Korea's accelerating stem-cell work prompts calls for global ethical rules

摘要

A landmark paper in stem-cell research has been seized on by both sides of the cloning debate, as they seek to further their respective causes. But the advance has also led ethicists to call for broader international agreement over how such studies should be conducted. On 19 May, a team led by Woo Suk Hwar of Seoul National University in South Kore reported that it had created 11 human embryonic stem-cell lines that are genetically matched to individual patients (W.
