IVF researchers produce human embryos from 3 donors
October 25, 2012
Researchers in the US and England are reporting initial success in experiments in which they produced human embryos from three adult donors.
The experiments, reported in Nature magazine, used in vitro fertilization techniques to take DNA from a mother and father, but insert it in an egg furnished by another woman. The technique could be used, the scientists explained, to avoid diseases carried by the mother’s mitochondria, which is contained in the egg cell.
Researchers said that all of the embryos produced in the experiments appeared normal. The embryos were destroyed, however, before being implanted in a woman’s uterus.
