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

The Anatomical Record, EarlyView.Abstract Sharks possess varied diets and different prey capture mechanisms. As a result, the group exhibits a significant diversity in dental morphology, also reflecting the internal structures of the teeth. Internal dental anatomy points to the existence of three histotypes in elasmobranch phylogeny: orthodont, osteodont, and pseudoosteodont ...

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.

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.

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.

Jaw‐specific stem cell dynamics are associated with distinct enamel architecture in mouse incisors
Developmental Dynamics, EarlyView.Abstract Background The continuously growing mouse incisor serves as a model for stem cell‐driven tooth renewal. Although mice possess maxillary and mandibular incisors, most studies have focused on the mandible. Potential differences in structure and renewal between these serially homologous organs remain insufficiently characterized.

Frontiers in Bioengineering and Biotechnology, 2022 The transcriptional regulation of induced pluripotent stem cells (iPSCs) holds promise for their directed differentiation into ameloblasts, which are usually lost after tooth eruption.

Developmental Dynamics, EarlyView.Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...

Frontiers in Physiology, 2017 Na+:K+:2Cl− cotransporters (NKCCs) belong to the SLC12A family of cation-coupled Cl− transporters. We investigated whether enamel-producing mouse ameloblasts express NKCCs.

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 ...
