THE government must double its current investment in stem cell research or risk being left behind by America, a prominent Scottish academic has warned.

Lord Naren Patel of Dunkeld, the chancellor of Dundee University, said the UK is between £20m and £30m short of the level of funding it needs to sustain itself as the world leader in stem cell research.

Lord Patel was speaking at the launch of a network to co-ordinate and promote the UK's stem cell science effort.

The UK National Stem Cell Network (UKNSCN) aims to enhance basic research at a network of universities throughout Scotland and the UK, and help speed its translation into clinical applications.

Lord Patel, a world renowned obstetrician, is the first chairman of the UKNSCN steering committee.

At the launch yesterday, he said the government was failing to meet the funding targets outlined to them in the Pattison report in 2005, while both the US and Japan have been increasing their budgets.
