However, the use of this technique is not without problems, including limited supply, associated donor-site morbidity, and size mismatches with the injured nerve 4. Until recently, an interposition autologous nerve graft has been considered the gold standard for nerve regeneration and has produced the best results for peripheral nerve injury with advanced crushing or defects since the first evidence of autologous nerve grafting in animal studies in 1967 2, 3. However, in long-term defects or severe injury, the regeneration capacity of a nerve is limited 1. Our results support the future clinical application of CNTs for bridging nerve defects as an off-the-shelf material.Īn injured peripheral nerve can regenerate spontaneously or via a microsurgical suture. We confirmed that CNT yarn promotes peripheral nerve regeneration by using it as a scaffold for repairing nerve defects. A 2% CNT density tended to be the most effective for nerve regeneration as measured by both histological axonal regeneration and motor function.
Furthermore, the sciatic nerve functional index (SFI) at 16 weeks showed improvement in gait function. Eight weeks after the surgery, the regenerated axons crossing the CNTs, electromyographical findings, and muscle weight ratio of the lower leg showed recovery of the nerve function by interfacing with cYarn. We bridged a 15 mm rat sciatic nerve defect with five different densities of cYarn. We focused on CNTs fabricated with the carbon nanotube yarns (cYarn) as a possible substrate promoting peripheral nerve regeneration with these properties.
