New breakthrough towards infertility treatment. Test on mice, with the same technique used for Dolly the sheep (ANSA) Researchers from the American University of Health and Science in Oregon have shed light on the mechanisms underlying a technique that involves the transfer of the nucleus of a cell of the skin.
Once implanted, the skin cell's nucleus discards half of its chromosomes, a key step that prepares the egg to be fertilized by the sperm. Finally, the researchers proceeded with in vitro fertilization to obtain a viable embryo, which possesses the chromosomes of both parents.
