FIG. 6.

Histological analyses of tissue engineered cartilage. The structure and extracellular matrix (ECM) deposition of engineered cartilage tissue is shown at 2.5×magnification (scale bar is 1000 μm) (A). High-magnification images showing the ECM of unstained sections (B), immunostained type II collagen (C) and type I collagen (D), safranin-O staining for proteoglycan (E), and hematoxylin and eosin (H&E) for overall cellularity (F) of representative samples are shown at 10×(scale bar is 100 μm).
