Figure 1. AMTN, ODAM and SCPPPQ1 localize at the cell-tooth interface.

(a) Micrograph from a histological section stained with hematoxylin and eosin showing apposition of the junctional epithelium (JE) to the enamel, seen here as a space (ES) following decalcification. The inset is a higher magnification of the JE cells (*). The arrows point to the position of the associated specialized basal lamina (sBL). (b–d) Immunofluorescence preparations for AMTN, ODAM and SCPPPQ1 imaged by Structured Illumination Microscopy (SIM) indicate that the three proteins reside in the sBL. ODAM also exhibits a cell-associated labeling (arrowheads). Proteins stained in green, nuclei in blue using DAPI. Scale bars = 10 μm.
