Most nerve fibers in human dental pulps express both PGP9.5 and neurofilament heavy (NFH). A-D. Confocal micrographs showing two nerve bundles identified by the NFH antibody (B) and two different PGP9.5 antibodies (C, guinea pig polyclonal; D, mouse monoclonal). All the nerve fibers identified by PGP9.5 staining show NFH immunoreactivity. Scale bar, 50 μm.
