Unsettled Science

March 4, 2012

Every biology textbook that I have ever read stated that women are born with all the eggs they will ever have and their ovaries do not produce any more. It turns out that every biology textbook that I have ever read is wrong. From Scientific American.

A study led by Jonathan Tilly of the Massachusetts General Hospital overturns the decades-long idea that women are born with all the eggs they will ever have. It reports that women of reproductive age carry ovarian stem cells, meaning that they can produce new eggs. Tilly’s team, which made a similar finding in mice in 2004, also discovered that mouse eggs derived from such stem cells can indeed be fertilized.

Our colleagues at Nature Medicine, which is publishing the paper today online, created this four-minute video explaining the results. (Scientific American is part of Nature Publishing Group.)

There really is so much we don’t know.

Thanks to Walter Russel Mead for posting this.

Interesting first comment for this short article.

That’s great, just what the earth needs, more people, more fodder for future dole queues, now we can really go to town on over populating the planet…

Come on scientists, get your priorities right…

Greens really hate people.
