Osteopontin (OPN) immunoreactivity (A–C) and TRAP reactions (D) in sections of the transplanted teeth at 14 days after surgery (B, bone-like tissue; D, dentin; E, enamel space; PC, pulp chamber; PH, pulp horn). (A,B) Newly differentiated odontoblast-like cells in the pulp horn lack an OPN-immunopositive reaction. Note the boundary between the preexisting and tertiary dentin (TD) showing an OPN-positive reaction (arrows). (B) Higher magnification of boxed area labeled by B in A. (C) Higher magnification of boxed area labeled by C in A. The osteoblast-like cells beneath the bone-like tissue matrix show an OPN-positive reaction (arrows). (D) TRAP-positive cells remain around the bone matrix (arrows). Bars: A = 250 μm; B–D = 50 μm.
