"Rudolf Jaenisch: In vitro fertilization, the embryos has a unique combination of genes that has not existed before, and it has a high potential to develop into a normal baby, healthy baby when implanted. In therapeutic cloning, the embryo has identical combination of genes as a donor, has no conception. Therefore the cloned embryo does not represent the creation of new life, but rather reprogramming and rejuvenation of an existing cell from your body. One could argue it's a special form of transplantation. The cloned embryo has a very low, exceedingly low potential to ever develop into a normal baby, because of the overwhelming problems which is associated with reproductive cloning. So the generation of embryonic stem cells from cloned (Inaudible) for the purpose of therapeutic cloning would appear to pose fewer ethical problems than the generation of embryonic stem cells from in vitro fertilized embryos, and the majority in this country certainly supports that."
