Outline of Final Research Achievements

We developed a novel scaffold using our unique in-body-tissue-architecture technology (iBTA) and implanted it into the trachea and esophagus in animal models. In the esophageal regeneration model, Biosheet, which was consisted of collagen, promoted the regeneration of the stratified squamous epithelium and muscular layer of the esophagus.
In the tracheal regeneration model, a tracheal-like tissue including polylactic acid stent was generated and implanted in a tracheal defect. The regeneration of blood vessels, tracheal epithelium, and cartilage were confirmed on the scaffold. Then, we developed “Hybrid-Biotube” which consisted of an engineered cartilage ring derived from autologous costal chondrocytes and connective tissue in a Lewis rat model. The regeneration of tracheal epithelium and cartilage rings was confirmed after orthotopic circumferential transplantation.
To investigate the tissue regeneration process in detail, we will analyze the tissue regeneration.

Academic Significance and Societal Importance of the Research Achievements

先天性の食道狭窄や気管狭窄において、とくに広範な気管狭窄の場合は、致命的でありながら治療法が確立されていない。現行の標準手術では、術後に肉芽等による狭窄を発症し治療経過に難渋する場合が少なくなく、気管や食道を対象とした臓器移植も臨床応用に至っていない。本研究では自己組織を利用した生体組織形成技術にて、移植可能な人工組織を作成でき、移植臓器内で組織再生を促進することが確認された。我々が開発したBiotube、Biosheet、Hybrid-Biotubeは、現行の標準治療や臓器移植医療に替わり、治療困難な先天疾患に対する新規の治療法となり得る可能性が示唆された。
