Quantitative analysis of polymer content within the PVA hydrogels prepared using 12 wt % solutions of polymer samples of 6, 17, and 31 kDa and PEG-induced hydrogelation. Hydrogels were incubated in PBS at 4 or 37 °C for 7 days with periodic quantification of polymer chains within the hydrogel through the terminal group quantification method (n = 3; */#p < 0.05, **/##p < 0.01, and ***/###p < 0.001).
