A decision by the U.K. High Court last week effectively derailed the British government's plans for allowing and regulating stem cell research. But the victory for anti-therapeutic cloning forces is likely to be no more than temporary.

The case was brought by the anti-abortion Pro-Life Alliance after Parliament in January passed new rules allowing researchers to derive and use human embryonic stem cells and conduct nuclear transfer experiments with human cells. The work was to be regulated under the 1990 Human Fertilisation & Embryology Act, which already regulates fertility treatments (see BioCentury, Feb. 5).
