Professor Ian Wilmut, the scientist who cloned Dolly the sheep, has this week said he hopes to move into cloning human embryo cells. By using this controversial research, known as 'therapeutic cloning', Professor Wilmut hopes to gain insights into motor neurone disease.
The Roslin Institute, at which Professor Wilmut works, will first have to apply to the Human Fertilisation and Embryology Authority (HFEA) for a license. So what does Suzi Leather, Chair of the HFEA, think of his proposals? Is it essential research in the fight against disease or a step too far?
Ms Leather will be speaking on this subject and others at the x-change on Tuesday 27 April. She will be joined by Clive Cookson, Science Editor of the Financial Times and Dr Lionel Milgrom, Alternative practitioner and MD of a university biotech spin-out company.
