Effect of FDC-SP on Gene Expression of Human Periodontal Ligament Cells

ABSTRACT: Previous research has reported that FDC-SP had similar molecular properties to statherin, a protein exists in saliva which plays important roles in preventing Ca precipitation. Further biomolecular study has suggested that the expression of FDC-SP may be associated with periodontal ligament (PDL) phenotype expression. Therefore, we hypothesized that FDC-SP may play specific roles in the inhibition of calcium precipitation during periodontal regeneration, as well as affect phenotype expression of periodontal ligament cells (PDLCs) during the differentiation process. To investigate this, we applied microarray technology to identify gene expression changes in hPDLCs transfected with FDC-SP and then clustered them according to their biological functions.

To investigate this, we applied microarray technology to identify gene expression changes in hPDLCs transfected with FDC-SP and then clustered them according to their biological functions. We firstly established a recombinant lentiviral vector containing FDC-SP and obtained safe and efficient FDC-SP overexpression in human periodontal ligament cells (hPDLCs). After that, we applied Agilent Whole Human Genome Oligo Microarray (4M-CM-^W44K) to identify differentially expressed genes between empty vector-transfected hPDLCs and FDC-SP -transfected ones and then clustered them according to their biological functions. 3 independent experiments were performed and the empty vector-transfected hPDLCs were used as control.

scRNA-seq analysis of murine periodontal ligament

Project description:Periodontal tissue supports teeth in the alveolar bone socket via fibrous attachment of the periodontal ligament (PDL). The PDL contains many stromal cell types, including osteoblasts, cementoblasts, periodontal fibroblasts, and stem/progenitor cells. However, the characteristics and lineage hierarchy of each cell type remain poorly defined. Here we present a single-cell atlas of PDL, highlighting diverse cell populations in PDL.

Comparative gene expression analysis of dental follicle and periodontal ligament in humans

Project description:The aim of this study was to evaluate and compare the gene expression profiles of dental follicle and periodontal ligament in humans, which can possibly explain their functions of dental follicle and PDL such as eruption coordination and stress resorption. That may apply this information to clinical problem like eruption disturbance and to periodontal tissue engineering. PDL samples were obtained from permanent premolars (n=11) and dental follicle samples were obtained during extraction of supernumerary teeth (n=4). Comparative cDNA microarray analysis revealed several differences in gene expression between permanent PDL and dental follicles.

Function of chemokine (CXC motif) ligand 12 in periodontal ligament fibroblasts

Project description:The periodontal ligament (PDL) is one of the connective tissues located between the tooth and bone. It is characterized by rapid turnover. Periodontal ligament fibroblasts (PDLFs) play major roles in the rapid turnover of the PDL. Microarray analysis of human PDLFs (HPDLFs) and human dermal fibroblasts (HDFs) revealed markedly high expression of chemokine (CXC motif) ligand 12 (CXCL12) in the HPDLFs, which plays an important role in the migration of mesenchymal stem cells (MSCs). The function of CXCL12 in the periodontal ligament was investigated in HPDLFs. CXCL12 in HPDLFs and HDFs was examined by microarray, RT-PCR, qRT-PCR and ELISA. It was also immunohistochemically examined in the PDL in vivo. Chemotactic ability of CXCL12 was evaluated both in PDLFs and HDFs with migration assay of MSCs. The expression of CXCL12 in the HPDLFs was much higher than that in HDFs in vitro. CXCL12 was localized in fibroblasts and extracellular matrix in the PDL in rats. Migration assay demonstrated that the number of migrated MSCs by HPDLFs was significantly higher than that by HDFs. In addition, the migrated MSCs also expressed CXCL12 and several genes that are familiar to fibroblasts. The results suggested that PDLFs are able to synthesize and secrete CXCL12 protein, and that CXCL12 induces migration of MSCs in the PDL in order to maintain rapid turnover of the PDL. The objective of this study was to investigate the function of CXCL12 in the PDL with rapid turnover.Microarray analysis was performed using a Whole Human Genome 8x60K (Agilent Technologies, Tokyo, Japan) containing approximately 44,000 transcripts. According to the manufacturerM-bM-^@M-^Ys protocol, total RNAs from HPDLFs and HDFs were labeled with Cy3 and hybridized on the microarray. The hybridization data for HPDLFs were compared with data for HDFs.

Differentially expressed long noncoding RNA expression between periodontal ligament stem cells from healthy periodontal tissue and periodontal ligament stem cells from inflammatory periodontal tissue.

Project description:Periodontitis can impair the osteogenic differentiation of human periodontal mesenchymal stem cells, but the underlying molecular mechanisms are still poorly understood. Long noncoding RNAs (lncRNAs) have been demonstrated to play significant roles under both physiologic and pathological conditions. We performed comprehensive lncRNAs profiling by lncRNA microarray to identify differentially expressed long noncoding RNA expression between Periodontal ligament stem cells from healthy Periodontal tissue and periodontal ligament stem cells from inflammatory periodontal tissue. Our analysis identified 233 lncRNAs and 423 mRNAs that were differently expressed (fold change >2.0, p-value < 0.05) between the two groups of cells. The GO analysis revealed that the significantly down-regulated biological processes included multicellular organismal process, developmental process and multicellular organismal development and the significantly up-regulated biological processes included cellular process, biological regulation and response to stimulus in periodontal ligament stem cells from inflammatory periodontal tissue. The Pathway analysis revealed that the differentially expressed mRNAs may involved in Focal adhesion, ECM-receptor interaction, Bacterial invasion of epithelial cells, Long-term depression, Circadian entrainment and HIF-1 signaling pathway. Two-condition experiment, periodontal ligament stem cells from healthy periodontal tissue (hPDLSCs) vs. periodontal ligament stem cells from inflammatory periodontal tissue (pPDLSCs), Biological replicates: 3 control replicates (hPDLSCs), 3 testing replicates (pPDLSCs).

Comparative gene expression analysis of the human periodontal ligament and dental pulp in the human permanent teeth

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.
