Biomechanical properties of neocartilage constructs treated with combinations of 4-αPDD, ouabain, and ionomycin. (A) Aggregate modulus, (B) shear modulus, (C) tensile Young's modulus, and (D) tensile UTS. Abbreviations as follows: 4-αPDD (4α), ouabain (Ou), and ionomycin (Io). No statistical significance was found in any of the mechanical properties.
