Treponema denticola outer membrane enhances the phagocytosis of collagen-coated beads by gingival fibroblasts. (1/958)

Human gingival fibroblasts (HGFs) degrade collagen fibrils in physiological processes by phagocytosis. Since Treponema denticola outer membrane (OM) extract perturbs actin filaments, important structures in phagocytosis, we determined whether the OM affects collagen phagocytosis in vitro by HGFs. Phagocytosis was measured by flow cytometric assessment of internalized collagen-coated fluorescent latex beads. Confluent HGFs pretreated with T. denticola ATCC 35405 OM exhibited an increase in the percentage of collagen phagocytic cells (phagocytosis index [PI]) and in the number of beads per phagocytosing cell (phagocytic capacity [PC]) compared with untreated controls. The enhancement was swift (within 15 min) and was still evident after 1 day. PI and PC of HGFs for bovine serum albumin (BSA)-coated beads were also increased, indicating a global increase in phagocytic processes. These results contrasted those for control OM from Veillonella atypica ATCC 17744, which decreased phagocytosis. The T. denticola OM-induced increase in bead uptake was eliminated by heating the OM and by depolymerization of actin filaments by cytochalasin D treatment of HGFs. Fluid-phase accumulation of lucifer yellow was enhanced in a saturable, concentration-dependent, transient manner by the T. denticola OM. Our findings were not due to HGF detachment or cytotoxicity in response to the T. denticola OM treatment since the HGFs exhibited minimal detachment from the substratum; they did not take up propidium iodide; and there was no change in their size, granularity, or content of sub-G1 DNA. We conclude that a heat-sensitive component(s) in T. denticola OM extract stimulates collagen phagocytosis and other endocytic processes such as nonspecific phagocytosis and pinocytosis by HGFs.  (+info)

Lipoteichoic acid acts as an antagonist and an agonist of lipopolysaccharide on human gingival fibroblasts and monocytes in a CD14-dependent manner. (2/958)

CD14 has been implicated as a receptor of lipoteichoic acid (LTA) and other bacterial components as well as lipopolysaccharide (LPS). Since the structures of LTAs from various gram-positive bacteria are heterogeneous, we analyzed the effects of LTAs on the secretion of interleukin-8 (IL-8) by high- and low-CD14-expressing (CD14(high) and CD14(low)) human gingival fibroblasts (HGF). While Bacillus subtilis LTA had an IL-8-inducing effect on CD14(high) HGF which was considerably weaker than that of LPS, Streptococcus sanguis and Streptococcus mutans LTAs had practically no effect on the cells. B. subtilis LTA had only a weak effect on CD14(low) HGF, as did LPS. S. sanguis and S. mutans LTAs at a 1,000-fold excess each completely inhibited the IL-8-inducing activities of both LPS and a synthetic lipid A on CD14(high) HGF. The effect of LPS was also inhibited by the presence of an LPS antagonist, synthetic lipid A precursor IVA (LA-14-PP), with a 100-fold higher potency than S. sanguis and S. mutans LTAs and by anti-CD14 monoclonal antibody (MAb). S. sanguis and S. mutans LTAs, LA-14-PP, and anti-CD14 MAb had no significant effect on phorbol myristate acetate-stimulated IL-8 secretion by HGF. These LTAs also inhibited the IL-8-inducing activity of B. subtilis LTA on CD14(high) HGF, as did LA-14-PP and anti-CD14 MAb. The antagonistic and agonistic functions of LTAs were also observed with human monocytes. Binding of fluorolabeled LPS to human monocytes was inhibited by S. sanguis LTA, although the inhibition was 100 times weaker than that of LPS itself, and anti-CD14 MAb inhibited fluorolabeled LPS and S. sanguis LTA binding. Binding of LTAs to CD14 was also observed with nondenaturing polyacrylamide gel electrophoresis. These results indicate that LTAs act as antagonists or agonists via a CD14-dependent mechanism, probably due to the heterogeneous structure of LTAs, and that an antagonistic LTA might be a useful agent for suppressing the periodontal disease caused by gram-negative bacteria.  (+info)

Targeted disruption of fibronectin-integrin interactions in human gingival fibroblasts by the RI protease of Porphyromonas gingivalis W50. (3/958)

