Membrane junctions on cat odontoblasts
Archives of Oral Biology, 1975Abstract The odontoblast layer of the pulp was examined after perfusion fixation with buffered aldehydes. Desmosomal junctions occur between only some of the odontoblasts at the predentinal border. Pale cytoplasmic processes similar in morphology to nerve terminals in the intercellular spaces make specialized junctions on the cell bodies of the ...

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.

Journal of Oral Biosciences, 2010
Abstract Odontoblasts, well-polarized columnar cells at the periphery of the dental pulp, originate from neural crest cells. They are primarily involved in dentin formation (dentinogenesis) as sites of the synthesis and secretion of collagenous and non-collagenous matrix proteins, and also participate in the directional transport of Ca 2+ from the ...

Mitochondria in Odontoblastic Processes
Nature, 1966THE odontoblastic processes of human dentin are projections of the odontoblast cytoplasm into spaces in the dense collagenous, highly mineralized dentin matrix1. These projections can be up to several mm in length resulting in the cytoplasm being a long distance (2,000–3,000µ) from the odontoblast nucleus.

Dentin sensitivity and aspiration of odontoblasts
The Journal of the American Dental Association, 1963The aspiration of odontoblasts into the dentinal tubules as an immediate effect of physical stimuli applied to exposed dentin seems to result from loss of sub stance at the distal apertures of the tubules and subsequent outward flow of the tubular contents through capillary action.

Odontoblast differentiation and the formation of the odontoblast layer.
Journal of dental research, 1985Origin, cell kinetics, and phenotypic aspects of odontoblast cell lineage are described. Epithelial-mesenchymal interactions regulate odontoblast differentiation. These interactions appear to be mediated by the extracellular matrix. Possible molecular mechanisms of cell-matrix interactions are discussed.

Human odontoblast response to tooth replantation
The European Journal of Orthodontics, 1981In order to study the main trends in matrix elaboration, and individual variations in these reactions, 55 human first premolars were extracted and replanted for a varying number of weeks, after which they were extracted and fixed for histological interpretation. The same extraction procedure was performed on 22 teeth which were included in the study to

Odontoblasts: developmental aspects
1990Histological, cytological and functional organization determine the identity of odontoblasts. These cells are most often aligned in a single layer at the periphery of the pulp. Fully differentiated odontoblasts are tall, columnar, postmitotic cells with a polarized distribution of their cytoplasmic organelles.

Odontoblasts: Vacuoles and Inclusions
Science, 1961Lipid granules have been found in the cytoplasm of odontoblasts and in the odontoblastic extensions within the dentinal tubules. It is suggested that these granules represent specific activity on the part of the normal cell as well as an increase in number after injury.
