Stem cells provide great promise in the development of new treatments for diseases, such as, diabetes and spinal cord injury. Stem cell research has raised many ethical issues on human life, and human reproduction. The ethical debates originate from scientists extracting stem cells from blastocyst. Production of induced pluripotent stem cells raises fewer questions, compared to use of embryotic stem cells. Other ethical issues though still remain, for example, consent in the donation of material and methods involved in early clinical trials. Adult stem cells do not raise ethical issues, and are used in stem cell research and clinical care.
Individuals against stem cell research claim an embryo should be accorded the same rights as any human being. From a religious perspective, life being at the moment of conception, and therefore use of embryos in stem cell research is morally wrong. Protagonists of stem cell research though claim that the embryo only develops into a human being further done the line, and therefore should not be accorded the same moral status as a human being. They claim the embryo is simply a cluster of cells, which can be used in stem cell research without need for restrictions.
