Does Human Cloning Produce An Embryo?
In February 1997, Dr. Ian Wilmut and his team startled the scientific world by showing that the nucleus from an adult sheep's body cell could be used to produce a developing embryo that would grow into another, genetically identical sheep. There was no doubt whatever that this process ("somatic cell nuclear transfer") produces an embryo of the relevant species. As Dr. Wilmut said in his groundbreaking article: "The majority of reconstructed embryos were cultured in ligated oviducts of sheep... Most embryos that developed to morula or blastocyst after 6 days of culture were transferred to recipients and allowed to develop to term," etc. [I. Wilmut et al., "Viable offspring derived from fetal and adult mammalian cells," 385 Nature 810-813 (Feb. 27, 1997)]
Now that the discussion has turned to humans, political spokespersons for the biotechnology and pharmaceutical industries have decided to engage in a curious avoidance of the fact that somatic cell nuclear transfer using a human nucleus would produce a human embryo. There seem to be two reasons for this:
a. some spokespersons maintain -- contrary to scientific evidence, the findings of the NIH Human Embryo Research Panel, and current federal law on embryo research -- that no human embryos should be called "embryos" for the first two weeks of existence.1
b. because cloned embryos are seen as such useful research material for destructive experiments, current restrictions on embryo research etc. must be evaded by denying that an embryo produced by cloning deserves the name.
Thus euphemisms and misleading or inaccurate terms ("totipotent cell," "clump of embryonic cells," "unfertilized oocyte," etc.) have entered the political discussion. They are employed to conceal the fact that researchers want to be allowed to use cloning to produce and destroy human embryos. Biotechnology groups claim to oppose the cloning of "human beings" or "persons" -- but they reserve the right to conduct cloning experiments on human embryos and fetuses, so long as none is allowed to survive to live birth.
Fortunately, one can cut through the political evasions by looking at the professional literature -- including writings by those who support cloning of embryos for research purposes:
"One potential use for this technique would be to take cells -- skin cells, for example -- from a human patient who had a genetic disease... You take these and get them back to the beginning of their life by nuclear transfer into an oocyte to produce a new embryo.
Embryonic stem cells research has challenged the moral ethics within human beings simply because the point at which one is considered a “human,” is still under debate and practically incapable to make a decision upon.
Understanding the facts as well as procedures between the many different types of cloning is very crucial. When everything boils down there are three types of cloning known as DNA cloning, therapeutic cloning and reproductive cloning. DNA cloning is the copying of a gene in order to transfer it into another organism which is usually used by farmers in most of their crops. Therapeutic cloning is the use of stem cells used to help take the place of whatever cell is missing which is potentially used to help the ill. Stem cells contain the potential to grow and help replace the genes that are missing in order to fix whatever is genetically wrong with your body or any genes that you may be missing. Reproductive cloning actually produces a living animal from only one parent. The endless possibilities and perhaps hidden motives of using genetic engineering are what divide as well as destroy the scientific community’s hope for passing laws that are towards pro cloning. Many people within soci...
DNA is fully operational its human, “ embryos aren’t merely biological tissues or clusters of cells; they are the tiniest of human beings” (C.B.H.D. 2). Additionally, research on embryos is a violation of human rights and there is no greater good by doing so in the name of medicine. There have been gross violations of human rights in the past and destruction of an embryo to salvage ...
...ns of a morally questionable nature. It is necessary that our practices remain ethical and that we uphold the value of a human life, as this is the cornerstone of human society. Embryonic stem cell research is one such operation that forces scientists, policy makers, and the larger society to define what constitutes a human life and to find an answer to the crucial question: Is it morally acceptable to violate the rights of a human life for the for the sake of medical progress?
