Physicomechanical properties of decellularized ECM sheets. (A) The extracted ECM was fabricated into porous sheets. (B) The ECM sheets (13-mm diameter and 1-mm thickness) possessed a highly porous microstructure with a high degree of interconnectivity. Scale bar represents 50 μm. (C) Pore size distribution measured by a porosimeter. (D) Representative stress–strain curves of ECM sheets under tensile loading. Each line curve means each sample (n=5).
