Abstract

Peripheral nerve regeneration (PNR) represents a substantial challenge in the medical field, primarily due to the limited regenerative capacity of the peripheral nerve system (PNS). Current research efforts are focused on developing advanced medical polymer materials to enhance nerve recovery. Despite significant progress, several critical issues remain unresolved, including biocompatibility, stability, mechanical strength, controlled degradation rates, and sustained release of therapeutic agents. This study examines the utilization of hyaluronic acid hydrogels, doped with mecobalamin (MeCbl) and conductive poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS), in combination with exogenous electrical stimulation (ES) for PNR of rats. The strategy utilizes the MeCbl hydrogel to create a regenerative microenvironment and provide nutritional support for nerve cells, while PEDOT:PSS facilitates enhanced electrical signal conduction. ES has been shown to promote PNR and functional recovery, thereby demonstrating considerable potential. This study aims to comprehensively analyze the synergistic effects and potential value of this combined therapeutic approach, providing novel insights and pathways for the effective PNR.
