South Korean cloning pioneer Hwang Woo Suk admitted last month that his lab accepted human egg donations from two of its own researchers, a violation of scientific ethics. Yet Hwang's televised apology stirred South Koreans and prompted many women to volunteer their own eggs. Hwang tells TIME's Anthony Spaeth via e-mail that his research must continue...
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...
...Hwang. His lab produced a series of major steps forward in 2005, including the creation of the world's first cloned dog, Snuppy, by a process that was named by TIME earlier this month as the Invention of the Year. At a website called "I Love Hwang Woo Suk," decorated with a Korean flag and pictures of Hwang with Snuppy, many members have posted messages saying they would love to donate eggs. The founder of the site staged a 10-hour, one-man demonstration in front off MBC's offices Thursday, holding a candle as he stood in a cardboard...
