Despite the monkey success, "we're still far off to start dreaming about translating this technique to humans," [Jose] Cibelli [of Michigan State University] said. That's because the reported results were very inefficient, requiring many eggs to produce stem cells, he said.The egg dearth will continue to thwart human cloning in the immediate future, creating much pressure among human cloners to gain access to eggs by any means necessary. In the coming years, we must be ever-ready to act to thwart the creation of a human egg commodities market that would exploit destitute women.
Still, the work shows monkeys can be used to study the potential ofproduced through cloning, Cibelli said. "That's a terrific tool."
In cloning to obtain stem cells, DNA from an adult animal is inserted into an unfertilized egg. The egg is grown into an early embryo, from which stem cells are extracted. These stem cells, and the tissue that develops from them, will be a genetic match to the source of the DNA.Hello Kansas City Star and others: See how it's done? It isn't that tough to be accurate in your reportage.
The idea of doing this in people is controversial because the embryos have to be destroyed to obtain the stem cells.
