Regulation of cell-based therapies in Europe: current challenges and emerging issues.

Europe is ready to deploy its immense capital of knowledge into the development of effective cell-based therapies and delve into the global race for translating stem cell science into regenerative medicine. But what are the challenges and the emerging issues that lay ahead the realization of Europe's enormous potential in this field? Both researchers and industrial stakeholders tend to impute the slow pace of translation to specific suboptimal features of the regulatory environment in Europe. At the same time, a host of new issues are emerging as testified by a recent public controversy regarding the provision of unproven cell therapy in Italy. We will review this topic and suggest some solutions to foster the responsible development of innovative cell-based therapies in Europe.
