First it was the charge that women in Woo Suk Hwang?s lab had donated their eggs for research, a clear violation of ethical standards. Then came his admission that photographs in a Science paper he published last year on stem cells cloned from human volunteers were phony, which led to a retraction. But when a panel at Seoul National University ruled last week that not just the pictures but much of the data in the Science paper had been faked as well, Woo Suk Hwang, South Korea?s cloning superstar, had to resign...
...terrible setback for South Korean science and for a nation that has been hoping to become the world leader in therapeutic cloning technology-that is, the idea of using a patient?s own cells to grow replacement parts for failing tissue. And for Hwang himself, who seemed to be leaving other scientists in the dust, things have gone from bad to worse. He?s still insisting that two of the 17 human stem-cell lines he says he created through cloning are legitimate, but the university is looking into those as well-and sifting through his data on Snuppy, which...
...Hwang?s disgrace shouldn?t be used as an excuse to pour scorn on the idea of therapeutic cloning itself. Ambition and pride are a danger in any high-risk, high-reward area of science, but therapeutic cloning is so promising that it needs to be pursued regardless. The potential medical advantages are enormous: by cloning a patient?s own cells to create stem cells, then coaxing those stem cells to become new pancreatic, brain, spinal cord or heart tissue, for example, it?s conceivable that a victim of Parkinson?s, Alzheimer?s, diabetes, paralysis or heart disease could shore...
...last week, Hwang's colleague Roh Sung Il, who collaborated on the groundbreaking study, alleged that Hwang had faked research data so that it appeared more stem-cell lines had been produced than was actually the case. In statements to the media, Roh even questioned whether Hwang had created any stem-cell lines at all. In a nationally televised press conference the next day, Hwang denied the accusations, saying he would retest five remaining frozen stem-cell lines to prove his cloning techniques were authentic-at the same time acknowledging that the other six colonies had been contaminated...
...Hwang, who this year became the first scientist to clone a dog, was already under fire after being forced to apologize in November for ethical lapses in his work. It was revealed that many of the eggs used to produce human stem cells in his first breakthrough work at the start of 2004 had come from two of his own researchers or from donors who had been paid-both serious breaches of medical ethics. But it seems that Hwang still has one last chance to vindicate himself: by proving that his frozen stem-cell colonies are authentic and that...
