(A) Cumulative release of BSA as an effect of the cross-linker geometry employed to form the HA hydrogels. SEM images showing pore structures of lyophilized HA hydrogels: (B) linear cross-linker, (C) four-arm cross-linker, and (D) eight-arm cross-linker. (E) Quantification of porosity. (F) Rheological quantification of the shear elastic modulus in HA-only and heparinized HA (denoted with “HP”) hydrogels as an effect of cross-linker type. Statistical significance: **p < 0.05. Scale bars = 200 μm.
