...Despite the retraction, Hwang insists he will provide proof of his work in 10 days. Hwang maintains that he did create the groundbreaking stem cell lines from patients, and that he even provided them at the time to six researchers who can vouch for their authenticity. "What I can say for sure is that we did create patient-specific stem cells and we have source technologies to repeat them from scratch," he said, referring to the stem cells he cultured for the first time from 11 patients with diseases...
...Instead, Hwang acknowledged that the images published in Science were problematic, but provided his own explanation: that the stem cells were somehow mismanaged or possibly switched. In January, his team at Seoul National University had created six patient-specific stem cell lines, but they became contaminated. They reported the breach to the government and rescued two batches which they stored temporarily at their partner lab in Mizmedi Hospital. After Hwang's lab was cleaned and new sterilization procedures put into place, the stem cell lines came back to Hwang's lab. His team then went on to create six more...
...separate interview, Roh Sung-Il, the doctor who had provided donated eggs to Hwang?s 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 retraction request, but have e-mailed all 25 co-authors asking for clarification of the fabrication allegations. 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...
...Korean press. Several days after Schatten?s initial break with Hwang, Seoul?s 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 the patent 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 his requests...
...major question raised by such a comparatively high-stakes trial is, Why use such high-risk patients? The last thing people who are already in precarious cardiovascular health need-or so it would seem-is to begin taking a drug that could endanger them even further. Pfizer - not to mention the patients themselves-is apparently banking on the belief that Celebrex simply isn?t that risky, and that any slight dangers are outweighed by the benefits. ?Pfizer is fulfilling the commitment it made over a year ago to study Celebrex in this patient population," says Pfizer spokesman Bryant Haskins.
