Hopes are high that stem cell (SC) research will lead to treatments and cures for some of the most serious diseases affecting humankind today The book considers the regulatory governance of stem cell research, setting out a readily understandable account of the science and the challenges it poses for regulators as the research is increasingly being clinically applied. It provides a critical account of those elements of a regulatory system which will be required for any jurisdiction aiming to facilitate innovative and productive SC research while maintaining appropriate ethical and legal controls. The book addresses the specific failings in the current regulatory approach to SC research in the UK and goes on to look at the regulatory approaches in the US.
