These scientists destroyed the embryos and derived stem cell lines. (nationalrighttolifenews.org)
Most embryos…formed one or two pronuclei at the time of removal from TSA, whereas a slightly higher portion of embryos cleaved…suggesting that some SCNT embryos did not exhibit visible pronuclei at the time of examination… Most cleaved embryos developed to the eight-cell stage…but few progressed to compact morula…and blastocyst. (nationalrighttolifenews.org)
Activation of embryonic genes and transcription from the transplanted somatic cell nucleus are required for development of SCNT embryos beyond the eight-cell stage…Therefore, these results are consistent with the premise that our modified SCNT protocol supports reprogramming of human somatic cells to the embryonic state. (nationalrighttolifenews.org)
A story in News.Com.Au-which runs stories from several Australian newspapers celebrates the cloning breakthrough because it means no embryos are used in the process! (nationalrighttolifenews.org)
But it is an important step in research because it doesn't require the use of embryos in creating the type of stem cell capable of transforming into any other type of cell in the body. (nationalrighttolifenews.org)
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)
Scientists have applied somatic cell nuclear transfer to clone human and mammalian embryos as a means to produce stem cells for laboratory and medical use. (asu.edu)
And now Washington joins the infamous list with Senate Bill 5594, a thoroughly disingenuous piece of legislation that purports to outlaw the cloning of human beings, but by manipulating language and redefining terms, actually permits human cloning and gestation of the resulting cloned embryos through the ninth month. (cbc-network.org)
It is further speculated that those who support human embryonic stem cell research are also seeking human embryos for the purposes of human cloning. (all.org)
The stem cells suits human needs, does not cause harm and can be obtained from both adult and fetal does not conflict with religious beliefs, it has tissues, umbilical cord and early embryos. (who.int)
Unicellular for those cells that are derived from human organisms are primed to replicate (clone) pre-embryos, which seem to have a high themselves by nature. (who.int)
Some prohibit only cloning for reproductive purposes and allow the creation of cloned human embryos for research, whereas others prohibit the creation of cloned embryos for any purpose. (who.int)

In therapeutic cloning, the blastocyst is not transferred to a womb. (eurostemcell.org)
Another long-term hope for therapeutic cloning is that it could be used to generate cells that are genetically identical to a patient. (eurostemcell.org)
To date, no human embryonic stem cell lines have been derived using therapeutic cloning, so both these possibilities remain very much in the future. (eurostemcell.org)
Therapeutic cloning, which creates embryonic stem cells . (medlineplus.gov)
If the cloned human organism is to be experimented upon and destroyed, the process is often called "therapeutic cloning. (cbc-network.org)
This paper's main objective is to support the argument that embryo's cloning for one's self to serve as the stem cells' source for purposes of therapy should be considered morally permissible for people who want to prolong lives via this type of therapeutic option . (premiumessays.net)
As such, when a person opts to clone their embryo in order to produce stem cells that can be used for therapeutic purposes that will prolong life, they violate one of these moral principles which entail protecting human life as a duty. (premiumessays.net)
5. In 2001, France and Germany requested the United Nations General Assembly to develop international conventions on human reproductive cloning, therapeutic cloning and research on stem cells. (who.int)
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)
This led to the development of therapeutic cloning as a source for genetically matching replacement cells for patients with degenerative diseases. (ed.ac.uk)
However, therapeutic cloning depends on the availability of human eggs, which are in very limited supply. (ed.ac.uk)
Yet, human embryonic stem cell research has thus far been unsuccessful in the quest to develop any therapeutic treatments. (all.org)
Therapeutic cloning possesses enormous potential for revolutionizing medical and thera- peutic techniques. (who.int)
This is therapeutic cloning. (who.int)
This cell then has therapeutic cloning: the global the capacity to divide and grow into an exact replica of the original from whom the debate somatic cell was taken. (who.int)
In particular, scientific developments in areas such as iPS cells open new possibilities of research and, at mid term, of therapeutic applications, but they also bring new ethical challenges and problems requiring further reflection and debate. (lifeissues.net)

