Live and Dead stained cells in coaxially printed scaffolds irradiated for 12 s at 12mW/cm². NSC-34-laded collagen was extruded as the shell component and myoblast-laden GelMA was extruded as the core component of the bioprinted strands. Two ratios were used for extrusion, 95% core (5% GelMA)/5% shell (2.5 mg/mL methacrylated collagen) (A,C,E) and 90% core (5% GelMA)/10% shell (2.5 mg/mL methacrylated collagen) (B,D,F) at days 7 (A,B), 14 (C,D), and 21 (E,F). Scale bars represent 100 µm.
