Human Brain Organoid Transplantation: Testing the Foundations of Animal Research Ethics
Alongside in vitro studies, researchers are increasingly exploring the transplantation of human brain organoids (HBOs) into non-human animals to study brain development, disease, and repair. This paper focuses on ethical issues raised by such transplantation studies. In particular, it investigates the possibility that they might yield enhanced brain function in recipient animals (especially non-human primates), thereby fundamentally altering their moral status. I assess the critique, raised by major voices in the bioethics and science communities, according to which such concerns are premature and misleading. I identify the assumptions underlying this skeptical critique, and mention some objections against them, followed by some possible replies. I proceed to argue that the skeptical position is ultimately implausible, because it presupposes an unreasonably high standard of full moral status. My argument appeals to David DeGrazia’s idea of a “borderline person”, and to the need for consistency with existing animal research regulations. I outline the practical implications of my view for the conduct of studies that might result in the development of full moral status in a transplanted animal. I also discuss some of the ethical implications of animal enhancement (particularly of rodents) below the threshold associated with full moral status. I conclude that far from being premature, further debate on these issues is urgently needed to help clarify the prospects that a neural chimera might attain full moral status in the foreseeable future, and the level of quality of life required to make it acceptable to knowingly create such a being via HBO transplantation.
期刊介绍:
Neuroethics is an international, peer-reviewed journal dedicated to academic articles on the ethical, legal, political, social and philosophical questions provoked by research in the contemporary sciences of the mind and brain; especially, but not only, neuroscience, psychiatry and psychology. The journal publishes articles on questions raised by the sciences of the brain and mind, and on the ways in which the sciences of the brain and mind illuminate longstanding debates in ethics and philosophy.
