Area of Science:

  • Regenerative Medicine
  • Microsurgery
  • Tissue Engineering

Background:

  • Peripheral nerve repair is a significant challenge in restorative medicine, with current methods like autografts offering incomplete functional recovery.
  • Severe nerve lesions often result in partial and unsatisfactory outcomes despite advances in tissue engineering.

Purpose of the Study:

  • To review recent achievements in tissue engineering for peripheral nerve repair.
  • To identify promising research directions for consistent progress in nerve regeneration.

Main Methods:

  • Development of artificial nerve guidance channels (NGCs) using various natural and synthetic polymers.
  • Incorporation of bioactive fillers and creation of porous/nonporous NGCs.
  • Investigation of biomimetic NGCs with chemotactic, topological, and haptotactic signaling.

Main Results:

  • Several NGCs have been developed, with some approved for clinical use.
  • Ongoing research focuses on biomimetic NGCs that provide advanced cellular signaling.
  • The trend is towards NGCs that mimic natural nerve environments for better axon guidance.

Conclusions:

  • Artificial NGCs are crucial for guiding axon regeneration and improving functional recovery after nerve lesions.
  • Biomimetic NGCs represent the future of nerve tissue engineering, offering multi-faceted cellular cues.
  • Continued research into advanced NGC designs is essential for overcoming the limitations of current peripheral nerve repair strategies.
