ABSTRACTIt was revealed that the intravenous administration of HMGB-1 and S 100A8 promoted the healing of skin ulcer by recruiting bone marrow-derived cells to the site of skin ulcer.Furthermore, when HMGB-1 was intravenously administered to cerebral infarction model mice after creation of cerebral infarction, bone marrow-derived cells expressing nerve cell markers were detected in their brain. A marked cerebral infarct-reducing effect was observed in miceintravenously administered with HMGB-1 as compared to the control. The post-cerebral infarction survival rate was increased in the intravenous HMGB-1 administration group. Theinvolvement of bone marrow pluripotent stem cells in the process of bone fracture healing was assessed using mice, and the result demonstrated that bone marrow-derived cells distant from the damaged site migrated to the bone fracture site to repair the damaged tissue.
