Michigan politics threaten to disrupt embryonic stem cell research at the state university level. The Detroit Free Press reports that some on a Republican-led state House panel are threatening to cut some of the University of Michigan's state funding, unless it reveals the number of embryonic stem cell lines it uses for research. So far, university officials have declined to give precise numbers, and have said most of their research involves adult stem cells anyway. University of Michigan president Mary Sue Coleman is quoted as saying that the university doesn't have exact stem cell numbers. She urged focus instead on stem cell-related medical advances fueled by the research. Michigan lawmakers approved language in last year's budget requiring universities to report a number of details about human embryonic research, according to the piece. Story
