Human Eggs Aren’t Cheaper By The Dozen
Looks like a bunch of scientists have been trying to use animal eggs to create human stem cells. But it doesn’t quite work. I wonder what happens if they use their procedure on human eggs — ie. take a human egg, empty it out, squirt in a different human nucleus to create an embryo, and count the cell divisions. When they did this with mouse eggs, cells stopped dividing after just one split. Rabbit cells divided for a while, but then stopped at a certain point in embryo formation. I wonder if they tried monkey/chimp/gorilla eggs…? But then I assume those eggs are almost as difficult to obtain as human ones….
