Research Overview

The peripheral nervous system can regenerate, but injuries that remove a segment of nerve make functional recovery a genuine challenge. This work tested whether biodegradable poly(lactic acid) conduits combined with human adipose-derived stem cells improve regeneration of the sciatic nerve.

Mice underwent sciatic nerve transection followed by tubulization with a PLA conduit, then received either medium alone or human adipose-derived stem cells inside the conduit. Sensory and motor recovery were assessed by pinprick testing and electroneuromyography, and neuronal survival was measured by retrograde fluorogold tracing — giving both functional and anatomical readouts of repair.
