As the use of human body parts has become increasingly commercialized, a need has arisen for new approaches to regulation that moves beyond the paradigm of altruism. During the course of this discussion, the notion of property has become a key concept. Focusing on practical and conceptual perspectives, the multidisciplinary group of authors, which includes specialists in philosophy, law, sociology, biology and medicine, have come together with practicing lawyers to consider both legal provisions and patterns of regulation in countries across Europe. Identifying divergences between different legal traditions, the authors explore various conceptual models which could be used to improve and to guide policy making. With this twin focus on practical and conceptual perspectives, this volume sets the standard for a detailed and innovative discussion of issues surrounding the regulation of research on human tissue.
