HUMAN CLONING

The team of U.S. scientists claim to have successfullyusing cloning techniques to create fivehuman embryo. Of the five embryos, three of whom confirmed the cloningof the two men. This groundbreaking work done at La Stemagen Corp.Jolla, California using technique called SCNT (somatic cell nuclear transfer). Egg nucleustaken then filled somatic cell nucleus, in this case used skin cells.These techniques are used Ian Wilmut and his colleagues to create Dolly,The first cloned sheep. Eggs that have been filled these somatic cell nuclearcultivated in a nutritive environment to grow into an embryo. Afterfive days, the embryo is formed whichcomposed of a collection of about 150 cells.The embryos are not intended todeveloped into a fetus, but as a source of embryonic stem cells. Typestem cells that form on old embryos will develop into the fetus isvery useful because it can grow into bone, flesh, skin, and tissuebody. In this study, the researchers have not Stemagenextract embryonic stem cells from cloned embryos. However, they havesuccessfully proved that the embryo is the result of cloning becausehave the same DNA with a man who became donor. If this breakthroughproved to be correct, they will be recorded as the first researcher to successfully clone human embryos as a source of embryonic stem cells. "Wehope this will be a turning point for many studiesnext, "said Andrew French, head of the research team report success in the journal Stem Cells. Now they're focused oncell extract embryonic stem cells from cloned embryos.The success of a human embryo cloning results not which was first reported. The researchersEngland was able doing in 2005 and even until the embryo ismature cells to produce embryonic stem cells. However, until now noNone reported researchers managed to extract embryonic stem cellshumans. Korean scientist Hwang Woo-suk had claimed to be the first researcherthe extract of human embryonic stem cells. However, the success of theconsidered to lie in counterfeiting after data analysison scientific papers. Stem cells of embryonic cloning results can be usedto study the disease, drug response, even making organ transplantsthe patient needs. However, these studies also invite criticismregarding ethics. "(Cloning) produced in the laboratory to humandestroyed simply because the allegation that it would be useful bagiaAnother man, "said Richard Doerflinger. Cloning human embryos alsodistemper feared especially if more and more women whoasked to become an egg donor.
