Greg,

I agree with you; it does seem they're putting the cart before the horse. I noted that at least Stanford researchers are noting this. Wernig pretty much said older onset people may be good to go with just one implant. It is pretty wild that they are on the brink of completing half of our cure. This only highlights how they really need to rethink the scattershot approach.

It also brings up that since they can create dopamine neurons; they can use them to now induce PD or observe in us somehow to watch how everything unfolds. Basically they will have much more authentic model than what we now have in lab animals. From what I have read, they can mimic l we That is very promising; maybe stem cells will find out how the party got started in the first place...
