The worst case could see stem cells morphing into teratomas, particularly gruesome tumors that can contain hair, teeth and other body parts. This process by which science becomes medicine is often long, but it is designed to minimize patient harm and to maximize the likelihood of effectiveness.
In some cases, the male partners of these women are also excluded or required to take birth control measures. Their potential is evident in the use of blood stem cells to treat diseases of the blood, a therapy that has saved the lives of thousands of children with leukemia; and can be seen in the use of stem cells for tissue grafts to treat diseases or injury to the bone, skin and surface of the eye.
It is a serious sin to deliberately endorse or promote any of these actions, and no candidate who really wants to advance the common good will support any action contrary to the non-negotiable principles involved in these issues.
