Somatic Cell Transfer
In genetics and developmental biology, somatic cell nuclear transfer (SCNT) is a technique for cloning. It can be used in embryonic stem cell research, in which the process is often called "research cloning" or "therapeutic cloning." It can also be used in reproductive cloning.
The process
In SCNT the nucleus, which contains the organism's DNA, of a somatic cell (a body cell other than a sperm or egg cell) is removed and the rest of the cell is discarded. At the same time, the nucleus of an egg cell is removed. The nucleus of the somatic cell is then inserted into the enucleated egg cell. After being inserted into to the egg, the somatic cell nucleus is reprogrammed by the host cell. The egg, now containing the nucleus of a somatic cell, is stimulated in such a way that it begins to divide. After many mitotic divisions in culture, this single cell forms a blastocyst (an early stage embryo with about 100 cells) with almost identical DNA to the original organism.

Somatic Cell Nuclear Transfer (Therapeutic Cloning)
Cloning is the creation of multiple copies of a single molecule, cell, or virus. There are many different kinds of cloning, most of which are now commonplace in science. Cloning has allowed scientists to develop powerful new drugs and to produce insulin and useful bacteria in the lab. It also allows researchers to track the origins of biological weapons, catch criminals and free innocent people, and produce new plants and livestock to feed an undernourished world population.
Somatic Cell Nuclear Transfer (SCNT) or therapeutic cloning involves removing the nucleus of an unfertilized egg cell, replacing it with the material from the nucleus of a "somatic cell" (a skin, heart, or nerve cell, for example), and stimulating this cell to begin dividing. Once the cell begins dividing, stem cells can be extracted 5-6 days later and used for research. The AAMC supports on-going research into SCNT and has endorsed legislation that would allow such research to flourish.
Reproductive cloning, on the other hand, is intended to create human beings by cloning human embryos. The AAMC and the National Academy of Sciences recommend a ban on all forms of this type of cloning.

In the somatic cell nuclear tranfer technique, stem cells that are genetically identical with the cells of a recipient's own body could be derived. A somatic cell is any cell other than a sperm, egg, or cell that gives rise to a sperm or egg. The nucleus of the egg (containing its DNA) is removed and replaced with the nucleus (and its DNA) of a somatic cell (such as skin or blood) from the recipient. The egg containing the transferred nucleus is then encouraged to divide until it reaches the blastocyst stage, at which time the cells of the inner cell mass are removed and cultured. The resulting stem cells would be immunologically compatible with the recipient's own tissues because they would not contain DNA that produces proteins that the recipient's body would react to as "foreign".

Amendment 2
6. (5) "Human embryonic stem cell research," also referred to as "early stem cell research," means any scientific or medical research involving human stem cells derived from in vitro fertilization blastocysts or from somatic cell nuclear transfer. For purposes of this section, human embryonic stem cell research does not include stem cell clinical trials.
The amendment says "no cloning... can't break existing federal laws" but acknowledge SCNT as part of their research using embryonic cells. Is this a loophole?
