Physical properties of dynamically tunable hydrogels. (a) Swelling ratios (N=4) and (b) mass loss (N=4) of hydrogels without cells in DMEM over time. (c) Elastic modulus changes of hMSC encapsulated hydrogel constructs in growth media over time (N=4). *p<0.05 compared to soft hydrogels (SO) at a specific time point. **p<0.05 compared to soft hydrogels (SO) within a specific group.
