Hi Nancy and Ed, The NIH and the National Library of Medicine recently started a website listing current clinical trials funded by NIH. It is at: http://clinicaltrials.gov/ct/gui They currently show 17 trials for PD that are recruiting patients. Until the U.S. federal stem cell research regulations are accepted and finalized, I don't think NIH, or any federal agency can fund research involving stem cells. Here is the current list of trials that are recruiting - more info. about each one is available on the web site.
