| Outline of Final Research Achievements |
Distraction osteogenesis (DO) successfully induces large-scale skeletal tissue regeneration, but it involves an undesirably long treatment period. A high-speed DO mouse model (H-DO) failed to generate new bone callus in the distraction gap. In this study, we showed that H-DO induced pro-inflammatory reaction in the gap. Importantly, we found that administration of anti-inflammatory M2 macrophage inducer, monocyte chemoattractant protein-1 (MCP-1) and the secreted ectodomain of sialic acid-binding Ig-like lectin-9 (ED-Siglec-9), restored callus formation in the H-DO- gap.
