Last week, the National Institutes of Health issued long-awaited guidelines that will allow scientists receiving federal funds to study stem cells taken from frozen embryos. The embryos used will only be those that are formed as a result of in-vitro fertilization, and are then abandoned at private clinics. Their use has been a deeply-contested issue. Host Jacki Lyden discusses the ethical concerns over this type of research with Dr. Arthur Caplan, Director of the Center for Bioethics at the University of Pennyslvannia.
