Outline of Final Research Achievements

Using the physical property measurement system completed in FY2020, we measured various mechanical parameters of biogenic materials. First, we applied chemical treatments such as ethanol and glutaraldehyde to porcine pericardium purchased from a supplier for a short period of time and compared the physical properties with those of untreated raw pericardium. Specifically, the following physical properties were measured: 1) burst pressure, 2) thread hooking strength using vascular sutures, 3) rupture strength, 4) elastic modulus, 5) tensile strength of the membrane cut into strips, 6) elasticity of the membrane, 7) elasticity of the membrane, 8) elasticity of the membrane, and 9) elasticity of the membrane in the presence of glutaraldehyde. We have completed a system that can measure parameters such as maximum length at break in accordance with ISO standards. We plan to apply this system to optimize the physical properties of various biomaterials by evaluating their physical properties.

Academic Significance and Societal Importance of the Research Achievements

湿潤環境で生体組織の物理特性評価をISO基準に準拠して行う事の出来るシステムを開発した。再現性が高いシステムによる標準化されたシステムで、現在様々な施設で盛んに行われている再生医療による生体代用代用組織の物理特性を比較することにより、更に理想的な移植用組織開発が行える可能性が示唆された。
