Scientists create human eggs in the lab, using skin cellstoggle caption Mitalipov laboratoryScientists have created human eggs containing genes from adult skin cells, a step that someday could help women who are infertile or gay couples have babies with their own genes but would also raise difficult ethical, social and legal issues. So scientists have been trying to create human eggs in the lab that carry the genes of people struggling to have children. The most common approach involves converting adult cells, such as skin or blood, into cells known as induced pluripotent stem, or iPS, cells. The closest anyone has come to success for eggs has been very primitive human egg cells that are too immature to be fertilized. Scientists could create eggs from a skin cell of one male partner and fertilize it with sperm from the other male partner.
