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)
In this procedure, the nucleus of an egg cell is removed and replaced by the nucleus of a cell from another adult. (eurostemcell.org)
In Dolly's case, the cell came from the mammary gland of an adult ewe. (eurostemcell.org)
After being inserted into the egg, the adult cell nucleus is reprogrammed by the host cell. (eurostemcell.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)
For example, stem cells could be generated using the nuclear transfer process described above, with the donor adult cell coming from a patient with diabetes or Alzheimer's. (eurostemcell.org)

Almost 'every other week there's another interesting finding of adult (stem) cells turning into neurons or blood cells or heart muscle cells,' notes molecular biologist Eric Olson at the University of Texas Southwestern Medical Center in Dallas. (freerepublic.com)
Unfortunately, it seems every other week there's also another article in the popular press claiming adult stem cells range from nearly worthless to utterly worthless. (freerepublic.com)
Ironically, the original motivation for the massive disinformation campaign is precisely the relative scientific superiority of adult stem cells. (freerepublic.com)
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)
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)
The most valuable cells for regenerative endodontics are postnatal or adult stem cells. (bvsalud.org)

Then, the researchers grafted the reprogrammed cells into the brains of 2- to 3-year-old, male cynomolgus monkeys ( Macaca fascicularis ) that had been treated with the neurotoxin MPTP, which kills dopamine-releasing neurons and results in PD-like movement defects. (the-scientist.com)
