How do you become a volunteer for stem cell research?

A friend of mine has Parkinsons' disease and wants to become one, but he wanted me to find out where on earth he would have to go, what he would have to do, etc? We're contained by Pennsylvania, but he's also okay with leaving the state for it. If he went to the VA or someplace could they impart him all of the information he needs?
