DNA content of cell-laden PEG hydrogels cultured in GM in vitro over time varying in the percentage of macromer, the cross-linker type, and the incorporation or lack of the cell binding motif, RGD, or scrambled peptide, RDG. Results are presented as mean ± SD (n = 3; # p < 0.001 when comparing the hydrogel composition at 1 week to its 4 week counterpart; § p < 0.01 compared to 1 week DNA content of unmarked hydrogels; *** p <0.001 when comparing otherwise similar hydrogels with and without RGD at 4 weeks).
