Fig. 2. Mechanical characterization of MeTro/GelMA and MeTro/GelMA-AMP composite hydrogels.

Fig. 2.

(a) Elastic modulus, (b) compressive modulus, (c) extensibility, (d) energy loss, and (e) ultimate stress of hydrogels produced by using 15% and 20% (w/v) total polymer concentration, at varying ratios of MeTro to GelMA. (f) Elastic and compressive modulus of MeTro/GelMA and MeTro/GelMA-AMP (containing 0.1% (w/v) AMP) hydrogels produced by using 15% (w/v) total polymer concentration; the results show no significant difference in mechanical properties of hydrogels with and without AMP. Data is represented as mean ± SD (*p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001 and n ≥ 5).
