Kerry accuses Bush of blocking stem cell research

DEMOCRATIC challenger John Kerry yesterday broadened his attack on President George W Bush to include stem cell research when he accused his rival of ignoring science that could offer millions of sick Americans a chance at a cure.

Campaigning in New Hampshire alongside actor and activist Michael J Fox, who has Parkinson's disease, the Massachusetts senator said if elected he would remove Mr Bush's restrictions on using federal money for stem cell research and boost funding.

Stem cells are unprogrammed master cells that can give rise to various cells and tissues. Scientists believe that while the cells could lead to cures for ailments like Parkinson's and spinal cord injuries, such advances would be years and perhaps decades away.
