摘要

When the history of the 21st century comes to be written, Sunday November 25th is likely to contribute at least a footnote, and possibly the start of a chapter. That was the day when a previously obscure Massachusetts company, Advanced Cell Technology (ACT), announced in an equally obscure online journal that it had cloned the first human embryo.rnWhether this is a scientific milestone remains doubtful (see page 76). The company was not trying to create a human being (reproductive cloning, in the jargon), just an embryo, from which it could derive stem cells (therapeutic cloning). Stem cells, which can transform themselves into any of the body's tissues, promise cures for degenerative diseases, such as Parkinson's. But the company got nowhere near that aim. All the embryos died and it is unclear whether the company prompted the eggs to produce any new cells. No wonder the professor who chairs the ACT'S ethics board cautiously described the cells not as "embryos" at all but merely as "cleaving eggs". Nonetheless, for a few hours, the first making of a human life was stirring in a test tube, put there by genetic manipulation.
