Project description:Gene expression analysis data of human permanent dental pulp tissues
2016-11-22 | GSE75644 | GEO
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.

Project description:Comparative gene expression analysis of the human periodontal ligament and dental pulp in the human permanent teeth
| PRJNA218150 | ENA
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.

Project description:Deciduous and permanent human teeth represent a model system to study ageing of mesenchymal populations. Aging is tightly connected to self-renewal and proliferation and thus, mapping potential molecular differences in these characteristics between populations constitutes an important task. Specifically designed microarray panels were used. We have detected a number of molecules that were differentially expressed in dental pulp mesenchyme from deciduous and permanent teeth extracted from young children and adults, respectively. Among the differentially regulated genes HMGA2, a stem cell-associated marker, stood out as a remarkable example with a robust expression in deciduous pulp cells. In addition to this, we discovered that several proliferation-related genes, including CDC2A and CDK4, were up-regulated in deciduous pulp cells, while matrix genes COL1A1, fibronectin and several signaling molecules, such as VEGF, FGFr-1 and IGFr-1 were up-regulated in the pulp cells from permanent teeth. Taken together, our data suggest that deciduous pulp cells are more robust in self- renewal and proliferation, whereas adult dental pulp cells are more capable of signaling and matrix synthesis.

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.

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.
