And in that time they've learned to transform stem cells into pretty much anything they wanted to - heart cells, liver cells, brain cells. But now a group of Japanese scientists has raised the bar by transforming mouse stem cells into mouse eggs. And not only do they look like eggs but they can be fertilized and developed into healthy mice.
