Viability of rat fibroblasts in in vitro cytocompatibility testing of 6 mol % DBA-containing hydrogel degradation products. Rows correspond to the hydrogel TGM wt % (10 or 20 wt %), while columns refer to the PAMAM crosslinker used at a 1:1 amine:epoxy mol ratio (P-1440 or P-2600). Data are reported as means ± standard deviation for a sample size of n = 6. * and # indicate statistical significance (p<0.05) within and between timepoints, respectively.
