Scientists create first early human eggs from stem cells in fertility breakthrough
By

Summary
This article reports on a major scientific milestone: the development of the first early human eggs from stem cells (in vitro gametogenesis). It explains how researchers have successfully turned induced pluripotent stem cells (iPSCs) into early-stage human egg cells (oogonia), building on prior work in mice by Katsuhiko Hayashi. The piece covers the biology behind the process, the engineering challenges, and the validation steps required to confirm the achievement. It discusses the potential implications for fertility treatments, reproductive science, and ethical considerations surrounding lab-grown human reproductive cells.

· 3 pulledIn 2016, our collaborator Katsuhiko Hayashi demonstrated that mouse skin cells can be turned into 'induced pluripotent stem cells' (iPSCs, which are engineered cells capable of becoming any kind of cell in the body) and then turned into usable eggs.
These eggs produced healthy pups that lived normal lifespans and reproduced naturally, having healthy pups of their own.
This process, known as 'in vitro gametogenesis' (IVG), represents a major step forward in reproductive biology.
