Effect of epithelial depletion of Kdf1 on gene expression alteration during tooth crown development

Project description:In our study, we observed that mice lacking epithelial Kdf1 exhibited rounded and blunt molar cusps, accompanied by abnormal folding of dental epithelium, suggesting that epithelial Kdf1 played a regulatory role in molar crown morphogenesis. Nevertheless, the mechanism within dental epithelium regulating tooth crown morphogenesis remains unclear.

Notch signaling pathway in tooth shape variations throughout evolution

Project description:Evolutionary changes in vertebrates are linked to genetic alterations that often affect tooth-crown shape, which is a criterion of speciation events, especially in mammals. The Notch pathway is highly conserved between species and controls morphogenetic processes in most developing organs, including teeth. Epithelial loss of the Notch-ligand Jagged1 in developing mouse molars affects the location, size and interconnections of their cusps that lead to minor tooth-crown shape modifications convergent to those observed along Muridae evolution. RNA sequencing analysis revealed that these alterations are due to the modulation of more than 2000 genes and that Notch signaling is a hub for significant morphogenetic networks, such as Wnts and Fibroblast Growth Factors. The modeling of these tooth-crown changes in mutant mice, via a three-dimensional metamorphosis approach, allowed prediction of how Jagged1-associated mutations in humans could affect the morphology of their teeth. These results shed new light on Notch/Jagged1-mediated signaling as one of the crucial components for dental variations in evolution.

The cellular basis for epithelial-mesenchymal interaction during mouse tooth development

Project description:In this study, using mouse molar as the model, we developed a dual fluorescence reporter mouse to precisely track and analyze dental epithelium and mesenchyme at single-cell resolution from early embryonic to postnatal stages. Moreover, we constructed the virtual molar explorer (VMEx) to spatially map 15,967 molar-expressed genes and identified that Msx1+ Sdc1+ marked the developing dental papilla while surrounded by Msx1+ Sdc1- molar niche. Through tooth germ reconstitution and organoid culture in vitro and kidney capsule transplantation in vivo, we provided evidence that the Msx1+ Sdc1- dental follicle cells might function as the tooth organizers that promoted epithelium survival and tooth germ organization. Furthermore, the appearance of Msx1+ Sdc1+ dental papilla cells relied on the interaction between dental epithelium and Msx1+ Sdc1- dental follicle cells. Together, our results revealed the cellular dynamics of tooth development in mice and identified that the dental follicle might be the key driver of epithelial-mesenchymal interaction and tooth morphogenesis.

Effect of epithelial depletion of Wnt10a on gene expression alteration during tooth root furcation development

Project description:In our previous study, the knockout of Wnt10a in dental epithelium resulted in the occurrence of taurodontism and root furcation defects, suggesting that epithelial Wnt10a was a pivotal signal to guide root furcation patterning. Nevertheless, the exact mechanisms within dental epithelium leading root furcation development remained to be deeply elucidated. To explore the downstream molecular alterations caused by epithelial Wnt10a ablation, we conducted RNA-Seq of molar epithelium tissue from furcation region.

Wnt/β-catenin signaling, which is activated in odontomas, reduces Sema3A expression to regulate odontogenic epithelial cell proliferation and tooth germ development

Project description:Odontomas are classified as odontogenic benign tumors, which show disorganized dental mineralized hard tissue formation in the jaw, but mechanisms in the induction of odontomas remain to be clarified. Odontomas are also thought to be developmental anomalies of tooth germ, which frequently occur in patients with familial adenomatous polyposis (FAP) involving activation of Wnt/b-catenin signaling. However, the roles of Wnt/b-catenin signaling in odontomas or odontogenic cells remain to be clarified. The current study was conducted to investigate the expression of b-catenin in odontomas and the function of Wnt/b-catenin signaling in odontogenic epithelial cells and tooth germ development. b-catenin frequently accumulated in the nucleus and/or cellular cytoplasm of remaining odontogenic epithelial cells in human odontoma specimens, immunohistochemically. Activation of Wnt/b-catenin signaling inhibited odontogenic epithelial cell proliferation and mouse tooth germ development, while inducing epithelial bud formation in the novel developed epithelial tooth bud culture system derived from mouse tooth germ. We identified Semaphorin 3A (Sema3A) as a downstream molecule of Wnt/b-catenin signaling using DNA microarray analysis and showed that Wnt/b-catenin signaling-dependent reduction of Sema3A expression resulted in suppression of odontogenic epithelial cell proliferation. Novel developed epithelial tooth bud culture system revealed that Sema3A expression is required in epithelial budding morphogenesis. These results suggest that Wnt/b-catenin signaling negatively regulates odontogenic epithelial cell proliferation and tooth germ development through decreased-Sema3A expression, and aberrant activation of Wnt/b-catenin signaling may be associated with the formation of odontomas.

Single cell transcriptional profiling of mouse molar and incisor tooth assembloids

Project description:Throughout the various stages of tooth development, reciprocal epithelial-mesenchymal interactions are the driving force, for instance crucially involved in the differentiation of mature enamel-forming ameloblasts and dentin-producing odontoblasts. Here we established mouse tooth ‘assembloids’, comprised of tooth organoid-derived dental epithelial cells (from mouse molars and incisors) cultured together with molar dental pulp stem cells (DPSCs), to mimic these developmental interactions. Assembloids from both tooth types were grown both in basal- and differentiation-inducing conditions. Single cell transcriptomics analysis was applied to in detail characterize and validate the newly developed mouse tooth assembloid model and evaluate the induced differentiation processes.

Developmental plasticity of stem cells in tooth and taste bud renewal

Project description:We use the continuously replacing dentition of Lake Malawi cichlid fishes to understand de-novo tooth replacement in adult vertebrates. In this system, each tooth is replaced in a one-for-one fashion every ~50 days. Here, we explore the source of epithelial stem cells for tooth replacement.

Transcriptome of mature Arabidopsis thaliana crown galls

Project description:This study describes physiological changes, morphological adaptations and the regulation of pathogen defense responses in Arabidopsis crown galls. Crown gall development was induced on intact plants under most natural conditions with Agrobacterium tumefaciens. Differential gene expression and the metabolite pattern was determined by comparing crown galls with mock-inoculated inflorescence stalk segments of the same age.
