Fig. 4. Cross sections of tissue engineered cartilage stained with 5-DTAF with photobleached lines.

Fig. 4

Before shear strains are applied, the photobleached lines appear parallel and vertical (A). Deformed photobleached lines across the thickness of tissue-engineered cartilage clearly demonstrate depth dependent variations in the stiffness of the TE cartilage (B). Under about 25% shear strain, internal failure was observed near the interface between the outer matrix rich region and inner matrix deficient region (C).
