ANN ARBOR (AP) -- The director of a University of Michigan research center will go before a U.S. Senate panel to testify on the potential of human embryonic stem cells.
AnnArbor.com reported Saturday that Sean Morrison of the university's Center for Stem Cell Biology is among a small group of scientists called to testify before the Senate panel in charge of funding stem cell research.
A federal judge's ruling last month stopped the flow of government research dollars. But late last week, an appeals court temporarily lifted the judge's ban until it can hear full arguments over the funding.
The earlier ruling put millions of dollars of University of Michigan projects at risk. Morrison says it was "like a nuclear bomb for the field" that will cripple research if allowed to stand.
