somatic cell nuclear transfer

Cloning in which the nucleus of a somatic—i.e., non-germinal/reproductive—cell is transferred into an egg from which the nucleus has been previously removed, in order generate an embryonic stem-cell line, which has the advantage of pluripotency—i.e., the ability to differentiate along multiple pathways except the reproductive pathway

somatic cell nuclear transfer

In cloning, the transfer of genetic material from a differentiated, adult cell into an egg.

Somatic cell nuclear transfer is also known as therapeutic cloning.
The controversy surrounds a bill that seeks to outlaw therapeutic cloning, also known as somatic cell nuclear transfer. In therapeutic cloning, the nucleus of a woman's unfertilized egg is removed and replaced with the nucleus of another cell from a human body.
Canada, under the jurisdiction of the Assisted Human Reproduction Agency (within the Canadian Institutes for Health Research), allows use of the excess embryos from in vitro fertilization to be used for embryonic stem cell derivation, but does not yet allow somatic cell nuclear transfer. Sweden allows somatic cell nuclear transfer research.
The third technique, also known as "cloning," is to derive embryonic stem cells via somatic cell nuclear transfer. A complete set of genetic material (all 46 chromosomes that reside within the nucleus of a somatic cell) is transferred into an enucleated female egg (which normally contains half the total complement of chromosomes).

There are different techniques by which cloning might proceed (66) but the only kind of cloning currently considered viable is known as "somatic cell nuclear transfer." (67) This procedure involves removing the nucleus from an oocyte (of person 1), substituting the nucleus from a somatic (or "body" or non-germ) cell from someone else (person 2), and stimulating the cell with an electrical charge.

The ability to reproduce individuals through somatic cell nuclear transfer has been accomplished in at least five species, the latest being that of the cat.
