Table 1.

Representative ECM synthesis parameters previously derived from a cartilage tissue engineering model applied to published experimental data.9 Growth (α) and decay (β) rates are further extracted in this work from the Deterministic Control Model. Note: PGA = polyglycolic acid scaffold; BAC = bovine articular cartilage;τECM = matrix molecule characteristic time constants; dw = dry weight; ww = wet weight.
