Core Tip

Core tip: Outcomes following peripheral nerve injury remain poor. Stem cells may increase Schwann cell numbers and longevity, prolonging their ability to support regeneration. At the level of the cell body, they may have the ability to rescue populations of neurons destined for apoptosis. They may also be used in non-physiologic ways in order to protect muscle targets from the detrimental effects of denervation. Aside from stem cell type, consideration must be given to differentiation status, scaffolding support and the mechanism of delivery. This article reviews current opinion on the strategies of stem cell-based therapy for the augmentation of peripheral nerve regeneration.
