Otherwise, such a treaty would not recognize the inherent human nature of the early human embryo or fetus until after birth , and thus cloning them and using them for research - both "therapeutic" and "reproductive" -- would not be banned, and women undergoing "infertility treatments" could surely be put in danger. (lifeissues.net)
Note that each and every individual "loophole" discussed below that permits human cloning by default (and most bills have literally dozens of such loopholes) thus permits it for both "therapeutic" and for "reproductive" human cloning. (lifeissues.net)
What deserves greater attention, however, is therapeutic cloning, a (potential) cloning application considered far more important to the biomedical and scientific communities and one far more ethically challenging. (reasons.org)

In the field of biotechnology, cloning is the process of creating cloned organisms of cells and of DNA fragments. (wikipedia.org)
The main reason for our oposition was that these techniques would be the first instance of deliberate changes to the germ line of children: the changes would be present in all cells of the body and would be transferred to descendants of girls created using the technique. (hgalert.org)
Tragically, however, in order to harvest stem cells from human embryos, the embryos must be destroyed. (reasons.org)

In their report on the work in the June issue of the journal Blood, the Johns Hopkins team demonstrated a clear similarity between how human embryonic stem cells specialize into blood cells and how blood cells develop in human embryos. (sciencedaily.com)
More and more we're learning that the genes that turn on in the embryo to make blood stem cells are the same genes that go wrong in cancer," he says. (sciencedaily.com)
These colonies can then also form the precursors of blood cells, in a structure similar to the yolk sac of human embryos. (sciencedaily.com)
The second method of cloning a human involves taking cells from an already existing human being and cloning them, in turn creating other individuals that are identical to that particular person. (benjaminbarber.org)
They attempted to create seventeen human embryos in a laboratory dish and when it had grown enough, separated them into forty-eight individual cells. (benjaminbarber.org)
Two of the separated cells survived for a few days in the lab developed into new human embryos smaller than the head of a pin and consisting of thirty-two cells each (Brownlee 24). (benjaminbarber.org)
The end may be in sight for the debate over "harvesting" human embryos for their stem-cells in the pursuit of possible medical cures. (stanguthrie.com)
Pan said the robotic cloning technique - as well as the broader science of micro-manipulation of cells - could have a wide range of applications in animal husbandry, including assisted reproduction and selective breeding. (scmp.com)
The subsequent discovery of promising alternative techniques for generating stem cells without creating or destroying embryos seemed to show that scientific progress would obviate the demand for cloning. (thenewatlantis.com)
This kind of cloning is today being performed at several scientific labs in the United States, despite the availability of alternative techniques that produce cells of nearly the same scientific and medical value but that require neither the creation nor destruction of human embryos.

Citizens disagree about whether we should destroy human embryos for their stem cells-and if so, which embryos, with whose money, under what regulatory guidelines. (eppc.org)
The holy grail of regenerative medicine-whatever one's ethical beliefs about destroying embryos-is to "reprogram" regular cells from one's own body so that individuals can be the source of their own rejection-proof therapies. (eppc.org)
That is to say, we risk turning developed cells into developing embryos, and thus risk engaging in the very activities of embryo destruction and human cloning that we seek to avoid. (eppc.org)
Far more controversial-and for good reason-are stem cells derived from destroyed human embryos. (eppc.org)
While less controversial, the stem cells produced by the new technique appear to be carcinogenic. (denialism.com)
Is it the idiotic assumption that we are already thinking about injecting these cells willy-nilly into embryos? (denialism.com)
The recent news that Japanese investigators have found a way to make pluripotent stem cells without either destroying human embryos or using cloned embryos is hard to overemphasize, if it pans out. (blogspot.com)
At the time they were mesmerised by dreams of cloning embryos and dissecting them for their stem cells. (blogspot.com)

On the other hand, if by "potential" one means that the human embryo is not a human being or human person yet , but might be later once it has been born (i.e., a "baby"), then that statement is both scientifically and philosophically incorrect. (lifeissues.net)
Thus to use the phrase "of an existing or previously existing human being" to refer to the product of human cloning would not be a scientifically accurate description of the cloned or genetically engineered human embryo -- thus creating yet another loophole in the bill or treaty. (lifeissues.net)

