Cloning by nuclear transfer using mammalian somatic cells has enormous potential application. (biomedcentral.com)
Because cattle are a species widely used for nuclear transfer studies, and more laboratories have succeeded in cloning cattle than any other specie, this review will be focused on somatic cell cloning of cattle. (biomedcentral.com)
Somatic cell cloning (cloning or nuclear transfer) is a technique in which the nucleus (DNA) of a somatic cell is transferred into an enucleated metaphase-II oocyte for the generation of a new individual, genetically identical to the somatic cell donor (Figure 1 ). (biomedcentral.com)
Currently, the efficiency for nuclear transfer is between 0-10%, i.e., 0-10 live births after transfer of 100 cloned embryos. (biomedcentral.com)
Various strategies have been employed to modify donor cells and the nuclear transfer procedure in attempts to improve the efficiency of nuclear transfer. (biomedcentral.com)
Although the efficiency of nuclear transfer has been dramatically improved from the initial success rate of one live clone born from 277 embryo transfers [ 1 ], none of the aforementioned efforts abolished the common problems associated with nuclear transfer. (biomedcentral.com)
These observations suggest that further studies on nuclear reprogramming are needed in order to understand the underlying mechanisms of reprogramming and significantly improve the ability of the differentiated somatic nuclei to be reprogrammed. (biomedcentral.com)
For the most part, cloning is achieved through a process known as somatic cell nuclear transfer (SCNT). (syfy.com)
Somatic-cell nuclear transfer, the technique by which Dolly was created, was first used 40 years ago in research with tadpoles and frogs. (who.int)
if it implants and the pregnancy goes to term, the resulting individual will carry the same nuclear genetic material as the donor of the adult somatic cell. (who.int)
However, an animal created through this technique would not be a precise genetic copy of the source of its nuclear DNA because each clone derives a small amount of its DNA from the mitochondria of the egg (which lie outside the nucleus) rather than from the donor of cell nucleus. (who.int)
Scientists were initially interested in somatic-cell nuclear transfer as a means of determining whether genes remain functional even after most of them have been switched off as the cells in a developing organism assume their specialized functions as blood cells, muscle cells, and so forth.

Analysis of eight canine-specific microsatellite loci confirmed that the cloned dogs were genetically identical to their donor dog. (nature.com)
When the one-cell embryo duplicates its genetic material, both cells of the now two-cell embryo are genetically identical. (wptv.com)
When they in turn duplicate their genetic material, each cell at the four-cell stage is genetically identical. (wptv.com)
This pattern goes on so that each of the trillions of cells in an adult is genetically exactly the same - whether it's in a lung or a bone or the blood. (wptv.com)
Even while clones are genetically identical, their phenotypes - the characteristics they express - will be different. (wptv.com)
Thus, the clone would be genetically identical to the nucleus donor only if the egg came from the same donor or from her maternal line. (who.int)
Beyond this scientific interest, the commercial concern in animal cloning focuses on replicating large numbers of genetically identical animals, especially those derived from a progenitor that has been modified genetically. (who.int)
As the fertilized egg divides from one cell into two, physicians can separate these two cells and implant each one of them into a woman's uterus to generate two genetically identical children. (jcpa.org)

That's why Father Pacholczyk, director of education at the National Catholic Bioethics Center in Philadelphia, said that the efforts to help people understand the immorality of embryo reserch, including human cloning, must focus on humanizing the issue and appreciating our own embryonic origins, not just on the desired results of embryonic or other types of stem-cell research. (archstl.org)
The predominant bioethical concern arising from this technology is that the blastocyt-stage embryo must be destroyed in the process of isolating and separating the embryonic stem cells from the inner mass region of the pre-embryo. (jcpa.org)

But it is perhaps not auspicious to quote him for purposes of the scientific debates on human cloning, because Ramsey agreed with and supported the scientific myth of the "pre-embryo" 47 made famous by Jesuit Richard McCormick and frog embryologist Clifford Grobstein. (lifeissues.net)
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)
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)

That way when these so-called haploid cells come together at fertilization, they produce one cell with the full complement of DNA. (wptv.com)

While cloning is still largely the stuff of science fiction, we've actually got a pretty good handle on the science of it. (syfy.com)

So it is unlikely that the cells would be viable. (wikiquote.org)
Let's say that one in a thousand cells were nevertheless viable, practical issues come into play. (wikiquote.org)

In addition, specific proteins or biological substances can be added to these stem cell cultures to transform them in the laboratory into a large variety of specialized cell types, such as nerve, liver, muscle, bone, and blood cells. (jcpa.org)
