 The group has requested that all authors of embryonic stem cell papers submit a statement of authenticity of any new cell-lines and that the source of stem cells be clearly specified.On the ethical issues surrounding embryonic stem cell research, the group has additionally recommended that an international database be created, containing guidelines for ethical practice, research protocols, consent forms, and the information provided to donors.However, the potential for an international consensus on these matters seems remote given the complexity and diversity of regulatory frameworks in this controversial area of science, both within nations and between nations.
