The mineral growth can occlude nucleating, and other proteins in the fibril network. From Landis , reproduced with permission. dentin, is a heavily mineralized complex of proteolipids and phospholipids, also containing phosphorylated proteins not typical of those extracted from the mineralized collagen matrix. Much more work remains to be done before a more complete understanding of this mineralized phase is available. For the purposes of this discussion, vertebrate bone could just as easily have represented the mineralization in a fixed polymer matrix of collagen fibrils.
Synthesis begins at the aboral end (Figure 8a, lower right corner) where the tooth forming odontoblasts condense in a layer on the surface of the plumula, a loose collection of collagen fibrils and other extracellular matrix components. Neighboring odontoblasts merge membranes, flatten and form plate-like multinucleated syncytia that project into the matrix with sheet-like membrane bounded structures that continue to extend in the adoral direction throughout the life of the tooth. Using tritiated thymidine, Holland  showed that cell division and expansion of the number of odontoblast nuclei took place only in the plumula at the point of aggregation of the odontoblasts.
A) Initiation of the prism formation. The periostracum is at the upper surface in this model, the calcite crystals begin to grow in the downward direction, utilizing the mineral and organic components within the extrapallial fluid, the solid black base. The interprismatic membranes grow along with the prisms. The solid black arrow on the right indicates the direction of the shell growth in length. (B) Growth of the prismatic layer continues in both thickness and length by the addition of new prism at the leading edge.
