(a) Schematic of the 3D cell printing process using the dECM-MA-based bioink and UV crosslinking process. (b) Schematics describing the alignment and leaching of PVA fibrils during the processes. (c) Rheological properties (G’ and complex viscosity (η*)) of dECM-MA-based bioinks (3 wt%) mixed with three different weight fractions of PVA (5, 10, and 15 wt%) (n = 5, *P < 0.05). (d) Optical, SEM, and live (green)/dead (red) images of the structures (8 × 8 × 0.5 mm3) printed using the bioinks at 1 d. (e) Initial cell viability and (f) cell loss of the three different bioinks at 1 d after the removal of the PVA components (n = 9, *P < 0.05).
