From Stem Cells To Eggs (And Beyond)

Transcript

IRA FLATOW, HOST:

Up next, turning stem cell into mouse eggs. Scientists have been growing stem cells in the lab for nearly 15 years now. 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.

Scientists Use Stem Cells To Create Eggs In Mice

Transcript

RENEE MONTAGNE, HOST:

Scientists have, for the first time, used stem cells to create eggs in mice. This long-sought breakthrough raises the possibility of some day doing the same thing to help treat infertility in people. As NPR's Rob Stein reports, that's generating a lot of debate.

Scientists Create Fertile Eggs From Mouse Stem Cells

Originally published on Thu October 4, 2012 8:45 pm

Each of these mouse pups was born from an egg scientists created using embryonic stem cells. It's possible the technology could change future treatment for human infertility.
Katsuhiko Hayashi

Scientists in Japan report they have created eggs from stem cells in a mammal for the first time. And the researchers went on to breed healthy offspring from the eggs they created.

While the experiments involved mice, the work is being met with excitement — and questions — about doing the same thing for humans someday.