Cell surface integrins mediate interactions between cells and their extracellular matrix and are frequently exploited by a range of bacterial pathogens to facilitate adherence and/or invasion. In this study we examined the effects of Porphyromonas gingivalis proteases on human gingival fibroblast (HGF) integrins and their fibronectin matrix. Culture supernatant from the virulent strain W50 caused considerably greater loss of the beta1 integrin subunit from HGF in vitro than did that of the beige-pigmented strain W50/BE1. Prior treatment of the W50 culture supernatant with the protease inhibitor Nalpha-p-tosyl-L-lysine chloromethyl ketone (TLCK) blocked its effects on cultured cells, indicating that this process is proteolytically mediated. Purified arginine-specific proteases from P. gingivalis W50 were able to mimic the effects of the whole-culture supernatant on loss of beta1 integrin expression. However purified RI, an alpha/beta heterodimer in which the catalytic chain is associated with an adhesin chain, was 12 times more active than RIA, the catalytic monomer, in causing loss of the alpha5beta1 integrin (fibronectin receptor) from HGF. No effect was observed on the alphaVbeta3 integrin (vitronectin receptor). The sites of action of RI and RIA were investigated in cells exposed to proteases pretreated with TLCK to inactivate the catalytic component. Use of both monoclonal antibody 1A1, which recognizes only the adhesin chain of RI, and a rabbit antibody against P. gingivalis whole cells indicated localization of RI on the fibroblasts in a clear, linear pattern typical of that seen with fibronectin and alpha5beta1 integrin. Exact colocalization of RI with fibronectin and its alpha5beta1 receptor was confirmed by double labeling and multiple-exposure photomicroscopy. In contrast, RIA bound to fibroblasts in a weak, patchy manner, showing only fine linear or granular staining. It is concluded that the adhesin component of RI targets the P. gingivalis arginine-protease to sites of fibronectin deposition on HGF, contributing to the rapid loss of both fibronectin and its main alpha5beta1 integrin receptor. Given the importance of integrin-ligand interactions in fibroblast function, their targeted disruption by RI may represent a novel mechanism of damage in periodontal disease.  (+info)

The potential role of chemokines and inflammatory cytokines in periodontal disease progression. (4/958)

Inflammation is regulated by the expression of mediators that cause a number of pleiotropic events culminating in the recruitment of inflammatory cells and release of biologic mediators by leukocytes. If the inflammation is transient in nature, it can protect the host by activating defense mechanisms and initiating wound repair. However, if the inflammation is inappropriate, it can lead to considerable tissue damage. My colleagues and I have investigated the role of chemokines, particularly monocyte chemoattractant protein 1, in various pathological processes and the role of the proinflammatory cytokines interleukin-1 (IL-1) and tumor necrosis factor (TNF) in experimental periodontitis. I will discuss first the studies on chemokines and then the use of IL-1 and TNF blockers in inhibiting inflammation and bone loss in the periodontium.  (+info)

Induction of prostaglandin release from macrophages by bacterial endotoxin. (5/958)

This review summarizes the role of the monocytic responses to lipopolysaccharide as it relates to periodontal disease severity. Data are presented which illustrate that the levels of prostaglandin E2 (PGE2) secreted by systemic peripheral blood monocytes in culture, in the presence of bacterial endotoxins, are highly correlated with the levels observed in the gingival crevicular fluid. Furthermore, the different periodontal diagnostic categories have varying levels of monocytic and crevicular fluid PGE2, in juxtaposition with clinical disease severity. These data are consistent with the concept that there is close synchrony between the systemic responsiveness of peripheral blood monocytes with regard to prostanoid synthesis and the local levels of mediator present within the gingival crevice.  (+info)

Production of beta-defensin antimicrobial peptides by the oral mucosa and salivary glands. (6/958)

