Abstract

Stem cell research is undeniably valuable and has generated excitement in the scientific community because of its potential use in developing new therapeutic treatments for chronic and debilitating diseases. Many researchers believe that the development of new human embryonic stem cell (hESC) lines is necessary for success in this research forum. A review of hESC research based on the four principles of biomedical ethics—autonomy, beneficence, nonmaleficence, and justice—reveals areas of ethical conflict. Specifically, the ethical principles of beneficence and nonmaleficence conflict with the destruction of human embryos in hESC research. Two other ethical approaches that may also be used to evaluate hESC research are the utilitarian and Kantian perspectives. Human embryonic stem cell research demonstrates a divergence from morality because persons (embryos) are treated as means rather than as ends in themselves. Using adult stem cells for research is a viable option that does not pose ethical concerns and yet answers the duty of beneficence that a moral obligation to humanity demands.
