Ameloblast - Wikipedia
Each ameloblast is a columnar cell approximately 4 micrometers in diameter, 40 micrometers in length and is hexagonal in cross section. The secretory end of the ameloblast ends in a six-sided pyramid-like projection known as the Tomes' process.
Ameloblast - an overview | ScienceDirect Topics
A single ameloblast patterns the composition of the enamel matrix ribbon that is referred to as a rod, yet these rods are united as a continuum of enamel fabric by the interrod enamel. Each rod and interrod is composed by hundreds of enamel crystallites.

2020年9月23日 · The in-depth characterization of a transition from progenitors to mature ameloblasts may benefit ongoing attempts to establish a system of ameloblast differentiation in vitro or to grow dental...
Endocytosis and Enamel Formation - PMC
The ameloblast membrane resides at the interface between matrix and cell. Enamel formation is controlled by ameloblasts that produce enamel in stages to build the enamel layer (secretory stage) and to reach final mineralization (maturation stage).
Ameloblast - an overview | ScienceDirect Topics
Various epithelial and enamel cells require a specialised structure with directionality from the basal pole to the apical pole. The ameloblast is one of prototypical example of polarized cells.
Ameloblast - an overview | ScienceDirect Topics
An ameloblast is a unique cell type responsible for secreting the enamel matrix during tooth development. It is derived from oral ectodermal cells and is the only cell in teeth at birth that originates from the ectoderm.
Ameloblast | definition of ameloblast by Medical dictionary
ameloblast A columnar epithelial cell that secretes tooth enamel, which has tapering apical surfaces and Tomes processes and which is embedded in the enamel matrix of the tooth.
Molecular Genetics of Ameloblast Cell Lineage - PMC
The presumptive ameloblast begins its life cycle as a proliferative cell, low columnar in shape, separated from adjacent mesenchyme by a basement membrane. Once stimulated, the differentiating ameloblast ceases proliferation and begins to grow in height.

2018年2月26日 · Each ameloblast is responsible for approximately 10,000 ribbons that will eventually coalesce into a single enamel rod. The mineralized ribbons and eventual rods are not straight and, in rodent incisors, will crisscross (decussate).
