...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...
...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 to clone...
...study originally stated, all been unpaid volunteers. After that, he said, they will await the reports from the investigations conducted by the South Korean Ministry of Health and by Seoul National University, where Hwang is a faculty member, and where he will continue to do stem cell research, to determine whether the integrity of Hwang's results were compromised in any way. So far, that does not seem to be the case. "We have no reason to doubt the scientific validity of the study," says Kennedy...
...South Korea, where he's something of a national hero. Earlier this week, the female head of an info-tech consulting company, along with 11 other business people, a lawmaker and a female comedian, set up a non-profit foundation to encourage women to donate eggs to stem cell research. Eighty women have signed up so far, a foundation spokesperson said. There has been a backlash against broadcaster MBC for airing a program this week that highlighted the ethical questions about how Hwang obtained eggs. Koreans have called companies that ran commercials during the weekly documentary's time slot...
...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...
