Human Dental Pulp Cell exosomes vs Human iPS Cell exosomes

Project description:Small vesicles, known as exosomes, are secreted from various cell types. Exosomes secreted by mesenchymal stem cells have therapeutic effects against a variety of diseases, and may be able to partially replace stem cell therapies. Previously, we established and characterized human leukocyte antigen (HLA) haplotype homo (HHH) dental pulp cell (DPC) lines from human wisdom teeth. In this report, we purified the exosomes secreted from HHH-DPCs and evaluated their therapeutic potential in a periodontitis model. The exosomes purified from HHH-DPCs showed homogeneous and spherical membrane structures, and showed low but significant expression of HLA class I molecules. The exosomes further promoted proliferation and migration in DPCs. A comparison of miRNAs revealed that the HHH-DPC exosomes contained higher levels of multiple Let-7 family miRNAs compared to HHH-induced pluripotent stem cell (iPSC)-derived exosomes. Finally, the HHH-DPC exosomes showed preventive effects in a mouse model of periodontitis induced by lipopolysaccharides (LPS). In summary, HHH-DPC exosomes expressed HLA molecules which may induce an immune response in HLA-mismatched transplantations. However, they successfully stimulated the proliferation and migration of cells and showed suppressive effects on LPS-induced periodontitis. Therefore, HHH-DPC exosomes show great potential for applications in periodontal treatments.

Characterization of human dental pulp cells grown in chemically defined serum-free medium

Project description:Dental pulp cells obtained from several donors proliferated actively in a serum-free medium STK2. The growth rate of dental pulp cells from most donors was higher in the serum-free medium than that in a medium containing 10% serum. DNA microarray analyses showed that gene expression profile of dental pulp cells grown in the serum-free medium was similar to that of cells grown in a medium containing 10% serum. However, several genes related to cell proliferation were up-regulated in dental pulp cells grown in the serum-free medium.

Insulin-like Growth Factor Binding Protein 7 identified in aged dental pulp by single-cell RNA sequencing

Project description:Dental pulp plays a crucial role for dental health, and dental pulp aging influences their regenerative and reparative function. However, the underlying molecular mechanisms of dental pulp aging are not exhaustively understood, and thereby an in-depth and complete understanding of the aged dental pulp is of foremost importance. This study aimed to explore the heterogeneity of young and aged dental pulp tissue using single-cell RNA sequencing (scRNA-seq).

Differential gene expression of Wnt ligands/Wnt agonist treated human dental pulp stem cells

Project description:Wnt regulates various cell responses. In dental pulp cells, Wnt signaling control cell proliferation, apoptosis, migration and differentiation. Here, the differential gene expression of human dental pulp stem cells treated with Wnt ligands or Wnt agonist was examined using a high throughput RNA sequencing technique. Results demonstrated that Wnt ligands or Wnt agonist altered numerous gene expression in human dental pulp stem cells.

Effect of EtOH on transcriptome signatures in human dental pulp stem cells

Project description:We have performed gene expression microarray analysis to profile transcriptomic signatures affected by EtOH in human dental pulp stem cells Established human dental pulp stem cells were treated with different dose of EtOH (0, 1, 5, 10, 20 and 50mM) for a different time periods (24 and 48 hrs). Total RNA was extracted and subjected to gene expression microarray analysis using Affymetrix human genome 2.0 plus array

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.
