Dear Emperor of the Universe,
Partially, the idea of cloning in order to yield organs has been
already tested. "Therapeutic cloning: (a.k.a. Somatic cell nuclear
transfer or research cloning): This starts with the same procedure as
is used in adult DNA cloning. The resultant embryo would be allowed to
grow for perhaps 14 days. It's stem cells would then be extracted and
encouraged to grow into a piece of human tissue or a complete human
organ for transplant. The end result would not be a human being; it
would be a replacement organ, or piece of nerve tissue, or quantity of
skin. The first successful therapeutic cloning was accomplished in
2001-NOV by Advanced Cell Technology, a biotech company in Worcester,
MA." (SOURCE: Religious Tolerance Website,

However, "But the fetuses were grown for that long only because
researchers have not yet found a way to harvest stem cells from a new
bovine embryo, said Robert Lanza, medical director at ACT." (SOURCE:
"The Next ACT in Clone Controversy" WIRED,
<http://www.wired.com/news/medtech/0,1286,53104,00.html>).
You could read about ACT's work in another Wired article, "Seven Days
of Creation" January 2004
<http://www.wired.com/wired/archive/12.01/clones.html?tw=wn_tophead_3>.
This, on the bottom line, was done on animals - except for skin
transplants (that are not exactly cloning). ""Experiments have already
been conducted using cows in which cloned embryos were implanted,
gestated to the early fetal stage, aborted, and their organs harvested
for transplantation." (SOURCE: "State of Cloning"
<http://www.nationalreview.com/lopez/lopez200401051346.asp>).
Lately, Prof. Panos Zavos of the Andrological Institute of America
<http://www.aia-zavos.com/index.html> claims to have being able to
clone an embryo, in order to create twins, from which one will be
developed into a full human being, and the other will be used, if
necessary, as a source for organs.
This will be done in a method called "Blastomere separation", or
twinning. It "involves splitting a developing embryo soon after
fertilisation of the egg by a sperm (sexual reproduction) to give rise
to two or more embryos.The resulting organisms are identical twins
(clones) containing DNA from both the mother and the father. Before
making his shock announcement, Dr Panos Zavos unveiled plans to seek a
woman prepared to receive a split embryo, half of which would be used
for "spare part" surgery." (SOURCE: ic Wales, "What is Cloning"

However, the plan, concieved with Dr. Paul Sainsbury, is highly
controversial, and has not been publically tried.

I hope this gave you a review of the current trends in cloning. I
recommend that you'll follow Google News on the question with the
keywords "therapeutic cloning":
