Optimization for differentially cross‐linked porous ChCo scaffolds (A) The colour changes of the porous scaffolds according to different genipin cross‐linking. (B) The surface structure of differentially cross‐linked scaffolds identified by SEM; the red arrows indicated the fissures of the pore wall. (C‐F) The swelling ratio, cross‐linking degree, tensile strength and degradation rate alterations of differentially cross‐linked scaffolds. The representative statistical results were performed using one‐way ANOVA test and shown as means ± SEM from 3 independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001
