FIG. 8.

Compressive Young's modulus of engineered cartilage constructs. Wrist constructs were the stiffest of all groups, followed by Knee, 2M, and 3S2M tissues. The 2S, 3S, and 2S2M groups possessed the lowest compressive properties. *p < 0.05 vs. d0; **p < 0.05 vs. d14; ***p < 0.05 vs. d28; †p < 0.05 vs. all single-layer groups of same time point; ‡p <0.05 vs. all double-layer groups of same time point; Δp < 0.05 vs. all other knee groups of same time point; ▾p < 0.05 vs. all other groups of same time point.
