The Nuffield Council on Bioethics in the UK recommends setting guidelines for stem cell research that mimics aspects of embryonic development. They suggest not using these models to start pregnancies or making them capable of feeling pain or awareness. Current models are not advanced enough for these outcomes, but researchers are continuously improving them. The field is moving quickly, with research teams worldwide racing to create more complex models. Governance structures are not yet updated to regulate this fast-paced field, highlighting the need for clear guidelines and red lines in stem cell research.
