Oregon scientists used human skin cells to create fertilizable eggs, a step in the quest to develop lab-grown eggs or sperm to one day help people conceive. But the experiment resulted in abnormalities in chromosomes, prompting the Oregon Health & Science University team to caution it could take a decade of additional research before such a technique might be ready for trials in people. They are already working to improve the technique. The work was published Tuesday in the journal Nature Communications. It may offer lessons as scientists try to learn to create eggs and sperm for the infertile or to help same-sex couples have children genetically related to both partners.
Researchers turn human skin cells into eggs — but not yet usable ones
