Cloned the first human embryo with cells taken from an adult

In 1997 , scientist January Vilmut drew the attention of the whole world , he announced the first successful cloning using differentiated cells from an adult animal . Since then , scientists have tried to create cloned human embryo by the same technique , using differentiated cells from an adult . Now , they really worked , that would be an important step for organ transplants .

Last year , scientists reported progress in creating a cloned embryo . These scientists used differentiated cells taken from a fetus and a baby 8 months . This result was published in the journal Cell Stem Cell , where this technique was carried out using the somatic cells from two adult males , aged 35 and 75 years .

The technique used is the same as the benefit of sheep turned out . This technique involved two stages, initially took the nucleus of somatic cells to some glands of a sheep 's milk , and some of the unfertilized egg , whose nucleus was removed . Somatic cell nucleus joined the unfertilized egg cell by an electrical shock .

Currently, the stem cells are also obtained through the technique 'in vitro ' as well as cells from an adult, but both of these techniques have their drawbacks . Science has made it possible not only artificial fertilization , but also a transplant from a fertilized egg to the uterus in another surgical intervention in the germ and other manipulations , but all these have opened numerous ethical debates .
