Both types of somatic cell nuclear transfer cloning reproduce the donor; the chosen destiny for the newly conceived clone defines the procedure … a short lifetime for a harvesting target (so called therapeutic cloning), or a long lifetime as an individual identical twin (so called reproductive cloning).
Why is it important to realize that an embryo is a human being at an early age along a continuum of individual life? Because therapeutic cloning coupled with embryonic stem cell harvesting aim to cannibalize individual human life. Defenders of therapeutic cloning are seeking to characterize that ‘type’ of human cloning as non-reproductive, but the truth is, ALL somatic cell nuclear transfer cloning is reproductive, conceiving an individual human life. Defenders and promoters of therapeutic cloning deny that the embryonic individual life is a human being at that age of a lifetime begun at conception.
Tha AMA clearly support killing the newly conceived individual human being before further ages can be reached along the continuum of life begun at a designer, cloning, conception ... because of their utilitarian value regardless of their humanity.
The science of Embryology holds as fundamental truth that even an embryo no bigger than a grain of sugar is an individual human life. Is it acceptable to kill that individual for body parts? If it is, that's cannibalism as surely as eating body parts or whole embryos for medical cures. The AMA is squarely endorsing cannibalism, the cannibalizing of individual human embryos conceived specifically for their body parts, their stem cells.