After all, large groups of cloned animals would help eliminate some of the variation that occurs in animal trials, since all of the monkeys would be expected to respond to a drug in the exact same way. (inverse.com)

Japanese Scientist To Clone Woolly Mammoth Within 5 Years! (singularityhub.com)

Clonaid's claim to have produced the first human clones propelled the ethical debate about human cloning to the headlines last December. (reasons.org)

Thus, while Ramsey agreed that there is a human being present immediately at fertilization, he did not agree that it was also a human embryo or a human person - the classic "pre-embryo" argument. (lifeissues.net)

In March, a surrogate mother gave birth to seven cloned piglets at the College of Artificial Intelligence at Nankai University in Tianjin. (scmp.com)

Zambidis and colleagues are currently using their model to study the next stage in blood cell development, which in a growing embryo involves blood cell precursors moving from the yolk sac into the liver, bone marrow and thymus. (sciencedaily.com)
The first way involves splitting an embryo into several halves and creating many new individuals from that embryo. (benjaminbarber.org)

The main issue as to whether or not human cloning is possible through the splitting of embryos began in 1993 when experimentation was done at George Washington University Medical Center in Washington D. C. There Dr. Jerry Hall experimented with the possibility of human cloning and began this moral and ethical debate. (benjaminbarber.org)
And their work is reigniting the ethical debate over human cloning of any kind. (cnn.com)

Pan, the founder of Clonorgan Biotechnology in Chengdu, said he used to create more than 1,000 clones by hand every day, a process that was so time-consuming and complicated that he developed back pain as a result. (scmp.com)
The Los Angeles Times has waded in to the junk biology game, assuring us that no embryos are threatened in human cloning-WHEN THE WHOLE POINT OF HUMAN CLONING IS TO CREATE AN EMBRYO! (nationalrighttolifenews.org)

Perhaps Ramsey would give other extraordinarily powerful arguments as to why human cloning is unethical, but he obviously would not be able to base it on his unscientific "pre-embryo" position. (lifeissues.net)
Creating a human by cloning is widely seen as unethical, is illegal in many countries, and is technically difficult. (msdmanuals.com)

This also might have explained why cloning is inefficient: only 1-3% of cloned embryos eventually develop into an adult clone. (rupress.org)

Cloning is commonly used to amplify DNA fragments containing whole genes, but it can also be used to amplify any DNA sequence such as promoters, non-coding sequences and randomly fragmented DNA. (wikipedia.org)

DARYN KAGAN, ANCHOR: Another story we're watching very closely today, the medical and moral debate over cloning. (cnn.com)
But if we are to make wise policy the stem cell/cloning arena, we need to step back, sort out the various scientific alternatives and moral issues, and search for a way forward that all citizens can embrace. (eppc.org)
To this end, we offer a detailed analysis of the stem cell/cloning question-where is the science, what are the political alternatives, and what moral obligations should guide us? (eppc.org)
Cloning technology, however, is perceived as having the potential for reproductive cloning, which raises serious ethical and moral concerns. (who.int)

This means that hundreds of human embryos would die to achieve a single live human clone birth. (reasons.org)

Different mitochondrial donation techniques involve transferring the nuclear DNA at different stages. (nhmrc.gov.au)

Though fraught with problems, reproductive cloning at least strives to reproduce a human being and, in principle, preserves the value of human life. (reasons.org)
Even Nature agrees that, "The technique is expensive, technically difficult and ethically fraught. (bioedge.org)

But mice cloned in this fashion eventually developed neck tumors. (denialism.com)

The main objection to the use of human cloning for reproductive purposes is that it would be contrary to human dignity as it would violate the uniqueness and indeterminateness of the human being. (who.int)
Human cloning for reproductive purposes is seen as having the potential to disrupt intergenerational relations and family structures, with major psychological, social and legal consequences for the individuals and communities concerned. (who.int)
Since then, many countries have adopted government decrees or introduced legislation to impose an explicit ban on human cloning for reproductive purposes. (who.int)
