Project description:To explore the functions of MXRA5 for DPSC proliferation and migration, we established DPSC in which MXRA5 has been knocked down by 2 independent siRNAs.We then performed gene expression profiling analysis using data obtained from RNA-seq of DPSC-si-control, DPSC-siMXRA5-1, and DPSC-siMXRA5-2.

Project description:Stem cell-based therapy is an alternative strategy for brain repair. Various cell types have been investigated and dental pulp stem cells (DPSC) have been identified as promising candidates. These multipotent stem cells are found in the dental pulp tissue of molar teeth. They are clinically easily obtained, have a high proliferative rate, and possess neurogenic potential due to their mesoectodermal origin. Here, overexpression of octamer-binding transcription factor 4 (OCT4) in combination with neural conditions was used to reprogram human DPSC along the neural lineage. Transcriptomic analysis of differentially-expressed genes highlighted the expression of genes associated with neural and neuronal functions in the OCT4-overexpressing DPSC following neural induction.

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: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.

Project description:HGF-CM increases the proliferation and migration ability of DPSC (Dental pulp stem cells) in a dosage dependent manner, and facilitates the mineralization of DPSC by upregulating odotogenic genes. Although lack of in vitro evidence, DPSC and hGF-CM could be a promising combination for pulp regeneration in the future.

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:A major challenge to the study and treatment of neurogenetic syndromes is the difficulty in gaining access to live neurons from individuals with these disorders. Although other sources of stem cells are currently available for differentiation into neurons, these can involve invasive procedures and be difficult or expensive to generate limiting their use on a broad scale, especially for rare syndromes which may not be well represented in the local population. Dental pulp stem cells (DPSC) are neural crest derived multipotent stem cells that reside deep the pulp of shed (baby) teeth and have the potential for broad use in the study of neurogenetic disease. Here, we use DPSC-derived neurons to investigate the developmental differences between neurotypical controls and Prader-Willi syndrome (PWS) by single cell sequencing using SPLiT-Seq.

Project description:Purpose: To compare the transcriptional changes of genes in dental pulp tissues with different degrees of inflammatory severity and investigate the role of RAD54B in inflamed human dental pulp cells (hDPCs) Methods: Normal, carious, and pulpitis human dental pulp tissues were collected. Total RNA extracted were subjected to RNA-sequencing and gene expression profiles were further studied by Gene Ontology (GO) and KEGG pathway analysis. DEGs (differentially expressed genes) in homologous recombination repair (HRR) were validated with qRT-PCR. The expression of RAD54B and TNF-α in human dental pulp tissues was detected by immunohistochemistry. HDPCs were cultured and RAD54B level in hDPCs was detected after LPS stimulation using western blot. CCK-8 was applied to investigate the cell proliferation of hDPCs transfected with negative control (Nc) small interfering RNA (siRNA), RAD54B siRNA, P53 siRNA or both siRNAs with or without LPS stimulation. Flow cytometry was applied to detect the cell cycle distribution, and western blot and immunofluorescence were utilized to analyze the expression of RAD54B, P53 and P21 under the above treatments. One-way and two-way ANOVA followed by LSD posttest were used for statistical analysis. Results: RNA-sequencing results identified DEGs among three groups. KEGG pathway analysis revealed enrichment of DEGs in Replication and Repair pathway. HRR and non-homologous end joining (NHEJ) components were further verified and qRT-PCR results were basically consistent with the sequencing data. RAD54B, a HRR accessory factor highly expressed in carious and pulpitis tissues compared to normal pulp, was chosen as our gene of interest. High RAD54B expression was confirmed in inflamed human dental pulp tissues and LPS-stimulated hDPCs. Upon RAD54B knockdown, P53 and P21 expressions in hDPCs were upregulated whereas the cell proliferation was significantly downregulated, accompanied with increased G2/M phase arrest. After inhibiting P53 expression in RAD54B-knockdown hDPCs, P21 expression and cell proliferation were reversed. Conclusions: Gene expression profiles of normal, carious and pulpitis human dental pulp tissues were revealed. HRR components was elucidated to function in dental pulp inflammation. Among HRR DEGs, RAD54B could regulate the cell proliferation of inflamed hDPCs via P53/P21 signaling. This research not only deepens our understanding of dental pulp inflammation but also provides a new insight to clarify the underlying mechanisms.
