Immunohistochemical analyses of FAM20C and Periostin in mouse periodontal ligament tissues. Immunolocalization for FAM20C (brown color) was present in PDL (a, b), with preferential distribution at the bone surface region (b; arrows) and bone embedded Sharpey’s fibres (b; arrow heads). Periostin was present (brown color) in PDL (c, d) with strong positive signals along the thick PDL collagen, both at the bone surface and cementum surface regions of PDL (d; arrows), and bone embedded Sharpey’s fibres (d; arrow heads). No immunoreactivities were detected when non-immune goat immunoglobulin (IgG) was used as a negative control for anti-FAM20C (e, f), and non-immune rabbit IgG for anti-Periostin (g, h). Scale bar; 200 μm (a, c, e, g), 50 μm (b, d, f, h).
