Project description:Cementum protein 1 (CEMP1) is involved in cell adhesion, cell differentiation, regulates the mineralization processes during cementogenesis, and selects progenitor cells from periodontal ligament. To determine the gene expression profiling induced by CEMP1 overexpression by non-osteogenic cells such as human gingival fibroblasts we performed microarrays (Human Gene 1.0 ST, Affymetrix) to identify differentially expressed transcripts (ED) between human gingival fibroblasts (HGF) and those that overexpress CEMP1 (HGF/CEMP1).

Project description:Analysis of response to leptin and IL-1β in gingival fibroblasts at the gene expression level. The hypothesis tested in the present study was that leptin and IL-1β synergistically effect the phenotype of gingival fibroblasts. Results provide important information regarding the response of gingival fibroblasts to leptin and IL-1β, such as specific inflammatory genes that were up- or down-regulated.

Project description:The transcriptome of extracellular vesicles (EVs) from human gingival mesenchymal stem cells (GMSC) hasn't been compenhensively profiled. We performed the RNA-SEQ transcriptomic analysis of EVs from GMSC or Fibroblasts. Guman gingiva samples were collected following routine dental procedures. The primary cultured human dermal fibroblasts were used as a control since them share similar morphologies but lack the functional activities of GMSCs. Primary human dermal fibroblasts were isolated from the foreskin dermis of children aged between 6 and 8 years who underwent surgery.

HGF cells overexpressing CEMP1 and controls were harvested at 3, 7 and 14 days after transfection of CEMP1, three biological replicates were analyzed for each time point and condition for a total of 18 microarrays.

Project description:Fibroblasts are widely used cells for regenerative medicine in clinics, such as gingival or facial skin treatment. In fact, fibroblasts are considered as a mixture of various types of cells with "spindle shape" and there is no available clear marker. Gingival and dermal fibroblasts are similar in their morphology and function; however it is considered that the cultured cells retain their original characteristics depending on the origin, which may contribute to the differential therapeutic effects. For example, gingival wounds are known to heal relatively quickly with less scar formation compared with skin, which may imply their higher capability for regeneration as a therapeutic effect. The reason for this phenomenon may be partly due to characteristic differences between gingival and dermal fibroblasts including the expression of migration stimulating factor and matrix formation but these differences remain largely unknown. Recently, the characteristics of dermal fibroblasts have been reported to be different depending on body sites, such as face, trunk and plamoplantar skin. Although the expression of fibronectin and their splicing variants were known to be different between trunk and oral mucosal fibroblasts, there is still no detailed report on the functional differences between gingival and dermal fibroblasts. In this study, we investigated differential gene expression in normal gingival and dermal fibroblasts using DNA microarray to investigate the difference between the vague fibroblast-type cells from different tissue origin to achieve higher therapeutic effect in cell therapy.

In this study, we investigated differential gene expression in normal gingival and dermal fibroblasts using DNA microarray to investigate the difference between the vague fibroblast-type cells from different tissue origin to achieve higher therapeutic effect in cell therapy. Gingival and dermal tissues were collected from healthy patients. After successive stages primary culture and RNA extraction and hybridization on Affymetrix microarrays (Genome Focus Array). Dermal and gingival tissues were obtained from healthy volunteers (8 cases for dermal tissue; 6 females, 2 males , average age 48 and 8 cases for buccal gingival tissue; 6 females, 2 males, average age 43) whose informed consent was obtained according to a protocol approved by the ethics committee of Nagoya University Hospital. After enzymatic digestion, tissues were cultured in Dulbecco's modified Eagle's medium (DMEM) containing 10% fetal bovine serum at 37°C in the presence of 5% CO2 for about 4 weeks as reported previously. Total mRNAs were extracted from cells between passages 4-5 by Trizol reagent (Invitrogen, Carlsbad, CA, USA) and were applied to Human Focus Arrays (Affymetrix, Santa Clara, CA, USA) for microarray analysis according to the manufacturer's protocol (http://www.affymetrix.com/support/technical/manuals.affx). The gene expression data were analyzed by Arrayassist (Stratagene, La Jolla, CA, USA). Briefly, 8,500 probes on the array, normalization and scaling (MAS5), flag-positive gene selection, unpaired t-test, and CV selection (<20) resulted in 5,284 genes to analyze. GO (Gene ontology) analysis was performed using the software default settings to find the gene group related to the same category of biological function by searching common key terms that were reported for each gene.

Project description:Eight different human cancer cell lines were cocultured with human cancer associated fibroblasts (CAF) as spheroid cultures. In another setup UT-SCC-7 cutaneous squamous cell carcinoma cells, together with human skin fibroblasts (SFB) and UT-SCC-2 cells together with gingival fibroblasts (GFB) were cultured as spheroid cocultures. These spheroids were treated with PAD4 or with citrullination buffer only. All spheroids were hypotonically lysed, and the remaining insoluble material was digested to peptides and analysed by LC-MS/MS.
