Bob, I did a medline search on the subject Parkinson disease and review articles, in English, 1989 to current. Among these articles were several mentioning that fetal transplants were, as I recall, disappointing. Try crossing subject Parkinson disease and subject fetal tissue transplantation. That may give you a better result. I will try it also. Don't forget Bioethics line, that will give you more ethics and less "hard core" science. Please excuse me if you already know this.
