This situation is unacceptable to the segment of the electorate that is pro-life and anti-abortion-a segment that includes the president of the United States. Research has been stymied by a four-year-old federal policy that limits federal funding to a narrow group of existing stem-cell lines.

Despite opposition from the pro-life bloc, there are signs that efforts to fund more research in this field are gaining momentum:
