Review of Short Phrases and Links

    This Review contains major "Ameloblasts"- related terms, short phrases and links grouped together in the form of Encyclopedia article.


  1. Ameloblasts are forming enamel, while odontoblasts are forming dentin.
  2. Ameloblasts are responsible for the formation of enamel and are lost after the enamel process is complete. (Web site)
  3. Ameloblasts are organized into a layer of highly prismatic cells that secrete tooth enamel proteins such as amelogenin.
  4. In the ameloblasts, the sequence of expression of these fractions varied. (Web site)


  1. This causes the preameloblasts to become ameloblasts and begin their secretion of enamel. (Web site)

Secretory Stage

  1. In the secretory stage, ameloblasts are polarized columnar cells. (Web site)
  2. During the maturation stage the ameloblasts are short, and in contrast to the secretory stage, they absorb proteins from the enamel matrix (8). (Web site)

Tooth Enamel

  1. These are fibroblasts (ligaments and muscles), chondroblasts (cartilage), osteoblasts (bone), ameloblasts (tooth enamel) and odontoblasts (tooth dentine). (Web site)


  1. These results suggest that ameloblastin is an important regulator to maintain the differentiation state of ameloblasts. (Web site)


  1. At some point before the tooth erupts into the mouth, but after the maturation stage, the ameloblasts are broken down.


  1. These signs demonstrate that the ameloblasts have changed their function from production, as in the secretory stage, to transportation. (Web site)


  1. The odontoblasts bear some similarities to the ameloblasts, in that the both cell types are tall and columnar in shape. (Web site)


  1. Enamelin is a large enamel matrix protein secreted by ameloblasts. (Web site)

Surface Ectoderm

  1. Ameloblasts derive from surface ectoderm. (Web site)


  1. These cells give rise to ameloblasts, which produce enamel and the reduced enamel epithelium. (Web site)
  2. Cells of the inner layer become ameloblasts and produce enamel prisms, beginning at the interface with the dental papillae.


  1. These cells, called ameloblasts, do not produce enamel properly in presence of fluoride, and the effect is irreversible. (Web site)
  2. The results indicated that cellular responses to fluoride include elevation of F-actin in ameloblasts.

Developing Teeth

  1. Ameloblastin is a protein expressed predominantly by ameloblasts in developing teeth.
  2. It is secreted by ameloblasts throughout the secretory stage and can readily be isolated from the enamel matrix of developing teeth.


  1. When this first layer is formed, the ameloblasts move away from the dentin, allowing for the development of Tomes processes at the apical pole of the cell.

Enamel Organ

  1. The ameloblasts and enamel organ, including the dental papilla, function similarly.
  2. We also demonstrate that the ameloblasts of the enamel organ are, perhaps, the cells most susceptible to the adverse effects of high dose fluoride exposure. (Web site)
  3. Arch Oral Biol 50:689-94 Tooth enamel is formed by ameloblasts, which are derived from the epithelial cells of the enamel organ.


  1. Here, we show that the sources of the enamelysin transcripts are the ameloblasts of the enamel organ and the odontoblasts of the dental papilla.
  2. The odontoblasts and ameloblasts move away from each other as the dentin and enamel layers increase in thickness. (Web site)
  3. However, Shh signaling is not essential for differentiation of ameloblasts or odontoblasts. (Web site)


  1. Enamel is secreted by special tooth cells called ameloblasts before eruption and is not produced after the tooth erupts.
  2. Ameloblasts - cells which differentiate from ectoderm and secrete enamel during tooth development.
  3. The epithelial stem cell niche is located at the apical end of the tooth and its progeny gives rise to the ameloblasts that form the hard enamel. (Web site)

Enamel Formation

  1. Both the cells which initiated enamel formation, known as ameloblasts, and Tomes processes affect the crystals pattern.
  2. Fluoride induces endoplasmic reticulum stress in ameloblasts responsible for dental enamel formation. (Web site)


  1. The development of teeth involves the formation of dentine, cement, and enamel by odontoblasts, cementoblasts and ameloblasts, respectively. (Web site)
  2. Amelogenesis, or enamel formation, occurs after the first establishment of dentin, via cells known as ameloblasts. (Web site)
  3. Ameloblasts synthesize and secrete the enamel matrix proteins (amelogenin, ameloblastin, and enamelin). (Web site)
