Dr. Neil Theise, an adult stem cell researcher and professor of pathology and medicine at the Beth Israel Medical Center of Albert Einstein College of Medicine in New York, said that a lifting of the embryonic stem cell research ban would "lift the need for political opposition to adult stem cell research, as well" and have benefits across the board for all forms of stem cell research.
"It is by pursuing both paths that practical therapeutic and industrial benefits can manifest in the swiftest, most safe and cost-effective manner," he said.
But others believe that opening the gates to federal funds could have the exact opposite effect, actually decreasing the amount of money available to researchers.
"Unless there is a boost in funding for this research at the NIH, it is highly likely that funding for currently allowed research will actually decrease as the pool of funds gets diluted by new applications," Sanberg said. "Overall funding for stem cell research in our country could decrease if the states feel less inclined to fund their own stem cell initiatives in a downward economy, thinking that the federal government is now funding all stem cell research."
Groups opposed to embryonic stem cell research predicted such a slip in overall funding, as well.
"The concern with new federal policies is that any rush to create new lines from embryos will simply siphon valuable funds away from research with much greater potential, including iPS cells, and especially existing and developing adult stem cell therapies that are already treating patients for dozens of diseases," said David Prentice, senior fellow for life sciences for the Family Research Council, a Christian political organization that opposes embryonic stem cell research.
