FIG. 9.
Local Young's modulus for Knee (A), Wrist (B), and bilayered constructs (C). Knee and Wrist constructs possessed similar U-shaped profiles, with Wrist constructs being significantly stiffer at all locations compared to Knee. Bilayered constructs appeared to have a depth-dependent compressive EY qualitatively similar to that of native articular cartilage (D). *p < 0.05 vs. SZC layer (z/h0 = 0–0.5); †p < 0.05 for 3S2M vs. 2S2M; ‡p < 0.05 vs. edges (z/h0 = 0–0.1, 0.9–1); ▾p < 0.05 vs. all respective depths in Knee group.
