The explosion of interest in stem cell research raises a raft of controversial policy questions. When should human embryos be used to create stem cells? Should cloning be outlawed? Should egg and tissue donors be paid? Should we allow stem cells to be patented? Is the government entitled to a portion of the revenue from stem cell technology created with public funds? How should the FDA and the courts balance access to revolutionary treatments with protection of the public against unknown risks? In this book, Russell Korobkin and Stephen Munzer provide the first thorough discussion and analysis of these and other unsettled legal and policy issues surrounding stem cell science. Their clear and concise description of complex problems coupled with logical and well-balanced policy conclusions makes this volume essential reading for scholars and general readers concerned with the success of stem cell research and the future of regenerative medicine.
