Structure of 3D-printed Gel/SA/dECM scaffolds. 5G3S1d and 6G3S1d were printed with the temperature of 20° and pressure of 0.20 Mpa, while 7G2S1d was printed with the temperature of 24° and pressure of 0.24 Mpa. (A) Macrostructure of the scaffolds before and after crosslinking by 3% CaCl₂ and EDC/NHS. Scale bar: 5 mm. (B) Microstructure of crosslinked scaffolds observed by scanning electron microscope. The left images (scale bar: 100 μm) were enlarged and shown on the right (scale bar: 100 μm). (C) Distribution of small pore size in the scaffolds.
