Research Abstract

Nestin is a class VI intermediate filament expressed in NPCs. To study whether neurons and glia proliferate in situ or migrate from specific regions harboring neural progenitor cells, we applied L5 spinal nerve transection to nestin-promoter GFPtransgenic mice to narrow the target to neural progenitor cells. It was suggested that proliferation of neural progenitor cells and their differentiation into neurons and astrocytes occur in the dorsal horn in response to peripheral nerve injury and that they may contribute to the maintenance of neuropathic pain at the late phase after peripheral nerve injury.
