Mass ratio (GelMA/GGMA), polymer content, compressive modulus, failure strain, and failure stress of DN hydrogels with varying concentration of either component: (A) varying concentration of GGMA hydrogels + 20% GelMA solution, and (B) 0.5% GGMA hydrogels + varying concentration of GelMA solution. GelMA (DM: 32.3%) was used for (A)–(B). (*) indicates significant difference (P < 0.05).
