Dental cell type atlas reveals new stem and differentiated cell types in mouse and human teeth

Project description:Reconstruction and engineering of human teeth are the tasks of utmost importance. Here we introduce detailed cellular atlas of the growing and non-growing mouse and human teeth including a condition with caries, which will enhance the field of dental engineering and lead to a better understanding of stem cell niche dynamics enabling tooth growth. We report previously unappreciated cellular complexity of the mouse incisor, including new spatially-restricted stem, progenitor and differentiated populations and compare this model system with the human adult, growing and caries-lesioned teeth. This comparison revealed specific parallelisms in mechanisms of dental growth in humans and mice. Beyond the main mesenchymal and epithelial compartments, we demonstrate a surprising role of the immune system as a mediator of the epithelial-mesenchymal interactions required for proper development. Finally, our results brought new insights into the differentiation of cell lineages producing enamel and dentin, which should be of utmost importance for dental reconstructive engineering.

Dental cell type atlas reveals stem and differentiated cell types in mouse and human teeth.

Project description:Understanding cell types and mechanisms of dental growth is essential for reconstruction and engineering of teeth. Therefore, we investigated cellular composition of growing and non-growing mouse and human teeth. As a result, we report an unappreciated cellular complexity of the continuously-growing mouse incisor, which suggests a coherent model of cell dynamics enabling unarrested growth. This model relies on spatially-restricted stem, progenitor and differentiated populations in the epithelial and mesenchymal compartments underlying the coordinated expansion of two major branches of pulpal cells and diverse epithelial subtypes. Further comparisons of human and mouse teeth yield both parallelisms and differences in tissue heterogeneity and highlight the specifics behind growing and non-growing modes. Despite being similar at a coarse level, mouse and human teeth reveal molecular differences and species-specific cell subtypes suggesting possible evolutionary divergence. Overall, here we provide an atlas of human and mouse teeth with a focus on growth and differentiation.

Comparative gene expression analysis of the human dental pulp in deciduous and permanent teeth

Project description:Human deciduous and permanent teeth exhibit different developmental processes, morphologies, histological characteristics and life cycles. In addition their pulp tissues react differently to external stimuli, such as the pulp sensitivity test, dental trauma and pulp therapy materials. These differences are attributable to their genetic backgrounds. Therefore the purpose of this study is to compare the differences of dental pulp in deciduous and permanent teeth. Pulp samples were obtained from permanent premolars (n=6, aged 11-14 years) and deciduous teeth (n=6, aged 11-14 years). Comparative cDNA microarrary analysis revealed several differences in gene expression between the deciduous and permanent pulp tissues. Each GSM record represents a pulp sample pooled from two teeth samples.

A single cell atlas of human teeth (Pulp scRNA-seq)

Project description:Teeth exert fundamental functions related to mastication and speech. Despite their big biomedical interest, an overall picture of their cellular and molecular composition is still lacking. We here mapped the transcriptional landscape of the various stem cell populations and their microenvironments in human teeth at single-cell resolution. Our analysis identified significant cellular heterogeneity between the various dental tissues. Unexpectedly, we found that the molecular signatures of the stem cell populations were very similar in vivo, and that their distinctive behavior was due to substantial differences between their microenvironments. Furthermore, we showed that the evolutionarily conserved Notch signaling pathway is important for the interactions between dental stem cells and the diverse cell types composing their niches. Our findings reveal that the microenvironmental specificity is responsible for the major functional differences of the stem cells located in the various tooth compartments and open new perspectives towards dental cell-based therapeutic approaches.

Comparative transcriptome profiles of human dental pulp cells from maxillary and mandibular teeth

Project description:PITX1 had a significantly higher expression in the lower teeth compared to the upper teeth and this difference in PITX1 level was more evident in the molars compared to premolars, consistent with data in mouse developing teeth. These show that the differential gene expression during odontogenesis can continue to exist in mature teeth. We suggest that an in vitro study of dental pulp cells should take the differential gene profiles between the mandibular and maxillary teeth into consideration. The knowledge about gene profiling and pathways in mature teeth paves a way to explore a more precise treatment approach in regenerative dentistry.

Comparative gene expression analysis of the human periodontal ligament and dental pulp in the human permanent teeth

Project description:The periodontal ligament(PDL) and dental pulp tissues of human permanent teeth have a number of differences in their developmental processes, histological characteristics and functions. It can be figured out that these differences are attributable to genetic backgrounds of their cells organized tissues. The purpose of this study was to identify the gene-expression profiles and their molecular biological differences of periodontal ligament and dental pulp tissues from the human permanent teeth.

Single cell RNA sequencing reveals deep homology of dental cell types across vertebrates [TJ]

Project description:Here we use single nuclei RNA sequencing (snRNA-seq) of replacement teeth and adjacent oral lamina in Lake Malawi cichlids, species with lifelong whole-tooth replacement, to make two main discoveries. First, despite hundreds of millions of years of evolution, we demonstrate conservation of cell type gene expression across vertebrate teeth (fish, mouse, human). Second, we used an approach that combines marker gene expression and developmental potential of dental cells to uncover the transcriptional signature of stem-like cells in regenerating teeth. Our work underscores the importance of a comparative framework in the study of vertebrate oral and regenerative biology.
