard alumni, and developed a more streamlined method for generating stem-cell lines from embryos...
