Ethics, politics, and human embryo stem cell research

Three reports on ethical aspects of research involving human embryonic stem cells were issued in the final months of 1999. Two were from governmental agencies or commissions: the National institutes of Health and the National Bioethics Advisory Commission. The third report was issued by the American Association for the Advancement of Science and the Institute for Civil Soc iety. All three reports endorse the use of federal funds for embryonic stem cell research, but other differences distinguish these reports. This artic le describes the differences and provides an ethical analysis of the main a rguments.
