Hwang Woo-suk

However, soon after the first paper was released, an article in the journal Nature accused Hwang of having committed ethical violations by using eggs from his graduate students and from the black market.

[6] The Korea Times reported on June 10, 2007, that Seoul National University fired him, and the South Korean government canceled his financial support and barred him from engaging in stem cell research.

[13] In February 2011, Hwang visited Libya as part of a US$133 million project in the North African country to build a stem cell research center and transfer relevant technology.

His alleged success was touted as the fifth instance in the world in cow cloning, with a notable caveat: Hwang failed to provide scientifically verifiable data for the research, giving only media sessions and photo ops.

Following an intense media probe, Roh Sung-il, one of Hwang's close collaborators and head of MizMedi Women's Hospital, held a news conference on November 21.

Roh claimed Hwang was unaware of this, while the South Korean Ministry of Health asserted that no laws or ethical guidelines had been breached as there were no commercial interests involved.

On November 22, PD Su-cheop (Producer's Note), a popular MBC investigative reporting show, raised the possibility of unethical conduct in the egg cell-acquiring process.

He added that he had lied about the source of the eggs donated to protect the privacy of his female researchers, and that he was not aware of the Declaration of Helsinki, which clearly enumerates his actions as a breach of ethical conduct.

After the press conference, which was aired on all major South Korean television networks, many of the nation's media outlets, government ministries, and members of the public expressed sympathy for Hwang.

Hwang's integrity as a researcher was again put in doubt when it was revealed that PD Su-cheop had scheduled a follow-up report questioning his achievement published in Science in June 2005, which stated he had cloned 11 lines of embryonic stem cells.

Then collaborator Gerald Schatten asked Science to remove his name from the paper, stating as a reason that there were "allegations from someone involved with the experiments that certain elements of the report may be fabricated."

"Roh Sung-il, chairman of the board at Mizmedi Hospital, told KBS television that Hwang had agreed to ask the journal Science to withdraw the paper, published in June to international acclaim.

[...] University of Pittsburgh researcher Gerald Schatten has already asked that Science remove him as the senior author of the report, citing questions about the paper's accuracy.

"[43] On July 26, 2006, Hwang said in testimony that he spent part of 500 million won in private donations in attempts to clone extinct Russian mammoths and Korean tigers.

The panel stated that Hwang's 2004 Science paper was also fabricated and decided the stem cell discussed in the paper may have been generated by a case of parthenogenetic process (which is itself a significant development, as mammals rarely reproduce by parthenogenesis; in addition, this would make Hwang's lab the first ever to successfully generate human stem cells via parthenogenesis, predating other research facilities' successes).

The panel, in conclusion, stated that Hwang's team intentionally fabricated the data in both the 2004 and the 2005 papers, as described by Myung Hee Chung (Head of Seoul National University's investigation) and that it was an act of "deception of the scientific community and the public at large".

Hwang also withdrew 140 million won in August 2001 to buy gifts for his sponsors, including politicians and other prominent social figures, before Chusok holidays, according to prosecutors.

The prosecution added Hwang wired about 200 million won to a Korean American, identified only as Kang, in September 2005 and received the equivalent amount in U.S. currency from him when the scientist visited the United States two months later.

Although Hwang deceived the world about being the first to create artificially cloned human embryos, he did contribute a major breakthrough to the field of stem cell research.

Hwang especially tried to win favor from the Roh Moo-hyun government, which in turn was suffering from a lack of popular support and wanted to demonstrate its competency by creating and promoting an exemplary policy success.

In another instance at the opening of World Stem Cell Hub on October 19, 2005, Roh remarked, "politicians have a responsibility to manage bioethical controversies, not to get in the way of this outstanding research and progress.

"[57] On December 5, 2005, after PD Su-cheop stirred a national controversy, Cheong Wa Dae reaffirmed its unflinching support for Hwang and his research team.

While implying the controversies over MBC-TV's forceful methods used to gather information from Hwang's former junior staff members, Roh said, "The disputes will be resolved gradually and naturally through following scientific research and study.

We will join forces to help Hwang devote himself to his studies", Rep. Kwon Sun-taik of the ruling Uri Party said in a news conference at the National Assembly, who was also the leader of the group.

[60] The MBC investigative journalism show PD Note (Korean: PD수첩) returned on air on January 3, 2006, and summarized the course of Hwang's scandal to date.

"Dr. Hwang will not be able to return to the lab, at least, until at the end of this week because he is extremely exhausted, mentally and physically", a key team member, Ahn Cu Rie, wrote in an e-mail to Reuters.

That conclusion was reached after one of Hwang's close research partners, Ahn Cu-rie, returned Tuesday after a 10-day trip to meet with scientists in the United States and Japan, Seong said.

Don't trample on our one shred of hope", a woman whose son suffers from a severe kidney ailment told South Korean broadcaster YTN at the university.

[62] The site also carried a photo of Hwang and his cloned dog, Snuppy, trimmed with images of the rose of Sharon, South Korea's national flower, in an apparent appeal for patriotism.

Those who applied to donate ova included people with incurable illnesses and their family members, who hoped that Hwang's research would eventually lead to cures, and young, healthy women.

Somatic cell nuclear transfer can create clones for both reproductive and therapeutic purposes. The diagram depicts the removal of the donor nucleus for schematic purposes; in practice the whole donor cell is transferred.
