Based on these findings, pharmaceutical compositions for the prevention and/or treatment of inflammatory bowel diseases, which comprise the HMGB1 fragment peptide having the specific amino acid sequence are provided.

Abstract: The inventors of the present invention searched for a substance that is effective in treating a cartilage disorder, and as a result, found that, in an animal model of joint cartilage deficiency, an HMGB1 fragment peptide having a specific amino acid sequence exhibits the effect of reproducing a healthy cartilage tissue including a hyaline cartilage. Based on this finding, the present invention provides a pharmaceutical composition that contains the specific HMGB1 fragment peptide and that is for preventing and/or treating a cartilage disorder.

Abstract: Biologically low invasive vessels are filled with biological factors that have the activity of mobilizing specific functional cells in the body. The vessels are indwelled in the body. After specific functional cells are mobilized into the vessels, the vessels are removed from the body to collect functional cell populations mobilized to the vessels. Alternatively, the cells are directly collected from the vessels indwelled in the body.

Abstract: It was revealed that the intravenous administration of HMGB-1 and S100A8 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 mice intravenously administered with HMGB-1 as compared to the control. The post-cerebral infarction survival rate was increased in the intravenous HMGB-1 administration group. The involvement 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.

Abstract: A peptide which can be utilized as an active ingredient of a composition for use in stimulation of migration of PDGFR?-positive cells, a composition for use in recruitment of bone marrow mesenchymal stem cells from bone marrow to peripheral blood, a composition for use in regeneration of tissues, or a composition for use in stimulation of migration of bone marrow-derived stromal cells is provided.

Abstract: The inventors discovered that ectodermal mesenchymal stem cells circulating in peripheral blood that are induced by necrotic tissue damage contribute to the regeneration of damaged tissue. On the basis of this discovery, provided are ectodermal mesenchymal stem cells, a method for producing the same, and a screening method for a substance having pluripotent stem cell inductive activity, the screening method using cells induced by necrotic tissue damage in peripheral blood as an index.

Abstract: (Objective) An objective of the present invention is to provide therapeutic agents that, in association with stimulation of PDGFR?-positive cells such as bone marrow mesenchymal stem cells, promote their mobilization into blood and accumulation in a damaged tissue, and induce tissue regeneration in a living body. (Means for solution) Multiple peptides were synthesized, and the migration-promoting activity of each peptide was evaluated. As a result, the present inventors successfully identified multiple peptides that have migration-promoting activity on a PDGFR?-positive bone marrow mesenchymal stem cell line (MSC-1). Further, the present inventors confirmed that the identified peptides also have migration-promoting activity on skin fibroblasts, which are PDGFR?-positive cells.
