A Senate vote that had been expected to open more stem cell research to federal funding appeared stalled as sponsors of alternative bills discussed which should have priority. The Senate had appeared poised to pass legislation similar to a House-passed measure President George W. Bush has vowed to veto, one that would lift current restrictions on U.S. funding for research using stem cells from embryos. Some senators are looking at work by the Reproductive Genetics Institute, which has developed its own line of stem cells without human embryos that could be used for research.
