Scientists propose interspecies cloning

It was nearly a decade ago that Jose Cibelli plugged his own DNA into a cow’s egg in a novel cloning attempt that was condemned as unethical by President Clinton and landed the Michigan State University researcher in a mess of controversy.

Even though Cibelli and his colleagues patented the so-called interspecies cloning technique, they soon abandoned the research as a failure and the uproar subsided.  Now the tempest is brewing all over again.

At least three respected teams of British scientists have reignited the moral debate over inserting human genes into animal eggs by proposing experiments similar to Cibelli’s.

Their goal is to eliminate the need for women to donate eggs for the cloning of human embryos, which they say will help them better understand the genetic causes of many diseases and design personalized medicines.

The few scientists actively pursuing human cloning are hobbled by a nearly nonexistent human egg supply. And each researcher will need thousands of them.
