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

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.

Dental Pulp Stem Cells LC-MS/MS analysis

Project description:This study focuses on the impact of ECM (extra-cellular matrix) over cell processes such as proliferation, differentiation or mineralization which is more specifically related to our dental pulp cells. We cultured these dental pulp stem cells (DPSC) in mineralization growth or normal growth conditions. After 21 days, cells were incubated in decellularized solution until no intact cells are seen. After ECM was washed, we studied the mineralization associated to these two different ECM. Matrisome proteins were identified through proteomics. DPSC matrisome is composed of 225 individual different proteins. We classified them according to different categories, the 3 core matrisome categories: glycoproteins, collagens, proteoglycans and the 3 matrisome associated proteins categories: the regulators, affiliated and secreted. When comparing the proteins in the N-ECM and OM-ECM, most of the core matrisome proteins are downregulated in OM conditions, except 3 glycoproteins, as well as regulators and secreted factors. However, annexins were found to be upregulated in OM condition. Cell adhesion, tensile strength and growth factor binding are over-represented in NM ECM. The collagen group and glycoproteins were higher in N-ECM than OM-ECM Thereafter, gingival stem cells (GSC), the less inherit osteogenic potency cells, were seeded on these N-ECM and OM-ECM. When GSCs were seeded on DPSC-derived ECM, the OM-ECM dramatically promoted mineral deposition compared with N-ECM. We hypothesize that annexins could participate in the osteogenic inductive properties. ECM plays a pivotal role in many physiological processes, it regulates cells behavior and can orient cell differentiation. Dental pulp and oral mucosa share embryological origins but differ in their reactions to insults. Dental pulp can mineralize while oral mucosa heals ad integrum. We hypothesize that ECM participate in these characteristics.

Proteomic profile of human stem cells from dental pulp and periodontal ligament

Project description:Dental stem cells isolated from oral tissues have been shown to provide with high proliferation ability and multi-lineage differentiation potential. Although the dental stem cells possess the potential of nerve regeneration, the specific expression profile of dental pulp stem cells (DPSCs) and periodontal ligament stem cells (PDLSCs) are still unclear. Here, DPSCs and PDLSCs, collected from the same tooth with 3 donors, were tested for high-throughput protein profiles by combining two-dimensional gel proteomics and TMT-based proteomics.

Different osteogenic differentiation behavior of canine mesenchymal stem cells derived from bone marrow and dental pulp: the proteomics profile

Project description:Although various sources of cMSCs show similar characteristics, they are different in osteogenic potential due to their original cellular sources. Thus, this study was designed to globally explore and analyze the in vitro differentiation potential and behavior of canine bone-marrow derived mesenchymal stem cells (cBM-MSCs) and canine dental pulp stem cells (cDPSCs) toward osteogenic lineage. Global study of an in vitro osteogenic differentiation potential of the isolated cells was performed using proteomic-based analysis through mass spectrometry with dimethyl labelling method at day 7 and 14 post-induction, comparing with undifferentiated cells. The obtained results could be used as a comprehensive data and principal knowledge of the osteogenic differentiation potential of cBM-MSCs and cDPSCs in vitro and the trend of MSC-based tissue engineering for osteogenic regenerative therapy, concentrating on cMSCs application.

Bone marrow-derived and dental pulp-derived human mesenchymal stem cell RNA-Seq

Project description:Lineage commitment and tumorigenesis specify adult stem cells from different tissues or organs. To gain insight into the mechanism of this programming, phenotypic, functional and transcriptome analyses were performed in mesenchymal stem cells derived from human dental pulp (DPSCs) and bone marrow (BMSCs). DPSCs and BMSCs had similar morphologies and flow cytometric profiles, and were capable of tri-lineage differentiation into osteoblast, adipocyte and chondocyte. However, compared with BMSCs, DPSCs increased in osteogenic potential, decreased in adipogenic potential, and formed dentin-pulp-like complexes in vivo. Genome-wide RNA-seq and differential expression analysis revealed that signalings such as, phosphatase and tensin homolog (PTEN)/PI3K/AKT pathway, and cancer-related pathway were different in both cells. Differential PTEN expression, higher in DPSCs than BMSCs, was responsible for the lineage commitment and tumorigenesis differences in both cells. Besides, BMSCs decreased in PTEN DNA methylation compared to DPSCs, which was mediated by increased DNA (cytosine-5) methyltransferase 3B (DNMT3B) expression. Furthermore, histone methyltransferase G9a mediated repressive epigenetic mark H3K9Me2 was selectively enriched in BMSCs. Moreover, DPSCs were more resistant to oncogenic transformation than BMSCs. To link lineage commitment with tumorigenesis, we demonstrated that DPSCs were more resistant to oncogenic transformation than BMSCs and PTEN deficiency increased the sensitivity of DPSCs for tumorigenic transformation. The results help understanding the roles of the epigenetic factors in lineage commitment and tumorigenesis and also for therapeutic uses of adult stem cells.