beta-Defensins are cationic peptides with broad-spectrum antimicrobial activity that are produced by epithelia at mucosal surfaces. Two human beta-defensins, HBD-1 and HBD-2, were discovered in 1995 and 1997, respectively. However, little is known about the expression of HBD-1 or HBD-2 in tissues of the oral cavity and whether these proteins are secreted. In this study, we characterized the expression of HBD-1 and HBD-2 mRNAs within the major salivary glands, tongue, gingiva, and buccal mucosa and detected beta-defensin peptides in salivary secretions. Defensin mRNA expression was quantitated by RNase protection assays. HBD-1 mRNA expression was detected in the gingiva, parotid gland, buccal mucosa, and tongue. Expression of HBD-2 mRNA was detected only in the gingival mucosa and was most abundant in tissues with associated inflammation. To test whether beta-defensin expression was inducible, gingival keratinocyte cell cultures were treated with interleukin-1beta (IL-1beta) or bacterial lipopolysaccharide (LPS) for 24 h. HBD-2 expression increased approximately 16-fold with IL-1beta treatment and approximately 5-fold in the presence of LPS. Western immunoblotting, liquid chromatography, and mass spectrometry were used to identify the HBD-1 and HBD-2 peptides in human saliva. Human beta-defensins are expressed in oral tissues, and the proteins are secreted in saliva; HBD-1 expression was constitutive, while HBD-2 expression was induced by IL-1beta and LPS. Human beta-defensins may play an important role in the innate defenses against oral microorganisms.  (+info)

Transcriptional activation of mRNA of intercellular adhesion molecule 1 and induction of its cell surface expression in normal human gingival fibroblasts by Mycoplasma salivarium and Mycoplasma fermentans. (7/958)

Lipoproteins in the cell membranes of both Mycoplasma salivarium and Mycoplasma fermentans were demonstrated to trigger the transcription of intercellular adhesion molecule-1 mRNA in normal fibroblasts isolated from human gingival tissue and to induce its cell surface expression by a mechanism distinct from that of Escherichia coli lipopolysaccharide. The lipid moiety of the lipoproteins was suggested to play a key role in the expression of the activity.  (+info)

Overgrowth of oral mucosa and facial skin, a novel feature of aspartylglucosaminuria. (8/958)

Aspartylglucosaminuria (AGU) is a lysosomal storage disorder caused by deficiency of aspartylglucosaminidase (AGA). The main symptom is progressive mental retardation. A spectrum of different mutations has been reported in this disease, one missense mutation (Cys163Ser) being responsible for the majority of Finnish cases. We were able to examine 66 Finnish AGU patients for changes in the oral mucosa and 44 of these for changes in facial skin. Biopsy specimens of 16 oral lesions, 12 of them associated with the teeth, plus two facial lesions were studied histologically. Immunohistochemical staining for AGA was performed on 15 oral specimens. Skin was seborrhoeic in adolescent and adult patients, with erythema of the facial skin already common in childhood. Of 44 patients, nine (20%) had facial angiofibromas, tumours primarily occurring in association with tuberous sclerosis. Oedemic buccal mucosa (leucoedema) and gingival overgrowths were more frequent in AGU patients than in controls (p<0.001). Of 16 oral mucosal lesions studied histologically, 15 represented fibroepithelial or epithelial hyperplasias and were reactive in nature. Cytoplasmic vacuolisation was evident in four. Immunohistochemically, expression of AGA in AGU patients' mucosal lesions did not differ from that seen in corresponding lesions of normal subjects. Thus, the high frequency of mucosal overgrowth in AGU patients does not appear to be directly associated with lysosomal storage or with alterations in the level of AGA expression.  (+info)

Porphyromonas gingivalis is the foremost oral pathogen of adult periodontitis in humans. However, the mechanisms of bacterial invasion and the resultant destruction of the gingival tissue remain largely undefined. We report host-P. gingivalis interactions in primary human gingival fibroblast (HGF) cells. Quantitative immunostaining revealed the need for a high multiplicity of infection for optimal infection. Early in infection (2-12 h), P. gingivalis activated the proinflammatory transcription factor NF-kappa B, partly via the PI3 kinase/AKT pathway. This was accompanied by the induction of cellular anti-apoptotic genes, including Bfl-1, Boo, Bcl-XL, Bcl2, Mcl-1, Bcl-w and Survivin. Late in infection (24-36 h) the anti-apoptotic genes largely shut down and the pro-apoptotic genes, including Nip3, Hrk, Bak, Bik, Bok, Bax, Bad, Bim and Moap-1, were activated. Apoptosis was characterized by nuclear DNA degradation and activation of caspases-3, -6, -7 and -9 via the intrinsic mitochondrial pathway. Use of

