A–D. Young's Modulus (n = 10–25) (A), Dynamic Modulus (n = 10–25) (B), GAG Content (n 9–19) (C), and Collagen Content (n = 9–21) (D) normalized to respective maturity point tissue properties (n = 26–32), and averaged across 2 (Continued Culture, MOPS-4) or 4 (MOPS-25) independent studies for samples preserved for 14 and 28 days with. ^indicates significant difference from maturity point and letters indicate significantly different groups (p < 0.05).
