Background:

  • Nerve grafts are crucial for clinical nerve repair.
  • Understanding nerve-extracellular matrix (ECM) interactions is key to improving nerve regeneration.
  • Existing decellularization protocols may compromise native nerve structure.

Purpose of the Study:

  • To engineer an acellular nerve graft for clinical use and research.
  • To investigate the effects of various detergents on peripheral nerve tissue.
  • To develop an optimized decellularization protocol that preserves nerve ECM structure.

Main Methods:

  • Systematic examination of detergent effects on peripheral nerve tissue.
  • Histochemistry and Western blot analysis to assess cellular and ECM components.

    • Main Results:

    • Identified specific detergents (Triton X-200, sulfobetaine-16, sulfobetaine-10) that effectively remove cells.
    • Demonstrated preservation of peripheral nerve morphology and protein composition.
    • Established an improved decellularization protocol superior to current methods in preserving native nerve structure.

    Conclusions:

    • An optimized chemical decellularization protocol was developed for nerve grafts.
    • The protocol effectively removes cells while preserving the nerve's extracellular matrix.
    • This engineered acellular nerve graft serves as a valuable tool for studying nerve regeneration and clinical repair.