BACKGROUND AND AIM: An important goal of periodontal plastic surgery is the creation of attached gingiva around the teeth. In this study, the aims were to culture gingival fibroblasts in a biodegradable scaffold and measure the width of attached gingiva after the clinical procedure.METHODS: This study was carried out on 4 patients (8 sites), with inadequate attached gingiva next to at least two teeth in contralateral quadrants of the same jaw. A biopsy of attached gingiva (epithelial + connective tissue) was taken using a surgical blade. Following culture of gingival fibroblasts, 250 × 103 cells in 250 µl nutritional medium were mixed with platelet-rich in growth factor (PRGF). Periosteal fenestration technique was done on one side (control) and tissue-engineered mucosal graft (test) was carried out on the contralateral side in each patient. The width of keratinized tissue, probing depth (PD) and width of attached gingiva were recorded at baseline and 3 months after the operation.RESULTS: An increased

Alpha-melanocyte stimulating hormone (α-MSH) is involved in normal skin wound healing and also has anti-inflammatory properties. The association of α-MSH to polyelectrolyte layers with various supports has been shown to improve these anti-inflammatory properties. This study aimed to evaluate the effects of nanofibrous membrane functionalized with α-MSH linked to polyelectrolyte layers on gingival cell inflammatory response. Human oral epithelial cells (EC) and fibroblasts (FB) were cultured on plastic or electrospun Poly-#-caprolactone (PCL) membranes with α-MSH covalently coupled to Poly-L-glutamic acid (PGA-α-MSH), for 6 to 24 h. Cells were incubated with or without Porphyromonas gingivalis lipopolysaccharide (Pg-LPS). Cell proliferation and migration were determined using AlamarBlue test and scratch assay. Expression of interleukin-6 (IL-6), tumor necrosis factor (TNF-α), and transforming growth factor-beta (TGF-β) was evaluated using RT-qPCR method. Cell cultures on plastic showed that PGA-α
Irsogladine maleate (IM) counters Aggregatibacter actinomycetemcomitans-induced reduction of the gap junction intercellular communication and the expression of zonula occludens-1, which is a major tight junction structured protein, in cultured human gingival epithelial cells (HGEC). In addition, IM obviates the A. actinomycetemcomitans-induced increase in interleukin (IL)-8 levels in HGEC. Thus, by regulating the intercellular junctional complex and chemokine secretion in HGEC, IM may be useful to prevent periodontal disease. To clarify the effects and regulatory mechanism of IM in vivo and in vitro, we examined the expression of E-cadherin and neutrophil chemotaxis induced by A. actinomycetemcomitans under IM pretreatment. Immunohistochemical studies revealed that A. actinomycetemcomitans application to the gingival sulcus decreased the number of cells positive for E-cadherin and increased those positive for cytokine-induced neutrophil chemoattractant-2α (CINC-2α) in rat gingival epithelium ...

DOI: 10.11607/prd.00.0824 Cultured gingival dermal substitute (CGDS), composed of gingival fibroblasts and matrix and fabricated using tissue-engineering techniques, has been used for root coverage procedures. Fourteen sites from four patients with ≥ 2 mm of Miller Class I or II facial gingival tissue recession were treated. The autologous CGDS sheet, prepared prior to surgical treatment, was grafted over the teeth with gingival recession and then covered with a coronally positioned flap. Vertical and horizontal recession was measured at baseline (prior to the surgical procedure) and 13 to 40 weeks (average: 30.7 9.6 weeks) after surgery. The average vertical and horizontal root coverage after surgery was 79.1% 25.7% and 75.2% 31.4%, respectively. Moreover, there was a significant increase of keratinized and attached gingival tissue at the final clinical evaluation compared with preoperative measurements (P < .05). These results demonstrate CGDS as a promising grafting material for use with ...
Wound healing is a dynamic process that involves highly coordinated cellular events, including proliferation and migration. Oral gingival fibroblasts serve a central role in maintaining oral mucosa homeostasis, and their functions include the coordination of physiological tissue repair. Recently, surface pre‑reacted glass‑ionomer (S‑PRG) fillers have been widely applied in the field of dental materials for the prevention of dental caries, due to an excellent ability to release fluoride (F). In addition to F, S‑PRG fillers are known to release several types of ions, including aluminum (Al), boron (B), sodium (Na), silicon (Si) and strontium (Sr). However, the influence of these ions on gingival fibroblasts remains unknown. The aim of the present study was to examine the effect of various concentrations of an S‑PRG filler eluate on the growth and migration of gingival fibroblasts. The human gingival fibroblast cell line HGF‑1 was treated with various dilutions of an eluent solution of ...

