DNA quantification of ATDC5 cells encapsulated inside 6.5% (w/v) PEG hydrogels varying in the cross-linker type (F or R) and RGD content, and cultured over time in 4C chondrogenic medium. 6.5R0 = R cross-linker + 0 µM RGD; 6.5RR = R cross-linker + 150 µM RGD; 6.5F0 = F cross-linker + 0 µM RGD; 6.5FR = F cross-linker + 150 µM RGD. Results depicted as mean ± SD (Two-way ANOVA; n = 3; #FR p < 0.01 compared to FR formulation at 1 week; %1WK p < 0.001 compared to the hydrogel at 1 week with the same composition. $0WK p < 0.001 compared to the hydrogel at 0 week with the same composition; *** p < 0.001).
