An overview of the concept of cloning humans
While the creation of embryos for research purposes alone always raises serious ethical questions, the use of somatic cell nuclear transfer to create embryos raises no new issues in this respect.
Many researchers think it is worthwhile to explore the use of embryonic stem cells as a path for treating human diseases. Finding 5: If any attempts at human reproductive cloning were ever to occur, they would constitute research, not merely innovative therapy.
Nevertheless, no voluntary system that is established to restrict reproductive cloning is likely to be completely effective. At present, the use of this technique to create a child would be a premature experiment that would expose the fetus and the developing child to unacceptable risks.

There currently is no solid scientific evidence that anyone has cloned human embryos. While many of these views are religious in origin, the questions raised by cloning are faced by secular perspectives as well.
Human cloning ethics
Finding 8: There is concern that legislation or regulation that would ban reproductive human cloning would set a troubling precedent with respect to the restriction of innovative, experimental research and medical procedures. The procedure consists of inserting a gene from one organism, often referred to as "foreign DNA," into the genetic material of a carrier called a vector. Life scientists conducting research today often clone cells to obtain replicas of the bacterial, animal, or plant cells necessary to perform repeated experiments. In , scientists in South Korea claimed to have successfully cloned a human embryo, but said the experiment was interrupted very early when the clone was just a group of four cells. In macaque monkey embryos were cloned by SCNT, but those clones lived only to the blastocyst stage of embryonic development. Thus, under current law, the use of somatic cell nuclear transfer to create an embryo solely for research purposes is already restricted in cases involving federal funds. This procedure was performed in by American scientists Robert W.
