The director of the University of Michigan's Cancer Center is stepping down.
Dr. Max Wicha has served as the center's director for 27 years. He says it's time for him to pass the torch to a new leader, but adds he will remain at the center to continue his stem cell research.
Wicha says he will stay on as the center's director until a replacement can be hired. The university expects to fill the position by mid-2014.
