The OAR proposal uses a
variation of therapeutic cloning called altered nuclear transfer (ANT) in which the nucleus of a donor cell (a skin cell, for example), containing the 30,000 genes of the genetic code, is altered in such a way that it produces an epigenetic factor, a protein called nanog.
But everyone who accepts these instruments becomes implausible when asking for a
ban of therapeutic cloning and projects the near end of the Western world.
Blackburn, a cell biologist at the University of California at San Francisco, charges she was released for speaking out in

The
value of therapeutic cloning has long been clear to Lanza, who did his early work with South African heart transplant pioneer Christiaan Barnard.
This is what makes the
return of therapeutic cloning such a gripping plot twist (see «Human stem cells made using Dolly cloning technique «-RRB-.
The lab results for iPS cells have been impressive so far, he says, «but if they do not have therapeutic value, they will be far from getting to the point of replacing the whole
idea of therapeutic cloning.»
