Derivation of stem cells from human embryos: the principled arguments of potential donors and recipients

Evidence is emerging that embryonic stem cells may have the potential to alleviate many debilitating conditions, but opinions remain polarized on the derivation of stem cells from human embryos obtained during in vitro fertilization treatment. The views of scientists, donors and unaffected members of the general public have been sought, but not those of patients likely to benefit. Semi-structured interviews were completed with 15 people living with Parkinson's disease, 15 with type I diabetes, 15 couples living with infertility and 21 members of the general public. In all four groups, religious, cultural and personal beliefs affected perceptions of the moral status of the embryo and the system of regulating science and scientists involved, overriding differences resulting from their status as potential beneficiaries or facilitators. Whether they came to the interview to defend or promote stem cell research, they cited the same four justifications (utilitarian, ecologic, moral duty and eugenic) but varied in their capacity to present a consistent argument.
