Stem cell research has great potential

Seven out of ten of those surveyed said the use of human embryos was acceptable in research to find treatments for serious diseases and in fertility research.

However, just one in six felt that it was acceptable to use human embryos in all forms of medical research.

The survey was commissioned by a coalition of organisations with a common interest in stem cell research, including the Parkinson's Disease Society and the Medical Research Council (MRC).

Many scientists believe that the use of stem cells offers great potential for yielding new treatments for degenerative diseases such as Parkinson's, Alzheimer's disease, leukaemia, strokes, heart attacks and spinal cord injuries.

Stem cells are cells at an early stage of development which have the potential to turn into many different types of tissue.

They can be taken from adult tissue samples, or samples taken from human embryos.

It is thought that embryonic stem cells may prove to be much more versatile in being adapted for medical use than adult cells.

But their use has raised ethical objections.

Strict framework

Robert Meadowcroft, of the Parkinson's Disease Society, said: "It is most encouraging that the survey results clearly demonstrate wide public support for this vital area of research.

"This will give hope not only to people with Parkinson's and their carers but to many others with long term degenerative diseases and illnesses."

Sir George Radda, MRC chief executive, said he was encouraged by the results.

He said: "We hope the public will be reassured that the UK is one of the world leaders in ethically developing this area of research within a strict legal framework.

"Stem cell research holds great potential for curing serious and life threatening diseases and we aim to make sure this progresses responsibly for everyone�s benefit.

"The results of this poll show the British public has a good grasp of the importance of ethical medical research and where it would draw a moral and ethical line. We need to keep them engaged in this debate; their voice is important."
