Abstract EN
Background.
The purpose of this experiment was to develop a peripheral nerve interface using cultured myoblasts within a scaffold to provide a biologically stable interface while providing signal amplification for neuroprosthetic control and preventing neuroma formation.
Methods.
A Regenerative Peripheral Nerve Interface (RPNI) composed of a scaffold and cultured myoblasts was implanted on the end of a divided peroneal nerve in rats ( n = 25 ).
The scaffold material consisted of either silicone mesh, acellular muscle, or acellular muscle with chemically polymerized poly(3,4-ethylenedioxythiophene) conductive polymer.
Average implantation time was 93 days.
Electrophysiological tests were performed at endpoint to determine RPNI viability and ability to transduce neural signals.
Tissue samples were examined using both light microscopy and immunohistochemistry.
Results.
All implanted RPNIs, regardless of scaffold type, remained viable and displayed robust vascularity.
Electromyographic activity and stimulated compound muscle action potentials were successfully recorded from all RPNIs.
Physiologic efferent motor action potentials were detected from RPNIs in response to sensory foot stimulation.
Histology and transmission electron microscopy revealed mature muscle fibers, axonal regeneration without neuroma formation, neovascularization, and synaptogenesis.
Desmin staining confirmed the preservation and maturation of myoblasts within the RPNIs.
Conclusions.
RPNI demonstrates significant myoblast maturation, innervation, and vascularization without neuroma formation.
