Figure 7: Schematic model of the distribution of AMTN, ODAM and SCPPPQ1 within the supramolecular organisation of the specialized basal lamina (sBL).

The two boxed above in images are representative immunogold labelings for ODAM (skewed toward the cells) and SCPPPQ1 (skewed toward the tooth surface) over the sBL from the maturation stage enamel organ and the junctional epithelium. The model attempts to integrate the observed differential distribution of the three proteins within a laminin-332 background whose arrangement within the unique extracellular matrix constituted by the sBL remains to be clarified.
