(A) Stress-strain curves for SN and DN hydrogels under uniaxial compression. (B) Polymer content, (C) compressive modulus, (D) failure strain, and (E) failure stress of SN and DN hydrogels. (†) indicates the stress under which the majority of GelMA SN gels started to break, and the strain at that stress. Every crosslinking time was 120 seconds, and GelMA (DM: 32.3%) was used for (A)–(E). (*) indicates significant difference (P < 0.05).
