FIG. 4.

Mechanical properties. The compressive modulus (A), magnitude of the complex shear modulus (B), and phase shift angle (C) of both acellular and DZC-seeded scaffolds were determined. The cell-seeded groups consistently exhibited higher shear modulus and phase shift angle as compared with their respective acellular controls (^{^}p<0.05, n=3). Moreover, by day 28, both a higher shear modulus and phase shift angle were found in the alginate+HA scaffolds as compared with the alginate control (*p<0.05). DZC, deep-zone chondrocytes.
