Figure 4. Photomicrographs showing localization of CP in cementoblastoma-derived cells. Positive immunostaining of CP in cementoblastoma-derived (A) and periodontal ligament cells (B). Alveolar bone-derived cells staining appears close to the background levels (C).. Controls using pre-immune rabbit serum were negative for the 3 cell types (D, E, and F for cementoblastoma, periodontal ligament cells, and alveolar bone-derived cells, respectively). Magnification 20X. Bar = 100 µm.
