Gene expressions of MSCs encapsulated in hydrogels following 8 days of in vitro culture under chondrogenic conditions. Statistical significance of soft and stiff hydrogels are compared against soft and stiff controls, respectively; *p < 0.05. All samples are normalized against stiff control (13% (w/v) PEG.
