PDLC response to -glycerophosphate in AO (gray bars) and MO (white bars) hydrogels at 1 (A-C) and 3 weeks (D-F). A,D) ALP activity at 1 (A) and 3 weeks (D), B,E) Relative ENPP1 activity at 1 (B) and 3 weeks (E). C,F) Pyrophosphate concentrations at 1 (C) and 3 weeks (F). G) Mineralization at 3 weeks. H) Representative z-stack images of calcium deposits (Xylenol orange) in hydrogels at 3 weeks. PDLC nuclei are stained blue with Hoechst 33342. Scale bars are 100 μm. N=3–6 hydrogels. Two-way ANOVA with Tukey post hoc. *p<0.05, **p<0.01, ***p<0.001, ****p<0.0001 for between group comparisons, & p<0.01, $ p<0.001, % p<0.0001 for within group comparisons.
