Ethical issues in stem cell research.

Abstract

Like most cutting edge medical technology, human stem cell research raises a number of difficult and important ethical issues and concerns, requiring potential benefits to be balanced against the need to protect the rights and welfare of citizens. Much of the debate involves research using embryonic stem (ES) cells, which in turns revolves around the moral status of the human embryo, and the level of respect and protection that should be accorded. This is an especially sensitive issue in pluralistic societies where different, if not conflicting, cultural and religious perspectives exist. Another contentious issue as far as the derivation of ES cells is concerned is the intent involved in producing the embryos, specifically whether it is ethically permissible to allowing embryos to be made solely for the purpose of research. These and several other relevant ethical issues will be discussed, including a comparison of guidelines and positions adopted in different countries.
