Cloned Human Embryo Can Serve as Embryonic Stem Cell Factory
“Scientists at the New York Stem Cell Foundation Laboratory have reprogrammed an adult human egg cell to an embryonic state using cloning technology and created a self-reproducing line of embryonic stem cells from the developing embryo.
In so doing, they have managed a feat that has at times been thought impossible, then inevitable, then completed, then incomplete and unfeasible. Their work is published today in Nature.
It is not the end-all experiment that scientists aiming to create embryonic stem cells have been hoping for — the embryos are not true clones, because the DNA of the stem-cell line does not match that of the patient who donated cells — but it is a step in that direction and addresses some of the problems that have flummoxed experiments.”
