Executive Industry Relevance

This protocol establishes a biologically relevant model for studying peripheral nerve regeneration, supporting target validation in neuromuscular repair strategies. By enabling reinnervation of motor and sensory pathways, it provides a disease-relevant system for mechanistic de-risking of regenerative therapies. The approach aids preclinical evaluation of interventions aimed at restoring functional connectivity after nerve injury.

Implementation Considerations

• Requires expertise in microsurgical techniques and peripheral nerve anatomy.
• Necessitates instrumentation including dissecting microscope, microsutures, and sterile surgical field.
• Demands cross-team standardization of graft harvest, nerve transection, and closure procedures.
• Involves adaptation considerations when translating to other nerve injury models or species.
• Includes practical limitations such as variability in graft take and reinnervation kinetics, as noted in postoperative monitoring requirements.
