제목 Tissue engineered spinal cord using neuronal cells seeded polymeric scaffold
초록 Brain-derived neurotrophic factor (BDNF) appears to enhance the regrowth of ascending sensory axon across spinal cord gap in adult rats. We postulated that resected segment of the spinal cord could be regenerated in adult rat gap implanting neuronal cells and BDNF associated with polymeric porous scaffold. Fabrication of nerve guidance channeled PLGA scaffold was performed by ice-particle leaching method. Neuronal cells such as that SC and OEC isolated from female Fischer rats were suspended with BDNF. Fischer rats with the various gaps (1~5 mm) created through the spinal cord transection were implanted by the PLGA/cells/BDNF. For histological evaluation, we were stained by H&E, S-100, NF, NSE. Histological examination confirmed exhibited the regenerated tissue with bundles than appeared to do axons for rats. In addition, NF-positive areas were observed in the regenerated tissue of regeneration group. Acknowledgement: This work was supported by SCRC (SC3100) from KMOST.
