Representative release profiles for cumulative release of DNA complexes from HA-based gels. Release studies performed in the presence of PBS (a) or 150 U/ml HAase (b) The percentages of PEG and HA in the hydrogel are: PEG6: HA1 (■), and PEG8:HA1 (▲) for mechanically stable gels and PEG2:HA1 (□), PEG4:HA2 (○), and PEG4:HA4 (△) for fully degradable gels.
