"In August, Japan's bioethics panel backed producing embryos from sperm and eggs derived from stem cells, in anticipation of formal approval. The approach is not yet feasible with human cells - but these embryos could eventually be studied for up to 14 days in the laboratory. The research could advance understanding of fertilization, improve assisted reproduction and support genetic research."
"T.S. declares the following positions: member, Asian Bioethics Network, established under the Bioethics Advisory Committee (BAC), Singapore; deputy editor, JME Practical Bioethics; committee member, Third-party Committees on Cell Manufacturing Contract from Commercial Institutions (The CiRA Foundation, Kyoto University); committee member, Institutional Ethics Committee, Center for iPS Cell Research and Application, Kyoto University; committee member, Institutional Review Committee for the Use of iPS Cell Stock (The CiRA Foundation, Kyoto University). All of these positions are unpaid and unrelated to the content of this publication."
Japan's bioethics panel backed producing embryos from sperm and eggs derived from stem cells in anticipation of formal approval. The method is not yet feasible with human cells, though analogous techniques may progress. Resulting embryos could be maintained in the laboratory for up to 14 days for study. Research using these embryos could improve understanding of fertilization processes, enhance assisted reproduction technologies, and support genetic research. Ethical oversight and conflict-of-interest disclosures accompany the decision, with named experts listing unpaid roles connected to bioethics and stem-cell committees. Potential medical and scientific benefits are balanced against ongoing ethical considerations and regulatory review.
