(A) Degree of methacrylation (DM) of GelMA with varying amount of methacrylic anhydride added to the reaction. (Inset in B) Polymer content of DN hydrogels with varying DM of GelMA. Effect of DM of GelMA on (B) compressive modulus, (C) failure strain, and (D) failure stress of DN hydrogels. Every crosslinking time was 120 seconds. 0.5% GGMA hydrogels and 20% GelMA(each DM) solutions were used for (A)–(E). (*) indicates significant difference (P < 0.05).
