Stem cell progress

The science world may - or may not - be on the verge of a happy ending.
과학의 세계는 아마도 해피엔딩의 선상에 있거나 그렇지 않을 것이다.

If the research bears out, stem cells, which form new body parts to replace damaged ones, could come from simple skin cells - thus canceling the need to use human embryos.
만약 줄기세포 연구를 계속 해 나간다면 단순한 피부 조직으로 부터 손상된 부분을 대체하는 것으로 신체의 새로운 부분을 구성하게 될 것이다. 그리하여 인간근원에 대한 연구는 별 의미가 없어 질 것이다.

An ethical and religious furor could vanish if the notion of human embryos carved up in petri dishes went away. New breakthroughs, vast medical potential and no politics: that's the pleasing promise that the skin cell development offers.
만약 인간 근원의 믿음이 나눠져서 페트리 접시에 담겨 진다면 도덕주의자나 종교지도자들은


Except it's not likely so simple. For now, the battle to fund and study embryos must continue if science and its political patrons are serious about exploring a medical frontier. Sorry, but this battle isn't over.
The work on skin cells, it turns out, isn't very far along. Two separate teams - one in Japan and the other at the University of Wisconsin - reported the findings. But the cells were injected with viruses to get results, a method that could bring tumors or cancer. Years of work will be needed to minimize the dangers.
In the meantime, embryo research, with all its ethical worries for critics, is further along. President Bush's top science adviser tried to suggest otherwise by noting that the skin cell work showed that persistent science could find an alternative. He's right to salute the skin cell milestone, joining nearly every other researcher looking for political relief in this science war. But he's wrong to suggest that a two-front war - embryos and skin cells - isn't needed.
Congress should take note too. After two White House vetoes of stem cell spending (because of concerns about expanded embryo work), Congress is trying to rouse itself to try again. The skin cell announcement is likely to dampen this effort. After all, why bother fighting a determined president when it looks like skin cells may work just as well?
That kind of thinking is politics, not science. The country needs to move on both fronts if it genuinely wants results in a promising field.
As if stem cell work wasn't challenging enough, California is making harder. The voter-backed Institute for Regenerative Medicine has encountered its own ethical trouble. A board member lobbied the stem cell research body to overturn a rejected research proposal from a colleague.
It was an intolerable violation of ethical guidelines. Stem cell work both here and nationally must adhere to the highest standards.
