Figure 2From: Unmyelinated nerve fibers in the human dental pulp express markers for myelinated fibers and show sodium channel accumulationsMost 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.Back to article page
