Figure 2. Mechanical, porosity and degradation properties of GelMA hydrogels.

Figure 2

A) pre modulus of GelMA-hydrogels varies with different macromer concentration and degree of methacryloyl modification. B) Pore size analysis of GelMA hydrogels. C) Degradation of GelMA hydrogels with various macromer concentration and methacryloyl modification degree in the presence of collagenase. D) Cross-Sectional scanning electron microscopy images of 5% HM-GelMA, 7% MM-GelMA, and 10% MM-GelMA hydrogels reveal different porosity. Data depict Mean ± Standard deviation. *p<0.05
