Phil & others, Have you seen some of the studies of late, re - Stem cells from bone marrow? This source, like fetal sources are still off in the future. BUT, with "primitive neuro cells" harvested and made from our own bodies, there is much less chance of rejection. I personally feel that this process is the much "safer" route. It also bypasses the moral dilemma revolving around fetal sources. I have a dear friend that has had a heart transplant (10 years ago). Rejection is the biggest risk he has, even after all these years. The drugs he has to take to suppress his immune system put him at constant risk. Perhaps using your OWN bone marrow could finally bring about a "true healing" of PD; not just a trading of one for another set of medical problems. Even worse would be facing cell rejection AND worsening PD!!! Politics aside, lets become vocal about funding, and support for studies relating to harvesting cells from bone marrow. The fetal issue is fraught with emotional & moral dilemma's that could waste VALUBLE time and money. No mater how badly one section of society may press for fetal cell sources, the other side would wage just as hard to see that it NEVER happens. 20 years from now we may still be muddled in this moral debate. Let's put our money on the horse that NO politician would oppose: 1st rate, large studies using bone marrow! THIS IS a battle we can win! Take care David Meigs aka: Pappy [log in to unmask]
