Scientists Heartened at Prospect of End to Stem Cell Ban

"This should give more general acceptance to stem cell research, because now, there won't be this stigma associated with it as much," Sanberg said.

And, perhaps, a new federal policy would spur organizations such as the American Heart Association -- which currently does not fund research involving human embryonic stem cells or stem cells derived from fetal tissue -- to channel funds into this line of research, Sanberg added. (The heart association said it "recognizes the value of all types of stem cell research and supports federal funding of this research.")

Still, Sanberg pointed out, some ethical issues surrounding stem cell research and its application will remain.

For instance, he said, "There still needs to be some oversight on the uses of stem cells and cloning."
