The Obama administration on Monday issued final rules governing stem cell research, addressing complaints from scientists that the rules proposed in April would have outlawed even some of the stem cell lines approved by President Bush. Those rules required lengthy consent forms whose stipulations were too rigid, some scientists argued. The National Institutes of Health will loosen the reins a bit, says acting director Raynard Kington, but will still apply rigorous guidelines in opening up funding for newly established lines. "We anticipate a substantial expansion of stem cell research," Kington says. (Text from The Daily Briefing)
