Finally, and inexorably, a true professional scientist poses clearly challenging questions to his research colleagues, and to the scientific enterprise in general, about the dubious "scientific" justification for the current rush to clone human beings - for both "therapeutic" and for "reproductive" purposes. (lifeissues.net)
Ethically, since eventually all such "research" will be applied to people, he cautions against the abuse of women "egg" donors, and against the premature use of vulnerable sick human patients for testing supposedly "patient-specific" stem cells in supposed "therapies", pointing to the obvious violations of standard international research ethics guidelines such clinical trials would necessarily entail.

And he also agrees that if we don't find global agreement on human cloning, "we can probably expect dire consequences for the future of biomedical research and its impact on society at large. (lifeissues.net)
But he is equally concerned about the unethical aspects inherent in the rush to perform " therapeutic " human cloning research, including the abuses to all vulnerable human patients who would be required to participate in clinical trials. (lifeissues.net)
As he has questioned the HFEA before, would not the use of vulnerable human patients in clinical trials be premature, dangerous, and unethical given the already acquired knowledge in the research community that such supposed "patient-specific" stem cells would most probably cause serious immune rejection reactions in these patients?