Cloning is a recent innovative technique the National Institute of Health defines as a process employed to produce genetically identical copies of a biological entity. Depending on the purpose for the clone, human health or even human life can be improved or designed respectively. “Somatic cell nuclear transfer (SCNT) is the most common cloning technique. SCNT involves putting the nucleus of a body cell into an egg from which the nucleus has been removed."^1 From this technique, an embryonic cell is activated to produce an animal that is genetically identical to the donor. Today, human cloning still remains as a vision, but because of the success of Dolly, the lamb, researchers are becoming more confident in the ability to produce a genuine

Stem cell research has been a heated and highly controversial debate for over a decade, which explains why there have been so many articles on the issue. Like all debates, the issue is based on two different arguments: the scientific evolution and the political war against that evolution. The debate proves itself to be so controversial that is both supported and opposed by many different people, organizations, and religions. There are many “emotional images [that] have been wielded” in an attempt to persuade one side to convert to the other (Hirsen). The stem cell research debate, accompanied by different rhetoric used to argue dissimilar points, comes to life in two articles and a speech: “Should Human Cloning Be Allowed? Yes, Don’t Impede Medical Progress” by Virginia Postrel; “Should Human Cloning Be Allowed? No, It’s a Moral Monstrosity” by Eric Cohen and William Kristol; and “Remarks by Ron Reagan, Jr., to the 2004 Democratic National Convention” by Ron Reagan, Jr. Ethos, pathos, and logos are the main categories differentiating the two arguments.
A unanimous decision should be made on when to consider an embryo a human being that has morality. Until then I believe that the embryo is not close to a human life unless it has made it past the fourteen day period in which it is passed the twinning stage. So with this information I come to the conclusion that under specific regulations and laws, including the ones I mentioned in the summary, the cloning of embryos for biomedical research and obtaining stem cells should be deemed acceptable.
Within the past few years, scientist have made several breakthroughs with human stem cells. These breakthroughs have catapulted the issue of stem cell research into the middle of a national debate. Most people have no problem with the research itself, however the source of the stem cells (adult or human embryos) used in research is the primary cause of the debate. Some people feel that destroying an embryo is comparable to murder, even if the research it promotes may help people with serious illnesses. Other believe that an embryo is not a person and therefore research on an embryo is the same as research on any other group of cells.
Ever since the successful birth of Dolly on July 5, 1996, the scientific community as well as the public have been engulfed in the idea of reproductive cloning, its benefits, and its potential threats. This well-publicized event was a giant steppingstone in understanding and using the techniques of gene cloning and reproductive cloning. By using a technique known as Somatic Cell Nuclear Transfer, scientists at the Roslin Institute removed the nucleus from an oocyte (unfertilized egg), and then fused this newly enucleated cell with a donor cell (with complete nucleus). This new embryo was then implanted into the womb of a surrogate mother ewe. In total, out of 277 fused cells, 29 successfully developed into embryos, while only one of these resulted in a successful live birth (a total success rate of 0.4%) (Wong, 202). Dolly was the first living mammal to be cloned by this fast and accurate process of somatic cell nuclear transfer, but was by no means the first animal to be cloned. The first...
Spearmann thought of cloning as a way to study cell differentiation. Briggs and King used the technique of nuclear transfer on amphibians and it was successful (Campbell). “Subsequently John Gurdon demonstrated the potential to reprogram differentiated cells by producing adult Xenopus using epithelial cells from developing tadpole intestine as nuclear donors,” says Alberio Campbell. Unfortunately, later studies show that this method of cloning tadpoles didn’t allow them to develop to the adult stage of life (Campbell). “The use of enucleated metaphase II oocytes as recipient cytoplasts proved more successful and in 1986 resulted in the production of live lambs using blastomeres from 8 to 16-cell stage embryos as nuclear donors,” says Campbell. This success in sheep was also used on other mammals such as cattle and swine. There were limitations to the technology. First, the “frequency development was very low”...
In recent years, the development of cloning technology in non-human species has led to new ways of producing medicine and improving our understanding of development and genetics. But what exactly is human reproductive cloning and how has this technology been developed? The term “cloning” refers more specifically to a process known as somatic cell nuclear transfer. In this process, the DNA from the cell of ...
been made possible but yet a majority of them have died in early stages of development or after birth according to the study of the cloned sheep, Dolly (Magalhães 1). Those who make it suffer from several defects acquired from birth (Magalhães 1). During recent experimentation it took scientist Ian Wilmut of the Roslin Institute in Edinburgh, Scotland, and his colleagues who created Dolly (a cloned sheep) 277 tries before they got a healthy, feasible lamb (Human Cloning 1). Due to the complication of human cloning even more deaths and deadly birth defects can be expected (Human Cloning 1). Even though human cloning has never been performed, one likely possibility is that babies born through this process will as well feature lethal birth defects (Magalhães 1).
