Michigan Gov. Jennifer Granholm and Detroit Mayor Dave Bing are expected to announce the city will be the host of a convention next October on stem cell research and commercialization.

A person with knowledge of the event says the World Stem Cell Summit will bring its annual three-day event to Detroit. The person isn't authorized to comment and requested anonymity.

Granholm, Bing and representatives of University of Michigan, Michigan State University and Wayne State University plan to announce the summit Thursday afternoon.

A message was left Wednesday afternoon for a Granholm spokeswoman.

The event is expected to draw more than 1,200 business, academic and government leaders from 25 countries. This year's summit was held last month in Baltimore.