But they showed, for the first time, that it is possible to create cloned embryonic stem cells that are genetically identical to the person from whom they are derived. (nationalrighttolifenews.org)
The American Medical Association (AMA) defines human cloning as genetically identical organism's production through a process of somatic cell's nuclear transfer (SCNT). (premiumessays.net)
A clone is a group of genetically identical cells or organisms derived from a single cell or individual. (msdmanuals.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)

Cloning, or somatic cell nuclear transfer (SCNT), is the technique used to produce Dolly the sheep, the first animal to be produced as a genetic copy of another adult. (eurostemcell.org)
Once the SCNT is done, the cloning is over. (nationalrighttolifenews.org)
The cloning is completed when the SCNT is accomplished. (nationalrighttolifenews.org)
Somatic cell nuclear transfer (SCNT) is a technology applied in cloning, stem cell research and regenerative medicine. (asu.edu)
The primary cloning technique is called "somatic cell nuclear transfer" (SCNT). (cbc-network.org)
If the authors of this bill really meant what they appear to have written, their legislation would ban all human cloning, since as we have seen, biologically, a new human organism, that is, a new human being, comes into existence with the completion of SCNT. (cbc-network.org)
This is junk biology since implanting isn't the act of asexual reproduction: SCNT cloning is. (cbc-network.org)
SCNT refers to a process that entails transferring somatic cells of an existing organism into the oocyte where the nucleus came from (National Human Genome Research Institute Para 1). (premiumessays.net)
Again, Saunders is referring to SCNT as "THE" cloning procedure, when there are many other ways to clone a human being as well, and he is scientifically mis-defining the product of SCNT (i.e., the cloned human embryo). (lifeissues.net)

That is what New Jersey legislators did when they passed and then Governor James McGreevey signed S-1909 last year, a law that was sold to the public as outlawing human cloning but which actually permits the creation of cloned human life, and its implantation and gestation up to and including the very moment prior to the emergence of the cloned baby from the birth canal. (cbc-network.org)

Going from engineered cells to whole organism has been especially well established in mice, and [there's] no obvious reason why it would fail in other mammals. (nationalgeographic.com)
However, cloning need not only be used to create a whole organism. (msdmanuals.com)

To produce Dolly, the cloned blastocyst was transferred into the womb of a recipient ewe, where it developed and when born quickly became the world's most famous lamb. (eurostemcell.org)
The most famous clone was a Scottish sheep named Dolly. (medlineplus.gov)
Since the 1996 birth of Dolly the sheep, the world's first cloned mammal, scientists have greatly expanded and improved on cloning techniques. (nationalgeographic.com)
However, his results and improved methods inspired researchers at The Roslin Institute to use nuclear transfer to clone sheep and produce Dolly the Sheep, the first animal to be cloned from an adult cell. (ed.ac.uk)
Together, Gurdon's and the Dolly team's successes introduced the concept of reprogramming the DNA of specialized cells to be able to make new organisms or new stem cells. (ed.ac.uk)
In the now-famous "Dolly" experiments, cells from a sheep (donor cells) were fused with unfertilized sheep eggs from another sheep (recipient cells) from which the natural genetic material was removed by microsurgery. (msdmanuals.com)
As expected, Dolly was an exact genetic copy of the original sheep from which the donor cells were taken, not of the sheep that provided the eggs. (msdmanuals.com)
Although many species produce clonal offspring in this fashion, Dolly, the lamb born in 1996 at a research institute in Scotland, was the first asexually produced mammalian clone. (who.int)
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)

2. Nuclear transfer is a technique used to duplicate genetic material by creating an embryo through the transfer and fusion of a diploid cell in an enucleated female oocyte.2 Cloning has a broader meaning than nuclear transfer as it also involves gene replication and natural or induced embryo splitting (see Annex 1). (who.int)
7. "[footnote 16]: The cloning procedure supplies the oocyte with a complete set of chromosomes, all of which are contained in the nucleus which is transferred into the denucleated oocyte. (lifeissues.net)

