The scientific, ethical, and policy issues raised by research involving the engraftment of human neural stem cells into the brains of nonhuman primates are explored by an interdisciplinary working group in this Policy Forum. The authors consider the possibility that this research might alter the cognitive capacities of recipient great apes and monkeys, with potential significance for their moral status.

The prospect of using genome technologies to modify the human germline has raised profound moral disagreement but also emphasizes the need for wide-ranging discussion and a well-informed policy response. The Hinxton Group brought together scientists, ethicists, policymakers, and journal editors for an international, interdisciplinary meeting on this subject. This consensus statement formulated by the group calls for support of genome editing research and the development of a scientific roadmap for safety and efficacy; recognizes the ethical challenges involved in clinical reproductive (...) applications of genome editing but, importantly, rejects the idea that human reproductive germline modification is necessarily morally unacceptable; and highlights the importance of meaningful engagement in discussions of genome editing and the development of regulation and oversight mechanisms to govern future uses of such technologies.
