"The beef is that there is no question that embryos are destroyed in the harvesting of stem cells," Maxwell said. "Now you are destroying a human being."
Many scientists disagree. Crouse, who specializes in embryonic stem cells, said it boils down to a difference in perspective about when human life begins.
He said, "There is no baby, no abortion."
In fact, Crouse said, the embryos that are used are essentially medical waste.
Most embryonic stem cells used in U.S. research come from embryos left over from in vitro fertilization - where a woman's eggs are fertilized outside the womb and the resulting embryos are implanted in the uterus. If the embryos are not implanted, they are typically destroyed.
