Figure 5: Relationship between pentosidine deposition and biomechanical properties of rat Achilles tendons.(A) Ultimate stress was negatively correlated with the percentage of the extracellular matrix (ECM)area stained by an anti-pentosidine antibody (r=-0.59, p<0.05). (B) Young’s elastic modulus had no correlation with the percentage of pentosidine-positive ECM area. (C) No significant correlation was observed between toughness and the pentosidine-positive area.
