    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….
