Diamond, Nicholas J.2013-02-122013-02-122013-02-12https://hdl.handle.net/11299/144224In this article, I first contextualize the origins of disagreement over the nature and extent of human embryonic stem cell (hESC) research regulation. By analyzing two key pieces of hESC legislation as considered in two landmark court decisions—one from the United States and one from the European Union—I argue that current stem cell policies are deeply flawed. After surfacing the flaws of these policies, I examine novel challenges for policymakers posed by the newest advancement in stem cell science, induced pluripotent stem cells. In view of these novel challenges, I contend that current policies, which are hESC-focused and deeply flawed, will require substantial revision so as to not unnecessarily encumber the ever-growing therapeutic promise of stem cell research.en-USstem cellsstem cell legislationpluripotent stem cellshESChESC legislationhuman embryonic stem cell research regulationhESC research regulationstem cell policyhESC policyhuman embryonic stem cell research policyBrustle v GreenpeaceSherley v.