The second way to reproduce is a strictly human invention - known as "asexual" reproduction - or more commonly, cloning. (cbc-network.org)
Cloning of a human being" means asexual reproduction by implanting or attempting to implant the product of nuclear transplantation [e.g., an embryo] into a uterus or substitute for a uterus with the purpose of producing a human being. (cbc-network.org)

After many divisions in culture, this single cell forms a blastocyst (an early stage embryo with about 100 cells) with almost identical DNA to the original donor who provided the adult cell - a genetic clone. (eurostemcell.org)
Instead, embryonic stem cells are isolated from the cloned blastocyst. (eurostemcell.org)

Somatic cells are cells that have gone through the differentiation process and are not germ cells. (asu.edu)
It is the policy of Washington state that research involving the derivation and use of human embryonic stem cells, human embryonic germ cells, and human adult stem cells from any source, including somatic cell nuclear transplantation , is permitted upon full consideration of the ethical and medical implications of this research. (cbc-network.org)
Furthermore, it was predicted that a specialized DNA polymerase (originally called a tandem-DNA-polymerase) could extend telomeres in immortal tissues such as germ line, cancer cells and stem cells. (slideshare.net)

Reproductive cloning versus germ cell (egg, ovum). (who.int)

While stem-cell research holds enormous potential for treating or even curing some diseases, the cloning of a human being is morally and ethically unacceptable…Any attempt to clone a human being is in direct conflict with the public policies of this state. (cbc-network.org)
WHA50.37 of 1997 argues that human cloning is ethically unacceptable and contrary to human integrity and morality. (who.int)
WHA50.37, which states "the use of cloning for the replication of human individuals is ethically unacceptable and contrary to human integrity and morality. (who.int)

As if it were induced pluripotent stem cells, which really do turn skin into stem cells. (nationalrighttolifenews.org)
In 2006, Shinya Yamanaka and Kazutoshi Takahashi successfully reprogrammed specialised cells into induced pluripotent (iPS) cells. (ed.ac.uk)
But what is not getting such wide reporting is the use of pluripotent stem cells (as well as many other types of cells and genetic engineering techniques) for reproductive purposes . (lifeissues.net)

In this procedure, the nucleus of an egg cell is removed and replaced by the nucleus of a cell from another adult. (eurostemcell.org)
After being inserted into the egg, the adult cell nucleus is reprogrammed by the host cell. (eurostemcell.org)
The team at OHSU [Oregon Health and Science University], which disclosed its work in a paper published online by Cell, created embryonic stem cells by replacing the nucleus in an unfertilized human egg with the nucleus from a skin cell, then harvesting the resulting stem cells. (nationalrighttolifenews.org)
The nucleus of a body cell from the DNA donor is removed, and put into the place formerly occupied by the egg's nucleus. (cbc-network.org)
Starting with an intact cell (fresh or frozen) of the animal they'd like to clone, scientists first remove the nucleus, where DNA resides, and insert it into a hollowed-out egg cell of the same or a related species. (nationalgeographic.com)

The basic techniques of of the implanted nucleus, when it fully cloning have been known for some time, and develops. (who.int)
The nucleus of an adult somatic cell (such as a skin cell) is removed and transferred to an enucleated egg, which is then stimulated with electric current or chemicals to activate cell division. (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)

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)

increased public sensitivity and awareness together with the development of national regulations of governance of human cloning and embryo research in general. (lifeissues.net)
3. National regulations of governance of human cloning and embryo research in general adopted so far confirm the convergence of views of the refusal to adopt legislation or guidelines permitting reproductive cloning , while they still show variations on the legitimacy of human cloning carried out as part of research agendas. (lifeissues.net)

With that publication, "genome engineering of mammalian cells just took a big step forward," he says. (nationalgeographic.com)

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.
