About half the patients being treated at US fertility clinics say they’d be willing to donate their unused embryos for stem cell research, a new survey reports.
In a survey of over a thousand patients who have created and frozen embryos as part of fertility treatment, 60 percent said they would be likely to donate unused embryos for stem cell research, according to a study led by researchers at Duke University Medical Center and Johns Hopkins University.
The researchers published their findings online in the June 21, 2007 Science Express, the online component of the journal Science, and the study will be published in the journal’s July 6, 2007 print issue.
These findings suggest that the number of embryos potentially available for stem cell research may be 10 times higher than previous estimates, resulting in a potential 100-fold increase in the number of stem cell lines — groups of stem cells derived from a single source — available for federally funded research.
However, such a move also became less of a possibility on Wednesday, after President Bush for the second time vetoed a bill that would have loosened federal restrictions on funding for embryonic stem cell research.
