Meta AnalysisThe effect of stem cells in bridging peripheral nerve defects: a meta-analysis.
OBJECT.: For decades the gold standard for reconstructing a large peripheral nerve defect has been, and remains, the nerve autograft. Alternatives to the nerve autograft include biological conduits and vessels. Adding stem cells in the lumen of a nerve conduit has been the subject of multiple studies. The purpose of the present meta-analysis was to summarize animal experimental studies on the effect of stem cells as a luminal additive when reconstructing a peripheral nerve defect with a nerve graft. ⋯ The present report systematically analyzed the different studies that used stem cells as a luminal additive when bridging a large peripheral nerve defect. All 3 different stem cell groups showed a beneficial effect when used in the reconstruction compared with control groups in which stem cells were not used.
