Fabrication of macroporous constructs from degradable NorHACA, non-degradable NorHA, and NorHACA/NorHA mixtures. (a) (top) Fluorescence images of 3D printed macroporous discs. Scale bar: 1 mm. (bottom) Representative maximum projection images of the pores within the discs. Scale bar: 200 μm. (b) Cumulative uronic acid release and compressive modulus (EC) over time (t) for 3D printed macroporous NorHACA, NorHA, and NorHACA/NorHA discs. The total macromer concentration was kept fixed at 5 wt.% and the NorHACA/NorHA mixture consists of 4.5 wt.% NorHACA and 0.5 wt.% NorHA. (c) Fluorescence images of macroporous NorHA discs (magenta) filled with NorHACA (cyan) over the course of degradation. Scale bar: 1 mm. (d) Cumulative uronic acid and encapsulated bovine serum albumin (BSA) release from filled NorHACA hydrogels over time (t).
