Figure 6. — Swelling and degradation behavior of the hydrogels. (A) Swelling in PBS conditions. * indicates significance for PdBT/MMP-HAV group compared to PdBT control at Day 21 (n = 3–4, P < 0.05). ^ǂ indicates significance between PdBT/MMP-HAV Days 14 and 21 compared to Day 1. (B) Percent mass loss in PBS conditions. ^ indicates significance of PdBT/HAV compared to PdBT/MMP-HAV at Day 1. ^ǂ indicates significance between PdBT/MMP-HAV Day 7 and PdBT/MMP-HAV Day 1. * indicates significance between PdBT/HAV Day 14 and PdBT at that timepoint. ^# indicates significant difference between PdBT/HAV Day 14 and PdBT/HAV Days 1 and 3 (n = 3–4, P < 0.05). (C) Swelling in collagenase-containing conditions. * indicates significance of PdBT/MMP-HAV at Day 21 compared to PdBT at Day 21 and ⁺ indicates significance compared to PdBT/HAV at Day 21. ^ǂ indicates significance of PdBT/MMP-HAV Day 21 with respect to PdBT/MMP-HAV at Days 7 and 14. (D) Percent mass loss in collagenase containing conditions. After study initiation, no significant mass loss was observed between groups (n = 3–4, P < 0.05)
