title: Perspectives in regeneration and tissue engineering of peripheral nerves.
abstract: Peripheral nerve injury is a common casualty and although peripheral nerve fibers retain a considerable regeneration potential also in the adult, recovery is usually rather poor, especially in case of large nerve defects. The aim of this paper is to address the perspectives in regeneration and tissue engineering after peripheral nerve injury by reviewing the relevant experimental studies in animal models. After a brief overview of the morphological changes related to peripheral nerve injury and regeneration, the paper will address the evolution of peripheral nerve tissue engineering with special focus on transplantation strategies, from organs and tissues to cells and genes, that can be carried out, particularly in case of severe nerve lesions with substance loss. Finally, the need for integrated research which goes beyond therapeutic strategies based on single approaches is emphasized, and the importance of bringing together the various complimentary disciplines which can contribute to the definition of effective new strategies for regenerating the injured peripheral nerve is outlined.
