3、e pressure on stem cell pioneer Woo Suk Hwang over the way he obtained human eggs for his research is intensifying-particularly in South Korea, where he had been a national hero. In the past week, several new claims have emerged that Hwang may have used eggs that were paid for, as well as eggs from

4、junior members of his laboratory. Hwangs team, based at South National University, has produced a string of landmark papers in stem cell research, including the first stem cells obtained from a cloned human embryo(胚胎 )(W. S. Hwang et al. Science 303, 1669-1674; 2004) and the first patient-matched em

5、bryonic stem cells(W. S. Hwang et al. Science 308, 1777-1783; 2005). For South Korean scientist, cloning pioneer and Snuppy creator, Woo Suk Hwang, things keep going from bad to worse. Last month, he had to admit that as part of the groundbreaking stem cell research he published in 2004, one of his

6、colleagues had paid some women for their egg donations, and that two of the unpaid donors were Hwangs own junior researchers. Amid the moral controversy that followed, Hwang was in hospital for extreme fatigue and exhaustion. He was released earlier this week, only to find one of his former research

7、ers on a national news broadcast claiming that the history-making stem cell lines Hwang created were fake. The news broadcast was part of a multi-part investigative series by Koreas MBC-TV. Also in the broadcast, the researcher said that Hwang had told him to make up data in order to make it appear

8、as if the South Koreans had created more stem cells, made from patients with diseases, than they actually had. “This is something I shouldnt have done,“ said the researcher, whose face was not shown on camera and was only identified by his last name, Kim. “I had no choice but to do it.“ In a separat

9、e interview, Roh Sung Li, the doctor who had provided donated eggs to Hwangs research, said that Hwang had asked Science, the journal that published his paper on patient-specific stem cells, to withdraw the publication. A spokesperson at the journal said that they had not yet received a request to t

10、ake back, but have e-mailed all 25 co-authors asking for clarification of the allegations(指控 ). Roh told news media that of the 11 stem cell lines created from patients with diseases, nine were fake. Whether the two remaining lines were valid, and photographed repeatedly to stand in for the other li

11、nes, is not clear. Roh also claims that after a visit to Hwang on Thursday, he believes there were no stem cells at all, and that all of the colonies had died in the lab. “I heard some things that I havent been aware of when I visited Professor Hwang at his request, that there are no embryonic stem

12、cells,“ he told MBC. These latest claim comes just 24 hours after a former Hwang cooperator, Dr. Gerald Schatten of the University of Pittsburgh, charged Hwang with fabricating his data. Back in June, the two men had co-authored a paper published in Science that detailed how individual stem cell lin

13、es were created for 11 patients through cloning. When Hwangs immoral deeds were uncovered last month, Schatten was already publicly distancing himself from his onetime colleague. But on Tuesday, Schatten, took the next step and asked that his name be removed from the work. His reasons? “Careful re-e

14、valuations of published figures and tables,“ he said in his letter, “along with new problematic information, now cast substantial doubts about the papers accuracy.“ Hwang has still not responded to these new accusations(指控 ), and Schatten has declined to comment further. Hwangs academic affair is th

15、e latest plot twist in a drama thats playing out in the Korean press. Several days after Schattens initial break with Hwang, Seouls news outlets cited a Korean government official and other sources in both Korea and the U.S., claiming that Schatten had met with Hwang in October and asked for 50% of

16、the patent(专利权 ) on the patient-specific stem cell cloning technique. Schatten also reportedly asked to be named chairman of the board of the newly created World Stem Cell Hub, a research center funded jointly by the South Korean government and private interests. The South Koreans reportedly denied

17、his requests. Despite all the negative publicity, Hwangs popularity didnt seem to be suffering too much. At home, he is enjoying emotional swells of support from thousands of women who have lined up outside his lab doors pledging their willingness to donate eggs to his research. Still, Hwang has a l

18、ot of explaining to do. He is already being investigated by his own university. And earlier this week, eight stem cell scientists, led by Dolly cloner lan Wilmut, submitted a letter to Science, noting that “accusations made in the press about the validity(合法性 ) of the experiments published in South

19、Korea are, in our opinion, best resolved within the scientific community.we encourage Hwangs laboratory to cooperate with us to perform an independent test of his cell lines.“ At stake, say the scientists, is the new field of stem cell science, which holds the potential of introducing new ways to tr

20、eat disease. Until the testing completed, it seems the rumors and the accusations will only continue to deepen. Hopefully, once Hwang is back in the lab, the questions around in the press about his work will be answered. Unfortunately, that may take a while. Hwang is back in the hospital, this time

21、in the mental ward. The effects of the claims on the stem cell field and on Hwangs research are unclear. On 15 November, after the news of Schattens separation, the Korean government laid out plans to invest 11.5 billion won in the World Stem Cell Hub led by Hwang. But it also proposed to separate t

22、he center from Seoul National University and make it an independent body. Many potential overseas cooperators have said their plans are on hold until the claims are resolved. How these events will affect Hwangs teams ability to publish is another open topic. “Its pretty clear that the editor of any

23、journal would be on heightened alert if they received a piece of work from them, and would probably examine it very carefully for the ethics of the work at the very least,“ says Gregory Curfman, executive editor of The New England Journal of Medicine. 2 The passage depicts the difficulty of stem cel
