Innovative treatment or ethical headache? Fetal transplantation in Parkinson's disease

Current drug therapies have limitations in controlling Parkinson's disease in the long term. Early results of fetal cell transplantation are encouraging, suggesting it may help many sufferers. The technique raises ethical considerations, particularly with regard to collection of fetal tissue. Nurses must form their own opinions on the technique, and while they may opt out of the actual operations involved, they still have a duty of care to these patients.
