The possibilities of human cloning have raised controversies. These ethical concerns have prompted several nations to pass laws regarding human cloning. Two commonly discussed types of human cloning are therapeutic cloning and reproductive cloning. Therapeutic cloning would involve cloning cells from a human for use in medicine and transplants.
Human cloning is the creation of a genetically identical copy of a human. The term is generally used to refer to artificial human cloning, which is the reproduction of human cells and tissues. It does not refer to the natural conception and delivery of identical twins. The possibility of human cloning has raised controversies. These ethical ...
High fetal and neonatal death make the process very inefficient. Resulting cloned offspring are also plagued with development and imprinting disorders in non-human species. For these reasons, along with moral and ethical objections, reproductive cloning in humans is proscribed in more than 30 countries. [31] Most researchers believe that in the ...
Current human cloning methods need to use the somatic cell nuclear transfer (SCNT), which requires an unfertilized egg from a female donor to have its nucleus removed, resulting in an enucleated egg. DNA from the subject being cloned would need to be extracted and electronically fused together with the enucleated egg. A surrogate mother needs ...
[9] [10] [11] The five cloned embryos were later destroyed, [10] [11] [12] In January 2008, Wood and Andrew French, Stemagen's chief scientific officer in California, announced that they had successfully created the first five mature human embryos using DNA from adult skin cells, aiming to provide a less-controversial source of viable embryonic ...
Scientists are pioneering and refining three techniques in their attempts to revive lost and rare species: cloning, genetic engineering, and traditional back breeding, a form of selective breeding ...
The UN Declaration on Human Cloning, as it is named, calls for all member states to adopt a ban on human cloning, which it says is "incompatible with human dignity and the protection of human life." The US , which has long pushed for a complete ban, voted in favor of the statement while traditional ally Britain , where therapeutic cloning is ...
