Project description:Purpose: The goal of this study was to characterize the gingival oral barrier immunity of mouse periodontitis gingiva. Method: A silk thread (ligature) was tied wround the mouse maxillary molar. Mouse palatal gingiva was harvested at 1 days after the ligature placement. Gingival cells were harvested and subjected to 10X Genomix scRNA-seq. Cell Ranger processed data were analysed.
Project description:Organoid models provide powerful tools to study tissue biology and development in a dish. Here, we established first-time organoid models from early-postnatal (postnatal day 7) mouse molar and incisor, capable of differentiation toward ameloblast-like cells in vitro. To more in detail characterise organoids from mouse molar and incisor, bulk RNA-sequencing was performed on the following (1) early passage (passage 0) organoids from both tooth types grown in basal tooth organoid medium (TOM) with or without addition of exogenous epidermal growth factor (EGF); and (2) late passage (passage 5) organoids grown in TOM+EGF or differentiation medium (DM).

Project description:Numerous genes that play important regulative roles during tooth development in mice have been identified. However, very little is known about gene expression and function in human odontogenesis. We used microarrays to detail the global programme of gene expression underlying tooth development and identified distinct classes of up-regulated genes during in the tooth germs. Tooth germs of molar, incisor, and canine at the cap stage were dissected, respectively, from 12-week-old human embryonic oral cavity for RNA extraction and hybridization on Affymetrix microarrays. We sought to screen for the genes that are strongly expressed in the dental tissues and analysis if these genes related to mammalian tooth development and tooth abnormalities.
Project description:We have isolated protein extracts from four major types of human teeth i.e. Molar,Premolar,Incisor and Canine through deminralization process. Within these four extrcats, we identified and quatitated differential protein abundance through MS based approach.
Project description:The goal of this study is to use a rapid method for oral neutrophil isolation and use a transcriptomics approach to characterize and compare the neutrophil gene expression profile in the blood and oral compartment of healthy individuals, chronic periodontitis patients and refractory periodontitis patients. Total RNA obtained from isolated neutrophils from blood and oral samples of Healthy patients, chronic periodontits patients and refractory periodontitis patients
