11.   Surprisingly, the survivors were female mice that had become pregnant soon after infection and were able to destroy the deadly cancer cells.

17.   The DNA used in that experiment was derived from cumulus cells, which surround developing eggs in the ovaries of female mice.

18.   The embryos were implanted in female mice for development.

19.   The first mice were created by inserting a human detoxifying gene into fertilized eggs which were then implanted into a female mouse.
