Outline of Final Research Achievements

In this study, we aimed to develop colloidal wound dressing with tissue adhesive properties which promote tissue regeneration. This colloid can be delivered by dry spraying and adhere to wound area to protect from external stimuli. Moreover, this particle can interact with various cells and control cellular responses. By understanding the mechanism on tissue regeneration, an innovative wound dressing can be developed.

Academic Significance and Societal Importance of the Research Achievements

本研究では、従来の創傷被覆材のように単純に外部刺激から保護するだけではなく、疎水化微粒子型被覆材がナノバイオ界面で生体組織に積極的に相互作用することで、接着性・止血作用・多細胞シグナリング・血管新生・再上皮化などの生体応答を制御し、組織治癒を促進する点が特徴的である。本材料は、ESD後の創傷治癒のみならず、熱傷や褥瘡、糖尿病性潰瘍などの皮膚欠損の治療や、消化管穿孔の閉鎖、消化管潰瘍への適用、虚血性疾患治療など様々な応用展開が可能であり、国内の医療器機産業の発展に寄与すると考える。
