(a) Stress-strain curves of GelMA (10 wt%) and scaffold-reinforced GelMA hydrogels (scaffold-GelMA hydrogel) obtained from uniaxial compression. The microfabricated scaffold was made from 100 wt% PEGDA. (b) Ultimate stress, (c) ultimate strain and (d) elastic moduli (E) values of GelMA hydrogel and scaffold-GelMA hydrogel. The concentration of GelMA was varied from 5 wt% to 10 wt%.(*p<0.05)
