Overview

In vitro study demonstrates improved Schwann cell activity and reduced fibrosis using a conductive hydrogel conduit, indicating strong potential for peripheral nerve repair.

Key Points

To develop a multifunctional conductive hydrogel-composite nerve conduit with anti-inflammatory, anti-scarring, and electrically active properties to support peripheral nerve regeneration.
Fabricated an electrospun silk fibroin/polycaprolactone conduit loaded with ursolic acid for structural support, sustained drug release, and slow degradation.
Synthesized an injectable silk fibroin/hyaluronic acid hydrogel incorporated with polydopamine-modified polypyrrole nanoparticles to establish an electrically conductive 3D matrix.
Characterized conduit physicochemical properties and evaluated in vitro cytocompatibility with Schwann cells, fibroblast inhibition, macrophage polarization, and electrical stimulation responses.
Polydopamine modification prevented nanoparticle aggregation, establishing a uniform conductive network that significantly improved hydrogel electrical conductivity.
In vitro assessments confirmed high cytocompatibility with Schwann cells and elevated cellular activity following electrical stimulation.
The composite conduit effectively suppressed fibroblast proliferation and collagen secretion while regulating macrophage polarization under inflammatory conditions.
