Dolly: a decade on

[摘要] The birth of Dolly the sheep in 1997 sparked a media frenzy and a prolonged ethical debate. Ten years later, the ethical debate launched by Dolly has changed. It has been supplanted by one that is more complex, more rooted in reality and far more relevant to the research that scientists want to do. What occur move the ethical debate in an unforeseen direction, was the isolation of human embryonic stem-cell lines by James Thomson and his colleagues at the University of Wisconsin, Madison. With that achievement, it became clear that broad research avenues could be opened up by cloning human embryos to extract stem cells. But as quickly as scientists recognized the potential of such opportunities, political and ethical opponents argued that research cloning was a fundamental assault on human dignity.
