Discuss the ethical concerns and political issues of the use of embryonic stem cells (ESC)

What will be an ideal response?


Despite the potential, ESC research is fraught with controversy because of the source of these cells: they are isolated from discarded embryos from abortion clinics and in vitro fertility ("test-tube baby") clinics. Opponents of using ESC are morally and ethically concerned because embryos are destroyed in the process of harvesting these cells. Proponents argue that these embryos were destined to be destroyed anyway (a decision already made by the parents of the embryos) and that these stem cells have great potential for alleviating human suffering. As such, ESC science has become inextricably linked with stem cell politics.
