Bioethics is an interdisciplinary field of research dealing with âethical issuesâ that cannot be judged by traditional values, which arise as the advancement of science and technology. Ethical issues, such as whether human embryos may be created from human stem cell-derived artificial gametes, conditions in which we need moral considerations for human brain organoids, etc., which the society would face in the future have to be discussed in advance. Furthermore, bioethics considers how rules and procedures should be implemented to conduct research appropriately. For the advancement of science and technology and to be trusted by society, it is essential to study these ethical issues and hold open discussions in society. Therefore, in our laboratory we are engaging in the following activities:
1. Theoretical research: We will extract and organize issues to be considered from an ethical point of
view, such as literature research on the moral status of human embryoids and human brain organoids, and
deepen philosophical discussions.
2. Empirical research: Based on the findings of the theoretical research, we are conducting surveys on the attitudes of the general public and scientists toward human stem cell-derived artificial gametes, genome editing of human embryos, and so forth.
3. Policy proposals: We will provide points of discussion and issues extracted from the theoretical research as well as the results of empirical research to the Cabinet Office and the Ministry of Education, Culture, Sports, Science, and Technology to implement regulations, and aim to reflect the opinion of the people and researchers in further discussion.
4. Outreach activities: We will try to initiate social discussions by disseminating the research results widely across society. We will deploy these research works by collaborating with other scientists at our institution, and aim to build a new research model that combines humanities and science.
