Cloning Stem Cells From Cloned Embryos Case Study

Decent Essays

A less common view holds that obtaining stem cells from cloned embryos poses fewer ethical problems than obtaining stem cells from discarded IVF embryos. Several Scientist and Ethicist have argued that embryos resulting from SCNT do not have the same moral status we normally accord to other embryos: the combination of a somatic nucleus and an enucleated egg a “transnuclear egg”, is a mere “artifact” with no “natural purpose” or potential “to evolve into an embryo and eventually a human being,” and therefore falls outside the category of human beings. A similar argument views that obtaining stem cells from cloned embryos is less morally problematic because embryos resulting from SCNT are better thought of as tissue culture, whereas IVF …show more content…

If cloning for therapy became available, its application would thus likely be restricted to chronic conditions. Wilmut , who cloned Dolly, has suggested that cloning treatments could be targeted to maximize benefit: an older person with heart disease could be treated with stem cells that are not a genetic match, take drugs to suppress her immune system for the rest of her life, and live with the side-effects; a younger person might benefit from stem cells from cloned embryos that match exactly. Devolder and Savulescu have argued that objections about economic cost are most forceful against ‘cloning for self-transplantation’ than, for example, against cloning for developing cellular models of human disease. The latter will enable research into human diseases and may result in affordable therapies and cures for a variety of common diseases, such as cancer and heart disease, which afflict people all over the world. Finally, some have pointed out that it is not clear whether cloning research is necessarily more labor intensive than experiments on cells and tissues now done in animals.
Another concern is that because cloning is an asexual way of reproducing it would decrease genetic variation among offspring and, in the long run, might even constitute a threat to the human race. The gene pool may narrow sufficiently to threaten humanity's resistance to disease. In response, it has been argued that if cloning becomes possible, the number of people who will choose it
