Tooth histotype and enameloid microstructure of Priohybodus arambourgi d'Erasmo, 1960 (Elasmobranchii: Hybodontiformes) from the Late Jurassic of northeastern Brazil

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 ...

Optimized micro‐sized cell sphere‐matrix niche co‐aggregates promote efficient oral and craniomaxillofacial bone regeneration

BMEMat, EarlyView.
The construct of cell‐niche co‐aggregates (GelMA‐SHED sphere‐DDMPs) promotes cranial and periodontal bone regeneration and ensures angiogenic‐osteogenic coupling by downregulating miR‐34c‐5p to enhance the expression of NOTCH1 and its intracellular domain (NICD).

Atlas of human dental pulp cells at multiple spatial and temporal levels based on single-cell sequencing analysis

Frontiers in Physiology, 2022
The dental pulp plays a crucial role in the long-term maintenance of tooth function. The progress of endodontic treatment and pulp tissue regeneration engineering has made pulp-regeneration therapy promising in clinical practice.

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

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.

The Effect of Simvastatin on Odontoblastic Differentiation of Human Dental Pulp Stem Cells: An In Vitro Study

Dentistry Journal
Objectives: The aim of the current in vitro study was to assess the effect of simvastatin on the early-stage differentiation of human dental pulp stem cells (hDPSCs) in an odontogenic pattern by evaluating the expression of specific odontogenic-related ...

Chitin scaffolds derived from the marine demosponge Aplysina fistularis stimulate the differentiation of dental pulp stem cells

Frontiers in Bioengineering and Biotechnology, 2023
The use of stem cells for tissue regeneration is a prominent trend in regenerative medicine and tissue engineering. In particular, dental pulp stem cells (DPSCs) have garnered considerable attention.

Polarity of Mature Human Odontoblasts

Journal of Dental Research, 2013
Odontoblast polarization is based on histological appearance as columnar cells with asymmetric disposition of organelles and plasma membrane domains. However, little is known about the odontoblast plasma membrane organization. We investigated odontoblast membrane polarity using influenza virus hemagglutinin and vesicular stomatitis virus glycoprotein ...

Expression and function of dopamine in odontoblasts [PDF]

Journal of Cellular Physiology, 2019
AbstractDopamine (DA) is produced from tyrosine by tyrosine hydroxylase (TH). A recent study has reported that DA promotes the mineralization of murine preosteoblasts. However, the role of DA in odontoblasts has not been examined. Therefore, in this investigation, we researched the expression of TH and DA in odontoblasts and the effects of DA on the ...

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.

Autophagic Activity and Aging in Human Odontoblasts

, 2011
Odontoblasts are long-lived post-mitotic cells in the dental pulp, whose function is to form and maintain dentin. The survival mechanisms that preserve the viability of terminally differentiated odontoblasts during the life of a healthy tooth have not ...
