A NOVEL TECHNIQUE FOR NERVE DECELLULARISATION: HISTOLOGICAL AND IN VIVO PRELIMINARY ENCOURAGING STUDIES

For unrepairable nerve defects, to date autogenous nerves are considered the golden standard, but donor site morbidity, limited availability and operation time prolongation are relevant problem. Acellular nerves from cadaveric donor, introduced since more than one decade ago, represent a novel promising alternative to bridge unrepairable nerve gaps.Aim of this study is to provide a new tool to ameliorate the assistance of the numerous patients suffering from traumatic, oncological and jatrogenic nerve lesions. For this purpose, our project is promoting a progress beyond the state of the art of nerve gaps bridging surgery by developing a new technique to obtain acellular nerve allografts (ANAs).Several methods to examine the effect of detergents on nerve tissue morphology and protein composition have been previously reported. Most of them are too expensive and time consuming. The presented novel decellularization technique is a modification of the Michigan detergent-based organic material removal, to speed...
