Research Abstract |
To improve outcome of global cerebral ischemic pathophysiology, the effect of neurospheres, which was formed from side population cells in dental pulp tissue, were examined. Cerebral expressions of cytokines and BDNF, brain derived neuronal factor, were also examined as expected mechanisms of neuroprotection associated with neurosphere treatment. Post-ischemic intravenous implantation of neurosphere-derived cells after 3 hours of reperfusion improved histological outcome. However, mRNA expressions either of cytokines or BDNF were not significantly different among groups. It was surmised that outcome improvement from neurosphere treatment was caused by mechanisms other than cerebral inflammation process or BDNF overexpression.
