Outline of Final Research Achievements

In the first half of the research period, we continued autologous animal implantation experiment of in vivo tissue-engineered vascular graft "Biotube" that can be created safely, easily and at low cost. For expanding the indication, development of xenogeneic / allogeneic tissue application was started in the second year of research period. First, we confirmed that physical properties of the graft can be controlled using chemical treatments such as crosslinking and dehydration. In addition, decellularization treatment was also introduced without problems in terms of DNA quantification and physical characteristics of the tissue after treatment. Subsequently, xenogeneic and allogeneic animal transplantation experiments were actually started. The results were good in the pilot study, and as in the case of autologous biotubes, rapid and good organization and strength retention in the systemic circulation environment could be confirmed in short-term.

Academic Significance and Societal Importance of the Research Achievements

自家結合組織代用血管が安定して機能することが再確認された。またハイリスク患者における代用血管の物理特性を化学処理で制御できる可能性が示唆された。また、脱細胞化処理により、健康な個体で作成された良好な組織を今後同種・異種へ移植できる可能性が示された。臨床応用の際に適応されると想定される、ハイリスク患者・高齢者・未熟児など組織再生能力が低下した患者への応用への選択肢の一つとして、健常な個体由来の他家バイオチューブの応用も、より実現性の高い選択肢として可能であると示唆された。今後研究を継続し、まずは同種移植の臨床応用に向けて、免疫学的な検討・長期における安全性の評価を行う予定である。
