Michael J. Fox's Personal Battle

Michael says America has a lot of ground to make up when it comes to stem cell research. "We had eight years where there was no forward progress and some things people don't even understand," he says.

"For example, if you say no federal funding for stem cell research, that means if there's a university or hospital that receives any funding for anything, they can't do even privately funded stem cell research," he says. "The kind of iterations of impact were really severe."

Watch as Dr. Oz explains the medical benefits of stem cells.

Thanks to recent scientific discoveries, Dr. Oz says stem cells aren't the only solution. "We went to a place we never thought we would go," he says. "I can take a little bit of your skin, take those cells and get them to go back in time so they're like they were when you were first made."

Dr. Oz says these skin cells, which contain your genes and are less prone to cancer, will be the ones that are ultimately used to cure Parkinson's. "I think we're single digit years away from making a big impact in the lives of [people with] Parkinson's disease, but also diabetics and heart attack victims," he says.
