Once you’re done, you’re done. That’s the story women have been given for over sixty years: that they’re given a set of eggs at birth that cannot be replaced once they’ve been exhausted. This is the prevailing theory behind much of fertility treatment for women, as well.
But now one scientist has been able to isolate stem cells in human ovaries, stimulate them and put them inside a mouse ovary to produce new human eggs. The implications of this are enormous, both for fertility treatment and for the advancement of further stem cell research.
This is also possibly the dawn of a new era of an unthinking and unstoppable army clones, controlled by drones. But perhaps I’m getting ahead of myself….
