Japan is go for clinic trials to transplant iPS cells into human brain to cure PD
 

This is great news but if stem cells are good for the brain, why not put them into the brain intranasally? It seems so much easier!
A nasal spray delivery system for stem cells could help avoid problems related to surgical implantation of stem cells. This new method could also make repeated stem cell treatments much safer.

Such a great idea! It could be cheaper too.

Did you see they do not have government (such as a "FDA") involved? Mostly scientists, professors in Kyoto University's commission. However, the Japanese government did entire funding to the program, billions of dollars. I am not against FDA but, where there is government there is bureaucratic...easily. Now we see we are behind. Should we ever be behind?

Lets prey for its success!
