OMAHA, Neb. (AP) - The University of Nebraska's governing board is expecting a contentious vote on whether to keep rules limiting stem-cell research.

The Board of Regents will likely vote Friday on a resolution that would limit such research at the university system's facilities to existing stem-cell lines. The rules were approved under President George W. Bush.

President Barack Obama removed government funding restrictions on new stem-cell lines.

State law prohibits the use of state resources for creating or destroying embryos for research. It was a compromise between university researchers and abortion opponents, who agreed not to pursue further legislation if certain conditions were met.

They say that doesn't apply to lobbying regents.
