In 2004, FRONTLINE correspondent Dave Iverson received the same news that had been delivered to his father and older brother years earlier: He had Parkinson's disease, a degenerative neurological disorder that affects more than 1 million Americans, the causes of which remain largely unknown and the cure for which has proved frustratingly elusive. In My Father, My Brother, and Me, airing Feb. 3, 2009, at 9 P.M. ET on PBS (check local listings), Iverson sets off on a personal journey to understand the disease that has taken such a toll on his family.

In one segment of the program, HSCI Principal Faculty member Ole Isacson brings Iverson into the lab for an up close look at embryonic stem cells.
