Researchers said Wednesday they used a cloning technique to create human embryos that were close genetic copies of the people from which they were derived—a potentially significant breakthrough in the quest to develop patient-specific stem cells to treat serious diseases.



Scientists involved in the experiment, which was published in the journal Nature, created 13 early-stage human embryos that were partial genetic clones of diabetic patients. The copies were not identical, as each embryo carried three sets of chromosomes—an extra set. That means they were abnormal and wouldn't have been viable if implanted in a womb and carried to term.

If the technique is ever to become a viable treatment, the researchers would have to eliminate the extra set of chromosomes and effectively create an embryonic human clone.
