In this study, the authors examined the use of blood-derived CD133+<\/jats:sup> cells in promoting the repair of peripheral nerve defects.<\/jats:p><\/jats:sec>\n\nMethods<\/jats:title>\nThe authors transplanted phosphate-buffered saline (control), mononuclear cells, or CD133+<\/jats:sup> cells embedded in atelocollagen gel into a silicone tube that was used to bridge a 15-mm defect in the sciatic nerve of athymic rats (12 animals in each group). At 8 weeks postsurgery, molecular, histological, and functional evaluations were performed in regenerated tissues.<\/jats:p><\/jats:sec>\n\nResults<\/jats:title>\nThe authors found that sciatic nerves in which a defect had been made were structurally and functionally regenerated within 8 weeks after CD133+<\/jats:sup> cell transplantation. From macroscopic evaluation, massive nervelike tissues were confirmed only in rats with CD133+<\/jats:sup> cell transplantation compared with the other groups. Morphological regeneration in the samples after CD133+<\/jats:sup> cell transplantation, as assessed using toluidine blue staining, was enhanced significantly in terms of the number of myelinated fibers, axon diameter, myelin thickness, and percentage of neural tissue. Compound muscle action potentials were observed only in CD133+<\/jats:sup> cell\u2013treated rats. Furthermore, it was demonstrated that the transplanted CD133+<\/jats:sup> cells differentiated into Schwann cells by 8 weeks after transplantation.<\/jats:p><\/jats:sec>\n\nConclusions<\/jats:title>\nThe results show that CD133+<\/jats:sup> cells have potential for enhancement of histological and functional recovery from peripheral nerve injury. This attractive cell source could be purified easily from peripheral blood and could be a feasible autologous candidate for peripheral nerve injuries in the clinical setting.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2008.3.17571","type":"journal-article","created":{"date-parts":[[2008,11,14]],"date-time":"2008-11-14T15:18:18Z","timestamp":1226675898000},"page":"758-767","source":"Crossref","is-referenced-by-count":22,"title":["Regeneration
