황우석의 매머드 언론플레이를 듣고 Alan Boyle이 쓴 글

일본의 Akira Iritani옹이 몇달 전에 매머드 복제한다고 언론플레이를 한 뒤에 Alan Boyle이 Miller의 견해를 물어 쓴 글을 소개해 드린 바 있습니다.

이번에 황우석의 매머드 언론플레이 소식을 듣고 이에 대해 글을 썼네요.

했던 소리 길게 다시 할 필요가 없다고 생각했는지 자기가 썼던 옛 기사를 링크하고 끝에 간단하게만 코멘트했습니다.

That's a big "if," as I wrote in December when I discussed the Japanese-Russian project. In addition to the usual problems surrounding interspecies cloning, it's highly doubtful that genetic material recovered from tissue that's been frozen for millennia would be sufficiently intact for extraction and implantation.

이종간 복제라는 문제 외에도 동토에서 채취된 샘플에서 복제에 사용될만큼 온전한 세포를 구할 수 있겠느냐? 회의적이라는 이야기입니다.

그래 놓고 설문조사를 올렸네요.

Years after scandal, scientist leads campaign to resurrect mammoth

By Alan Boyle

Russian and South Korean scientists, including the cloning expert who was the focus of a stem-cell scandal six years ago, have signed a deal to try re-creating a woolly mammoth using cells recovered from 10,000-year-old frozen remains.

The papers for the joint research project were signed on Tuesday by Hwang Woo-Suk, chief technology officer for South Korea's Sooam Biotech Research Foundation; and Vasily Vasiliev, vice director of Russia's North-Eastern Federal University, during a ceremony at Hwang's office in Seoul.

Hwang is infamous for his role in human embryonic stem-cell research: In 2004 and 2005, he and his colleagues claimed to have extracted stem cells from what they characterized as the world's first cloned human embryos. But in late 2005, his work was found to have been based on fabricated data, and he was barred from continuing research with human cells.

Despite the disgrace, Hwang continued working with animal cloning techniques. Before the scandal broke, his team announced that they produced the world's first cloned dog, nicknamed Snuppy, and that claim has stood up to scrutiny. Last October, Hwang's team at Sooam unveiled eight cloned coyotes that had been produced by injecting nuclei from coyote skin cells into dog eggs. At the time, he said he was interested in cloning an endangered African dog species known as the lycaon ... and was interested in cloning a mammoth, too.

In December, Japanese news media said that scientists recovered a seemingly viable sample of bone marrow from a frozen mammoth thigh bone in Russia's Sakha Republic, and that a mammoth could be cloned back from extinction within five years. This week, Agence France-Presse reported that North-Eastern Federal University is working with the Japanese scientists and with the Koreans. The Beijing Genomics Institute is said to be taking part in the Korean-Russian project as well.

Reports from Seoul suggest that the mammoth-cloning effort could be launched this year if the Russians can ship the remains to Sooam's laboratory. "The first and hardest mission is to restore mammoth cells," a colleague of Hwang's at Sooam, Hwang In-Sung, told AFP.

This diagram released by the Sooam Biotech Research Foundation shows the process of replacing the nuclei of elephant egg cells with those taken from the mammoth's somatic cells to bring a mammoth back to life.

The plan calls for extracting nuclei from the thawed-out mammoth cells, putting them into elephant egg cells and stimulating the cells to start dividing. Embryos would be implanted into elephant wombs for gestation — and if the effort is successful, a mother elephant would give birth to a baby mammoth around 22 months later.

That's a big "if," as I wrote in December when I discussed the Japanese-Russian project. In addition to the usual problems surrounding interspecies cloning, it's highly doubtful that genetic material recovered from tissue that's been frozen for millennia would be sufficiently intact for extraction and implantation.

셀을 복원하는 것에 의문을 제기했군요...........신태영교수는 합성셀을 만들어서 해결한다 한 것 같은데........그기 가능한 것인지..공상과학소설 써제끼고......아님 말고.,,,,,,,,이럼 곤란~

[죽순]

합성쎌이라는 뜬구름 잡는 소리 말고

가루가 되어 버린 DNA 조각을 딱풀로 붙여서 사용한다는 것 외에 또 한가지 방법이 제시된 것이 있어요.

매머드 게놈을 설계도로 생각하여 코끼리부터 시작하여 유전자 조작으로 매머드를 만든다는 것이지요.

이게 그래도 가장 현실성이 있는 방법인데, 전문가들 중에도 비관적으로 보는 사람이 있고 낙관적으로 보는 사람이 있어요.

[죽순]

Miller 같은 사람은 비관적으로 보아 누군가 그런 일을 한다면 내 손에 장을 지지겠다고 합니다.

Poiner 같은 사람은 50년쯤 후에는 가능하지 않을까 조심스럽게 낙관합니다.

[죽순]

한마디로 사람 게놈을 설계도로 생각하고 침팬지로부터 시작하여 유전자 조작을 하여 사람을 만드는 것과 비슷한 일입니다.

황당해 보이지만 그래도 이게 가장 현실성 있는 방법이라는 것.
