Ameloblasts Express Type I Collagen during Amelogenesis
, 2014 International audienceEnamel and enameloid, the highly mineralized tooth-covering tissues in living vertebrates, are different in their matrix composition. Enamel, a unique product of ameloblasts, principally contains enamel matrix proteins (EMPs), while

Stem cells for tooth engineering [PDF]
European Cells & Materials, 2008 Tooth development results from sequential and reciprocal interactions between the oral epithelium and the underlying neural crest-derived mesenchyme. The generation of dental structures and/or entire teeth in the laboratory depends upon the manipulation ...

Targeted overexpression of amelotin disrupts the microstructure of dental enamel. [PDF]
PLoS ONE, 2012 We have previously identified amelotin (AMTN) as a novel protein expressed predominantly during the late stages of dental enamel formation, but its role during amelogenesis remains to be determined. In this study we generated transgenic mice that produce

, 2013 In the less mature second molar (M2), N-cadherin was not expressed (A) in the enamel organ (EO) or pulp organ (PO) of three day-old mice. In the more mature first molar (M1), N-cadherin was expressed (B, C).

Reduced protein expression of the Na+/Ca2++K+-Exchanger (SLC24A4) in apical plasma membranes of maturation ameloblasts of fluorotic mice [PDF]
, 2016 Exposure of forming enamel to fluoride results into formation of hypomineralized enamel. We tested whether enamel hypomineralization was caused by lower expression of the NCKX4/SLC24A4 Ca2+-transporter by ameloblasts.

Developmental Dynamics, EarlyView.Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Profiles of Wnt pathway gene expression during tooth morphogenesis
Frontiers in PhysiologyMouse and human genetic studies indicate key roles of the Wnt10a ligand in odontogenesis. Previous studies have identified effectors and regulators of the Wnt signaling pathway actively expressed during key stages of tooth morphogenesis.

On the pattern of ameloblast migration
Cell Proliferation, 1989 Abstract The kinetics of ameloblast cells in continuously growing guinea pig molars were studied using autoradiography. The results showed that there was no direct relationship between ameloblast migration rate and ameloblast production rate, which indicated that ameloblasts actively migrated coronally.

Proteomic signatures of equine dental tooth tissues in ageing and disease
Equine Veterinary Journal, EarlyView.Abstract Background Ageing and dental disease in horses lead to structural and functional deterioration of dental tissues, yet their molecular signatures remain poorly characterised. Understanding how these processes alter the protein composition of enamel, dentin, cementum and pulp is essential for improving equine oral health and identifying ...

Oral and dental status in children with intestinal failure: A descriptive cross‐sectional study
Journal of Parenteral and Enteral Nutrition, EarlyView.Abstract Background Children with intestinal failure often experience feeding difficulties and complex daily care needs, yet their oral and dental health remains underexplored. We aimed to describe oral and dental health characteristics in pediatric intestinal failure.
