| Outline of Final Research Achievements |
Mesenchymal stem cells (MSCs) retain the ability to self-renew and differentiate into mesenchymal cells. Therefore, MSCs are strong candidates for use in regenerative medicine and cell therapy. Bone marrow-derived MSCs migrated to various tissues including periodontal tissue by chemotaxis, which plays important roles in anti-inflammatory response and tissue repair. We demonstrated that stimulation of inflammatory cytokines, IL-1β, IL-6 and TNF-α, to increase the production and secretion of SDF-1 and MCP-1 in periodontal ligament-derived MSC-like cells. Interestingly, these chemokines specifically increased the migration of bone marrow-derived MSCs, but did not increase that of the periodontal ligament-derived MSC-like cells. In summary, our studies suggested that efficient regenerative medicine could be implemented by effective use of distinct MSCs obtained from various tissues.
