Advancing Neuroregenerative Medicine: a Call for Expanded Collaboration Between Scientists and Ethicists


To date, ethics discussions about stem cell research overwhelmingly have centered on the morality and acceptability of using human embryonic stem cells. Governments in many jurisdictions have now answered these “first-level questions” and many have now begun to address ethical issues related to the donation of cells, gametes, or embryos for research. In this commentary, we move beyond these ethical concerns to discuss new themes that scientists on the forefront of NRM development anticipate, providing a preliminary framework for further discussion between scientists and ethicists. Fostering strong partnerships between neuroscientists and ethicists that operate and collaborate within this evolving framework will maximize the translation of NRM discoveries on the brain into cures that are safe and address the needs of science and society.
