Compression properties of tissue engineered neocartilage constructs represented by aggregate modulus, permeability, and Poisson’s ratio, and tensile properties represented by Young’s modulus and UTS. Values are mean ± 95% CI. Fisher’s post hoc testing was applied if P < 0.05. Groups not connected by the same letter are significantly different. See Results section for details.
