| Outline of Final Research Achievements |
In previous study, we have revealed that the locomotor function of rats are improved by injection of basic fibroblast growth factor (FGF2) into the spinal cord, immediately after the complete transection, via stimulating the proliferation of resident fibroblast-like cells {FGF2-induced fibroblast-like (FIF) cells]. On the other hand, transplantation of dental pulp cells (DPCs) also improved the locomoter functions: DPCs are derived from mesenchymal stem cells as FIF cells.
In this study, we investigated the possibility whether both treatments would provide additive and/or synergistic effects on the function recovery. The effect of the DPCs on the locomoter function was improved when the cells were treated with FGF2 before transplantation. Further investigations revealed that both FGF2 injection and DPCs transplantation are comparable and highly effective for locomoter function recovery: however, additive and/or synergistic effects were not observed in the combinations.
