i'm afraid that appalling description which appeared in Canadian papers was written by a journalist who didnt quite understand a damned thing about what he or she were talking about.
a better description was:
The new approach that will be jointly investigated involves using stem cells generated from an adult’s own tissues, rather than from fetal cells. The adult cells are extracted from the patient’s blood or skin and converted first into stem cells and subsequently into specific dopamine neurons, which are the cells transplanted into the brain.
if the cells are to replace those lost from the substantia nigra the have to grow very long axions to the basal ganglia area where they release the dopamine.
lets hope the canadian scientists are better than their journalists.
