| Outline of Final Research Achievements |
t was reported that fibroblast cell can differentiate into myofibroblast cell via osetoblast cell in the presence of elaschin peptide. Thus, three mixtures of DNA/protamine complex with salmon-derived water-insoluble elaschin, water-soluble elastin and eraschin peptide were prepared. These pastes were implanted into rat cranial defect for three months. It was found that the DNA/protamine complex with elaschin peptide formed new bone faster than the others. Moreover, real-time PCR indicated that elaschin peptide can facilitate the development of αーSMA and MMP-2. Therefore, elaschin peptide will be useful materials for repair of bone defects.
