| Research Abstract |
After BMSC trbone marrow stromal cell(BMSC) treatment, locomotor function was significantly improved in BMSC group. Resident microglia and hematogenous macrophage activation were supressed in chronic state after spinal cord injury. Also, allodynia like behavior was supressed in chronic state after spinal cord injury. So, supression microglia and macrophage has possibility to improve the neuropathic pain after spinal cord injury. In this study, most important problem was the low survival rates of transplanted BMSC. Therefore, we decided to also use anti-IL-6 receptor antibody(MR16-1). With this treatment, the survival rates of BMSC were significantly increased and locomotor function was also improved than BMSC treatment only.
