The mixing up of stem cells, cloning and illicit use embryonic cells has disrupted meaningful conversation, and in some countries legislation, around the use of stem cells. There may be some overlap in technique between stem cell research and human cloning, but doctors and researchers are now advising some governments and the United Nations to begin considering these as separate issues as they can be legislated and regulated separately, as is currently the case many countries, such as Belgium. Likewise due to developments stem cells taken from donated amniotic fluid are now thought to how as much promise as embryonic stem cells, but without the moral concerns. With the ethical grey area removed stem cell treatments represent a net-positive, giving hope of treatment to diseases we currently have no way of treating, such as Alzheimers, Parkinson's, and spinal chord injuries, as well as some of societies biggest killers, like cancer and heart disease. Policy and research can ensure this is less of an ethical issue, so research should be allowed to go ahead.
