Figure 6

Immunohistochemical staining with HBME-1, CD68, CD163, and CD86. A1 to A5 show the results of HE staining, B1 to B5 show CD68 staining, C1 to C5 show CD163 staining, and D1 to D5 show CD86 staining. (B2) CD68-positive cells were found at sites of accumulation of lymphocytes (arrow). (B3 and B4) The circles show PGA bundles and (1)–(3) show positive cells: (1) cells between the fibers in the PGA bundles, (2) cells in the space between the PGA bundles, and (3) cells at the surface of the PGA fiber. All scale bars are 100 μm.
