Degradation of mPEG-PLGA and BOX hydrogels in vitro. Both mPEG-PLGA and BOX hydrogels at a concentration of 20 wt% were immersed in 15 ml of PBS (a), normal saline (b) or distilled water (c). The mass loss of both copolymers was measured at 37 °C in a 4-week incubation period. *P < 0.05, the statistical comparisons for BOX hydrogel versus mPEG-PLGA hydrogel
