Wnt 3a-Modified Scaffolds Improve Nerve Regeneration by Boosting Schwann Cell Function.

A pivotal approach in engineering artificial peripheral nerve sheaths encompasses the augmentation of the regenerative microenvironment via the manipulation of Schwann cells (SCs). Our investigation employed single-cell sequencing analysis to elucidate the potential functions of Schwann cells and the Wnt pathway in facilitating peripheral nerve regeneration. studies showed that activating the Wnt signaling pathway promotes the transition to repair SCs, boosting their growth, movement, and immune functions.

Exogenous Mitochondrial Transplantation Facilitates the Recovery of Autologous Nerve Grafting in Repairing Nerve Defects.

Autologous nerve transplantation (ANT) remains the gold standard for treating nerve defects. However, its efficacy in nerve repair still requires improvement. Mitochondrial dysfunction resulting from nerve injury may be a significant factor limiting nerve function restoration.

Biological characteristics of tissue engineered-nerve grafts enhancing peripheral nerve regeneration.

Background: A favorable regenerative microenvironment is essential for peripheral nerve regeneration. Neural tissue-specific extracellular matrix (ECM) is a natural material that helps direct cell behavior and promote axon regeneration. Both bone marrow-derived mesenchymal stem cells (BMSCs) and adipose-derived mesenchymal stem cells (ADSCs) transplantation are effective in repairing peripheral nerve injury (PNI).
