Human Fertilisation and Embryology Bill [Lords]

We should all subscribe to that principle. It has been stated that research is needed, because it would help adult stem-cell research. However, Dr. James Sherley of the Boston biomedical research institute, who has visited the House and discussed the matter with hon. Members, has described that argument as ““a contrivance””. He has said that placing embryonic stem cells into adult tissue puts them in the wrong place, which is common sense. The very potency of embryonic stem cells means that they can cause tumours, and Dr. Sherley believes that such research is a blind alley.
