Fig 3. Mechanical properties of fish GelMA hydrogels with various degrees of methacrylation and gel percentages.

Fig 3

(A) Compressive modulus for 5%, 10% and 15% (w/v) fish GelMA at low, medium and high degree of methacrylation, with the exception of low degree, 5% and 10% (w/v) GelMA which formed gels too weak to be handled for testing. (B) Representative stress-strain curve of a 15% (w/v) GelMA according to degree of methacrylation. (C) Comparison of fish and porcine GelMA hydrogels with a high degree of methacrylation. (D) Representative curve of 15% (w/v) GelMA for fish and porcine GelMA comparison. Conditions of 10% and 15% (w/v) GelMA were significantly different (*p<0.05, **p<0.01, ***p<0.001). Error bars represent SDs of measurements performed on 3 samples.
