DNA methylation analysis of three distinct human odontogenic stem cells

Project description:Using the HumanMethylation450 Beadchip, whole genomes of human dental pulp stem cells (DPSCs), periodontal ligament stem cells (PDLSCs), and dental follicle progenitor cells (DFPCs) were compared.The DNA methylation profiles were obtained across approximately 485,512 CpGs in human odontogenic stem cells samples. Samples included DPSCs, DFPCs and PDLSCs from each 4 (12 in total) human individuals.

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.

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.

Induced neural cells from human dental pulp ameliorate functional recovery in a murine model of cerebral infarction

Project description:Human mesenchymal stem cells are a promising cell source for the treatment of stroke. Their primary mechanism of action occurs via neuroprotective effects by trophic factors, anti-inflammatory effects, and immunomodulation. However, the regeneration of damaged neuronal networks by cell transplantation remains still challenging. We hypothesized that cells induced to neural lineages would fit the niche, replace the lesion, and be more effective in improving symptoms compared with stem cells themselves. We investigated the characteristics of induced neural cells from human dental pulp tissue and compared the transplantation effects between these induced neural cells and uninduced dental pulp stem cells. Induced neural cells or dental pulp stem cells were intracerebrally transplanted 5 days after cerebral infarction induced by permanent middle cerebral artery occlusion in immunodeficient mice. Effects on functional recovery were also assessed through behavior testing. We used immunohistochemistry and neuron tracing to analyze the differentiation, axonal extension, and connectivity of transplanted cells to the host’s neural circuit. Transplantation of induced neural cells from human dental pulp ameliorated functional recovery after cerebral infarction compared with dental pulp stem cells. The induced neural cells comprised both neurons and glia and expressed functional voltage, and they were more related to neurogenesis in terms of transcriptomics. Induced neural cells had a higher viability than did dental pulp stem cells in hypoxic culture. We showed that induced neural cells from dental pulp tissue offer a novel therapeutic approach for recovery after cerebral infarction.

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

Dental Pulp Stem Cells Model Early Life and Imprinted DNA Methylation Patterns.

Project description:Early embryonic stages of pluripotency are modeled for epigenomic studies primarily with human embryonic stem cells (ESC) or induced pluripotent stem cells (iPSCs). For analysis of DNA methylation, however, ESCs and iPSCs do not accurately reflect the DNA methylation levels found in preimplantation embryos. Whole genome bisulfite sequencing (WGBS) approaches have revealed the presence of large partially methylated domains (PMDs) covering 30-40% of the genome in oocytes, preimplantation embryos, and placenta. In contrast, ESCs and iPSCs show abnormally high levels of DNA methylation compared to inner cell mass (ICM) or placenta. Here we show that dental pulp stem cells (DPSCs), derived from baby teeth and cultured in serum-containing media, have PMDs and mimic the ICM and placental methylome more closely than iPSCs and ESCs. By principal component analysis, DPSC methylation patterns were more similar to two other neural stem cell types of human derivation (EPI-NCSC and LUHMES) and placenta than were iPSCs, ESCs or other human cell lines (SH-SY5Y, B lymphoblast, IMR90). To test the suitability of DPSCs in modeling epigenetic differences associated with disease, we compared methylation patterns of DPSCs derived from children with chromosome 15q11.2-q13.3 maternal duplication (Dup15q) to controls. Differential methylation region (DMR) analyses revealed the expected Dup15q hypermethylation at the imprinting control region, as well as hypomethylation over SNORD116, and novel DMRs over 147 genes, including several autism candidate genes. Together these data suggest that DPSCs may be useful model for epigenomic and functional studies of human neurodevelopmental disorders.

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.
