What are people who don't support making embryos for research usually in support of?, Context: The UMC supports federal funding for research on embryos created for IVF that remain after the procreative efforts have ceased, if the embryos were provided for research instead of being destroyed, were not obtained by sale, and those donating had given prior informed consent for the research purposes. The UMC stands in "opposition to the creation of embryos for the sake of research" as "a human embryo, even at its earliest stages, commands our reverence." It supports research on stem cells retrieved from umbilical cords and adult stem cells, stating that there are "few moral questions" raised by this issue.
