Figure 1

(a) The schematics of the (full thickness) perpendicular sections and parallel sections of articular cartilage. (b) The visible image of a perpendicular section from the FTIRI microscope. (c) The visible images of four parallel sections at four different tissue depths from the FTIRI microscope: 18μm (superficial zone), 102μm (transitional zone), 258μm (upper radial zone), and 528μm (lower radial zone). The black boxes in (b) and (c) indicate the regions where the FTIRI experiments were carried out. The non-calcified tissue is about 650μm thick. (A.S. = articular surface; SZ = superficial zone; TZ = transitional zone; RZ = radial zone)
