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...
Stem-cell scientist Hwang Woo Suk, whose groundbreaking cloning of human embryos thrust South Korea to the forefront of bioscience research, is fighting for his professional life in a controversy that is degenerating into one of the biggest scientific scandals in years...
...Hwang and his team of researchers at Seoul National University stunned the medical community in May when, in a study published in the U.S. journal Science, he reported that he had successfully produced tailor-made stem cells from 11 cloned human embryos-an unprecedented feat. Though controversial, Hwang's research was hailed as a breakthrough because it appeared to move scientists a step closer to being able to treat a variety of afflictions, from spinal-cord injuries to Alzheimer's, by using a patient's own dna to grow perfectly matched tissue to restore defective or damaged organs...
...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...
