STEM CELLS Before admitting to ethical lapses last week, the same Korean researcher who created Snuppy the cloned puppy (see "Cloning") shocked Western scientists by producing 11 custom-made human-stem-cell lines from the cloned skin cells of individual patients. The labs' procedure was surprisingly efficient; Woo Suk Hwang and his team needed on average only 17 human eggs to grow each of the cell lines (in contrast to the 242 eggs they needed to make a single stem-cell line just 15 months earlier). Research like this may someday lead to treatments for a wide range of disorders...
CLONING Scientists had cloned sheep, pigs, cattle, mice, rabbits, horses and cats but, until this year, never a dog. Man's best friend, it turns out, is extremely difficult to duplicate. It was Woo Suk Hwang and his team at Seoul National University who finally succeeded in turning a single cell from the ear of an Afghan hound into a genetically identical puppy. Hwang was back in the news last week when he admitted lying about the source of some of the human eggs used in an earlier stem-cell experiment. Nevertheless, many scientists suspect the techniques Hwang perfected...
...Hwang Woo Suk, South Korea's pioneering stem-cell researcher, success comes from a willingness to work harder than anyone else. But his researchers may have taken their dedication a step too far. Last Thursday, after repeated denials, Hwang admitted that two of his junior lab workers had donated their eggs?a critical component for embryonic-stem-cell studies?for his research, and that an associate had paid other women for their eggs in 2002 and 2003. "Being too focused on scientific development, I may not have seen all the ethical issues related to my research," a grim Hwang said...
...professor of medical science at the Catholic University of Korea in Seoul and a member of the Korean Bioethics Association, described Korean reaction as "very emotional and very supportive" of Hwang's research: "They are enraged at the idea that ethical concerns could block scientific advances." She said government and media are confusing the public by obscuring the real issue-that "Korean science has lost credibility in the world." Seoul National University's oversight committee announced that its investigation showed no ethical or legal problems, she notes, but "Korea's representative scientist just turned out to be a liar...
...past year, Hwang also refined his human-cell-cloning process to yield the first stem cells from patients with diseases, bringing medicine a step closer to the possibility of curing illnesses from Alzheimer's to diabetes with a patient's own rejection-proof tissues. Now his new lab will try to duplicate that scientific winning streak without...
