Effect of genipin concentration on GDH cross-linking rule and stability. (A) The stress–strain curves of the GDH hydrogels with different genipin concentrations; (B,C) the maximum strain and maximum stress of the GDH hydrogels with different genipin concentrations; (D) the elastic modulus of the GDH hydrogels with different genipin concentrations; (E) the stability of GDH reflected by the time of complete degradation in vitro. Data represented mean ± SD (n = 5); *p < 0.05, vs. 0% group; # p < 0.05, vs. 0.1% group; & p < 0.05, vs. 0.02% group.
