| Outline of Final Research Achievements |
The peripheral nerve injury made the significant up-regulation of BMP7/Smad signaling in the axon-Schwann cell units at the distal to the injured site. in vitro study demonstrated that cell viability of Schwann Cells(SCs) was significantly increased by administration of BMP7. Also by PTH(1-34) administration, electrophysiological studies showed the advantage of improvement of MCV after peripheral nerve injury. Furthermore, in vitro study, the Expression of BMP7 in SCs was significantly increased by administration of PTH(1-34).From these results, re-expressed BMP7/Smad signal can indirectly function in axonal regeneration as a neurotrophic growth factor for SCs, and suggested that PTH(1-34) is not only acting on bone metabolism, and is involved in peripheral nerve regeneration through SCs.
