| Outline of Final Research Achievements |
Phamacological activities of platelet rich plasma: PRP and freeze-dried: fd PRP were evaluated. ELIZA tests of PDGF, FGF, and EGF showed similar concentrations in fresh PRP and 52 weeks saved PRP. Lumbar posterolateral fusion models were allocated to the sham, autologous graft, artificial bone-alone, artificial bone+fdRPR, artificial bone+PRP. Histological examination revealed similar good results in artificial bone+fdPRP and artificial bone+PRP.

| Academic Significance and Societal Importance of the Research Achievements |
Platelet Rich Plasma: PRPと凍結乾燥したfreeze-dried:fd PRP（52週間保存後）の薬理活性はほぼ同程度だった。骨形成機能もBMPと同程度の効果があった。骨欠損のある患者で凍結乾燥したPRPが使用できれば臨床の現場で非常に有効である。今後は3-5年の長期保存の効果を明らかにするとともに、凍結乾燥PRPバンクの構築が実用化に向けて重要であると考える。
