Peripheral-Nerve Regeneration
Regrow damaged nerves and reconnect feeling and movement
The goal is to regrow severed and damaged peripheral nerves — and reconnect them to muscle and skin — so that lost feeling and movement return, faster and more completely than the body manages alone.
The peripheral nerves are the body’s wiring, carrying movement out and sensation back. Unlike the brain and spinal cord, they can regrow — but slowly (about a millimeter a day), incompletely, and often not far enough, so serious injuries leave lasting numbness, weakness, and pain. Because the natural ability exists, amplifying and guiding it is achievable — making peripheral-nerve regeneration the flagship of the nerves, and a model for the harder central-nervous-system goals.
We are building the capability to regrow nerves to their targets and restore what they carry: guiding severed nerves to regenerate along the right path, speeding and extending that growth, rebuilding the myelin that lets signals travel, and reconnecting nerves to the muscles and sensors they serve.
Guiding nerves to regrow and reconnect
Nerve guidance conduits Advancing — some clinical
Engineered guidance conduits bridge a nerve gap and direct regrowth along the correct path; several are in clinical use for nerve repair.
Accelerating regrowth Frontier
Growth signals aim to speed the slow natural pace of nerve regeneration and extend how far nerves will regrow.
Rebuilding myelin Frontier
Regrowing the myelin insulation around nerve fibers restores the speed and fidelity of signals.
Reconnecting to targets Frontier
Regrown nerves must reconnect to the right muscles and sensory endings to actually restore movement and feeling.

The technologies: nerve guidance conduits and engineered grafts; growth factors that drive and direct regrowth; remyelination therapies; and the regeneration biology that explains why peripheral nerves can regrow and how to push it further.
Conduits in clinical use Clinical
Nerve guidance conduits are in clinical use to bridge nerve gaps and direct regrowth, improving on unaided repair.
Natural regrowth is real Demonstrated
Peripheral nerves demonstrably regenerate — the biological foundation this capability builds on.
Remyelination research Frontier
Therapies to regrow myelin and restore signal speed are advancing in the lab.
Faster, farther regrowth Frontier
Growth-signal approaches to speed and extend regeneration are advancing in research.
The honest challenges: regrowth is slow, and over long distances muscles can waste before the nerve arrives — speed and reach are real limits. Reconnecting precisely to the right targets is hard. Remyelination and full sensory restoration in people are largely frontier. Guidance conduits are clinical for bridging gaps; faster, complete functional restoration is advancing-to-frontier, labeled honestly.
The future, fully built
A person with nerve damage — numbness, weakness, or pain — has their nerves regrown and reconnected: guided back to their targets, myelin rebuilt, feeling and movement restored. Nerve function becomes something we restore, not damage people live around.
