Odontoblasts are post-mitotic, neural crest-derived, cells which overtly differentiate according to tooth specific temporo-spatial patterns and secrete predentin-dentin components. Neither the timing nor the molecular mechanisms of their specification are known and the problem of their patterning in the developing jaws is far from being solved.

Expression of amelogenin in odontoblasts
Bone, 2003Amelogenin is the major enamel protein produced by ameloblasts. Its expression has been shown to be down-regulated in ameloblasts of vitamin-D-deficient (-D) rats. The potential expression and localization of amelogenin in odontoblasts and its regulation by vitamin D were investigated in this study.

Odontoblasts in odontogenic tumors
Medical Hypotheses, 2013Odontoblasts are secretory cells displaying epithelial and mesenchymal features, which exist in a monolayer at the interface between the dentin and pulp of a tooth. During embryogenesis, these cells form a dentin shell and throughout life continue to produce dentin while, also acting as sensor cells helping to mediate tooth sensitivity. In this process,

Odontoblasts are post-mitotic cells organized as a layer of palisade cells along the interface between the dental pulp and dentin. They are responsible for the formation of the physiological primary and secondary dentins. They synthesize the organic matrix of type I collagen and actively participate to its mineralization by secreting proteoglycans and ...

Structure and organization of odontoblasts
The Anatomical Record, 1996Differentiation of odontoblasts involves cell-to-cell recognition, contact stabilization involving the formation of attachment specializations, cytoplasmic polarization, development of the protein synthetic and secretory apparatus, and the active transport of mineral ions.

Odontoblasts are dentin-secreting cells that survive for the whole life of a healthy tooth. Once teeth are completely erupted, odontoblasts transform into a mature stage that allows for their functional conservation for decades, while maintaining the capacity for secondary and reactionary dentin secretion.

Nucleoli of human odontoblasts
Archives of Oral Biology, 1972Abstract Nucleoli of human odontoblasts were studied in smears stained with buffered toluidine blue at pH 5, for the demonstration of RNP-containing structures, including nucleoli. The odontoblasts were obtained from 5 premolars removed for orthodontic reasons.

Odontoblast: a mechano‐sensory cell
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2008Abstract Odontoblasts are organized as a single layer of specialized cells responsible for dentine formation and presumably for playing a role in tooth pain transmission. Each cell has an extension running into a dentinal tubule and bathing in the dentinal fluid.

The ultrastructure of human fetal odontoblasts
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1970The ultrastructure of odontoblasts of deciduous teeth from two human fetuses (CRL 159 and 195 mm) was investigated. The human odontoblast is a polarized cell with a characteristic localization of its organelles and demonstrates similarities with odontoblasts from non-human materials.

The fine structure of the mouse odontoblast
Archives of Oral Biology, 1968Abstract A study of the fine structure of the odontoblasts of young mice was undertaken in order to further elucidate the secretory role of this cell in the production of dentine. The observations suggested that fully differentiated odontoblasts possess all of the cytoplasmic characteristics of cells engaged in the production of proteins for external
