Four members of the University of Nebraska Board of Regents have drafted a resolution that would limit embryonic stem-cell research at the university system's facilities.

The resolution would restrict stem-cell research to only stem-cell lines approved under former President George W. Bush.

The resolution's co-authors are Tim Clare of Lincoln, Bob Phares of North Platte and Randy Ferlic and Howard Hawks of Omaha. The move follows President Barack Obama's lifting of government funding restrictions for research on new lines of stem cells.

A 2008 Nebraska law prohibits the use of state money or facilities for creating or destroying embryos for stem-cell research using a technique commonly referred to as therapeutic cloning.
