Once a rising star in television and movies, Michael J. Fox has a new mission to promote stem cell research.
Fox toured the University of Wisconsin's Waisman Center Tuesday with Governor Doyle. He is promoting stem cell research which he says can save lives.
His visit happens on the heels of Dr. Su-Chun Zhang's announcement of a stem cell breakthrough.
A Parkinson's patient himself, Fox is a strong advocate for Parkinson's and stem cell research. His foundation has raised more than $50 million dollars.
