gravimetric mass loss over time for base-catalyzed degradation studies (0.2 m naoh, 37 c, 60 rpm) for (a) linear-pcl-based and (b) star-pcl-based scaffolds. (c) mass loss at 72 hr was compared for all scaffold compositions; *p < 0.05, **p < 0.01, #p > 0.05. note: the black color-coded statistics were compared to lpcl control while orange color-coded statistics were compared to the l/l composition. (d) representative photos of specimens at different timepoints during degradation study.
