Primary physicochemical and mechanical characterizations of the GelMA/Si-HPMC hydrogels different mass ratio of GelMA (G) and Si-HPMC (Si). A Outward appearance and SEM observation of the hydrogels; B-G Rheological analysis involving the storage modulus (G′) and loss modulus (G′′) under 1 mW/cm² 365 nm light irradiation; H Representative compressive stress–strain curves of the hydrogels; I Compressive strength of the hydrogels; J Swelling curves of the hydrogels; K Mass decay of the hydrogels during immersion in PBS at 37℃. * p < 0.05
