Immunohistochemical staining of regenerated PDL-like tissue in Group A. Immunohistochemical staining for collagen I (a), fibronectin (b), and osteocalcin (c) of the regenerated PDL-like tissue. The periodontium-like characteristics of the neo-tissue could be confirmed by positive immunohistochemical staining for collagen type I, fibronectin and osteocalcin. Bar scales 100 μm for a–c
