Time-dependent material behavior of hydrogels during collagenase digestion. (A) The thickness of the degradable group was reduced by 41% during incubation (p < 0.001), whereas the nondegradable group was unaltered (p = 0.2). (B) The equilibrium modulus of the degradable group was reduced by 42% during incubation (p < 0.001), whereas the nondegradable group was unaltered (p = 0.5). Most alterations in the degradable group occurred in the first 2 days of collagenase digestion. Bars represent standard deviation (*p < 0.05).
