Functional properties of hMSC-laden MeHA constructs at varying cell and macromer densities at 8 weeks. (A) Equilibrium modulus (EY; kPa). (B) Dynamic modulus (|G*|; MPa). (C and D) GAG content (μg/construct and %WW). (E and F) Collagen content (μg/construct and %WW). n = 4/group; white bars = 20M/mL; black bars = 60M/mL; #20M groups (1%, 1.5% and 2%, respectively). *60M groups; p < 0.05. WW, wet weight.
