SCNT involves transferring the nucleus of a somatic cell into an oocyte from which the nucleus and thus most of the DNA has been removed.(The mitochondrial DNA in the cytoplasm is still present).
However, since reproductive cloning of mammals has become routine in several countries, there is reason to believe that at some point in the future, humans will be cloned too.
Moreover, even if cloning will not be possible in the near future, cloning for research and therapeutic purposes is likely to be.
Smith, “Human Cloning Obfuscation 6: German Style” (blog post), National Review Online, May 20, 2013, For example, a search for the phrase “human cloning” in the Lexis Nexis database of English-language newspapers gives 85 results for the week following the announcement of Mitalipov’s cloning paper (May 15 to May 22, 2013) and only another 150 for the rest of 2013 (May 23 to December 31, 2013).

For the remainder of that year (April 1 to December 31, 1997), there are another 501 results.
Calendar year 1998 gives another 1,080 results, and calendar year 1999 gives 623.The researchers’ paper, published online in the science journal Cell, And yet no such debate has materialized. Congress held a series of hearings on the ethics of cloning, a federal bioethics commission was charged with making “every effort to consult with ethicists, theologians, scientists, physicians, and other citizens” to address the ethical and legal implications of the Dolly breakthrough, The United Nations General Assembly in 2005 adopted a declaration calling on its member nations to “prohibit all forms of human cloning inasmuch as they are incompatible with human dignity and the protection of human life.” Today, these passionate and proactive debates regarding both the extraordinary hopes for and the deep moral anxieties about human cloning have all but disappeared from the public discourse — a failing this report is intended to help rectify.While news of the Oregon cloning breakthrough was widely reported, very few publications offered editorials or op-eds discussing its implications; radio, television, and Internet outlets produced nearly no in-depth analyses or panel discussions; and policymakers stayed almost entirely silent. As human cloning has arrived on our doorstep, we need now more than ever to discuss the ethical problems it raises and to develop a plausible political and legal approach to address those problems.n May 2013, American scientists announced a long-awaited development: that they had produced stem cells from cloned human embryos.Using a technique called nuclear transfer — the same technique employed by Scottish researchers over a decade earlier to create the cloned sheep Dolly — Shoukhrat Mitalipov and his team at Oregon Health & Science University removed the nuclei from human egg cells and inserted nuclei taken from skin cells; the resulting cloned embryos were then destroyed to produce stem cells.The manipulated oocyte is then treated with an electric current in order to stimulate cell division, resulting in the formation of an embryo.The embryo is (virtually) genetically identical to, and thus a clone of the somatic cell donor.She represented a first undesirable and dangerous step to applying reproductive cloning in humans, something that many agreed should never be done.Only a small minority thought it was permissible, or even morally obligatory to conduct further research into human reproductive cloning.Clinton, “Remarks Announcing the Prohibition on Federal Funding for Cloning of Human Beings and an Exchange With Reporters,” Public Papers of the Presidents of the United States: William J.Clinton (1997, Book I), March 4, 1997, Washington, D.
