But by then an aggressive investigative team from MBC, a Korean TV network, had got wind of the allegations. The reporters interviewed many of the egg donors, some of whom said they had not been told they were part of a study, and confirmed that their eggs had been paid for. MBC was also hot on the trail of something even bigger: a tip that Hwang's 2005 Science paper might contain fraudulent data. To verify the allegations, MBC requested samples of the stem cells, which...
...group of young professors at S.N.U. upped the ante by demanding an investigation--a demand the university's president initially refused. But a week later Hwang, who had been hospitalized on and off for "stress and exhaustion," appeared publicly to announce that he was retracting the suspect Science paper. MBC's request for samples had led him to do a retest, and to his surprise, he said, they were invalid. His theory: someone had switched the samples when they were at MizMedi to be photographed (his lab didn't have the right microphotography equipment) and stored. Later he accused...
...Hwang did not specifically address the most serious charge which aired on the Korean network MBC-TV on Thursday night.

...When producers of an investigative television program from MBC-TV raised questions about the validity of the stem cells following the egg-donor scandal, Hwang provided MBC-TV with samples from five stem cell lines, and cells from their donors, in an effort to prove their authenticity. It's not clear where these stem cells were stored. Hwang said he and his colleagues performed their own in-house test, including DNA fingerprinting to verify the source of the stem cells. It was then that he discovered that the fingerprints did not match those printed in Science. "We learned that...
...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 haven?t been aware of when I visited Professor Hwang at his request, that there are no embryonic stem cells,? he told MBC...
