Project description:To evaluate the miRNA and mRNA expression profiles (miRNOME) we identified miRNAs during in vitro osteogenic differentiation of human dental pulp stem cells (DPSC). The DPSCs were cultured in the DMEM + beta-glycerol phosphate, ascorbic acid and dexamethasone for 2 dias to 21days. The microRNA or mRNA expression profiling during the differentiation process was analyzed through hybridizations with Agilent miRNA-microarray (8x15K format).
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
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.
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.
Project description:To evaluate the miRNA and mRNA expression profiles (miRNOME and transcriptome) we reconstructed networks identifying miRNAs and mRNA during in vitro osteogenic differentiation of human dental pulp stem cells (DPSC). The DPSCs were cultured in the DMEM + beta-glycerol phosphate, ascorbic acid and dexamethasone for 2 to 21 days. The microRNA or mRNA expression profiling during the differentiation process was analyzed through hybridizations with Agilent miRNA-microarray (8x15K format) or whole-human genome Agilent microarray (4x44K format).
Project description:Human dental pulp cells have the ability to differentiate into odontoblast cells under various stimuli. The objective of our study is to investigate the efffects of glucose on gene expression of human dental pulp cells that under go odontogenic differentiation. Expression microarray were performed to identify the genes that were affected by short-term and long-term exposure to high glucose levels.
