Table 2.

Construct viscoelastic compressive properties at t = 5 wk. Fibrocartilage was treated with either C-ABC alone, TGF-β1 alone, the two agents combined, or left untreated (control). The relaxation modulus showed no significant differences in the 50:50 constructs, but was significantly decreased in the combined treated 75:25 constructs compared to controls. The instantaneous modulus and viscosity was highest in the TGF-β1 alone treatment for both cell ratios.
