Researchers at Oregon Health & Science University (OHSU) have developed a remarkable new way for making human body cells behave like egg cells—a technique that could change the course of the future of ...

Eggs contain 23 chromosomes needed for human development, which is half the usual number, because the sperm that fertilizes the egg will contribute the other 23 chromosomes. But skin cells and other ...

WASHINGTON (AP) — 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 ...

The new method offers researchers a powerful new platform to investigate the molecular mechanisms that control oogenesis, the process by which egg cells develop, and lays important groundwork for ...