Several grafting techniques and guided tissue regeneration techniques (GTR) have been well-developed in periodontal surgery. However, these techniques could induce pain and side effects, such as a gingival recession during the healing period following the therapy. The graft of a small autologous connective tissue, using non-invasive surgical techniques could yield several benefits for the patients. Our preliminary study explores the feasibility of collecting healthy gingival tissues, culturing them in vitro to amplify rat gingival fibroblasts (RGF) and inoculating the obtained cells into autologous rat gingival tissues in vivo. Gingival tissues samples were cultured as explants as described by Freshney et al. and Adolphe. ...
Objective: To investigate the contribution of cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) to PGE2 production in human gingival fibroblast cells stimulated with lipopolysaccharide from periodontopathogenic bacteria. Methods: Lipopolysaccharide was isolated from Porphyromonas gingivalis and Prevotella intermedia by the phenol-water method. Human gingival fibroblast cells were stimulated with lipopolysaccharide in different concentration for different time periods. The levels of PGE2 in the culture medium were measured by radioimmunoassay. The expression of COX-2 protein was observed by immunocytochemical staining; COX-1 and COX-2 mRNA expression were examined by semi-quantitative RT-PCR analysis. Results: The production of PGE2 in human gingival fibroblast cells was increased in a time- and dose-dependent manner (P < .01, P < .01). Immunocytochemical staining showed the positive expression of COX-2 protein in stimulated cells around the unstained cell nucleus, while no expression was ...

AU - Yatani, H.. AU - Egusa, H.. PY - 2016/1/1. Y1 - 2016/1/1. N2 - Human gingival fibroblasts (hGFs) present an attractive source of induced pluripotent stem cells (iPSCs), which are expected to be a powerful tool for regenerative dentistry. However, problems to be addressed prior to clinical application include the use of animal-derived feeder cells for cultures. The aim of this study was to establish an autologous hGF-derived iPSC (hGF-iPSC) culture system by evaluating the feeder ability of hGFs. In both serum-containing and serum-free media, hGFs showed higher proliferation than human dermal fibroblasts (hDFs). Three hGF strains were isolated under serum-free conditions, although 2 showed impaired proliferation. When hGF-iPSCs were transferred onto mitomycin C-inactivated hGFs, hDFs, or mouse-derived SNL ...

Objective: Several local factors can affect the wound-healing process, delaying its progression and postponing tissue homeostasis. It is known that local inflammation is related to wound healing; however, the maintenance of the inflammatory reaction can impair the proliferation and migration of oral mucosal cells. The aim of this study was to evaluate the viability and chemokine expression of epithelial cells and gingival fibroblasts exposed to long-term lipopolysaccharide (LPS) treatment. Design: Epithelial cells (HaCaT, Cell Lines Service, 300493) and human gingival fibroblasts (HGFs) were seeded (1 105 cells/well) in 24-well plates and incubated for 24 h. To simulate the responses of cells to a local chronic oral mucosal inflammation, we added LPS of Escherichia coli (10 mg/ml) to Dulbeccos modified Eagles medium (DMEM), kept in contact with fibroblasts and epithelial cells for 24, 48, and 72 h. Then the cells were assessed for viability (alamarBlue assay), number (trypan blue assay), and ...
Periodontitis is a chronic inflammatory disease affecting the soft tissue and bone that surrounds the teeth. Despite extensive research, distinctive genes responsible for the disease have not been identified. The objective of this study was to elucidate transcriptome changes in periodontitis, by investigating gene expression profiles in gingival tissue obtained from periodontitis-affected and healthy gingiva from the same patient, using RNA-sequencing. Gingival biopsies were obtained from a disease-affected and a healthy site from each of 10 individuals diagnosed with periodontitis. Enrichment analysis performed among uniquely expressed genes for the periodontitis-affected and healthy tissues revealed several regulated pathways indicative of inflammation for the periodontitis-affected condition. Hierarchical clustering of the sequenced biopsies demonstrated clustering according to the degree of inflammation, as observed histologically in the biopsies, rather than clustering at the individual ...
Epithelial mesenchymal transition (EMT) has been implicated in neoplastic invasion and metastasis. We have previously generated six cell lines from human gingival mucosal keratinocytes immortalized by E6/E7 of human papillomavirus type 16. Ldk and NuB1 lines represented EMT phenotype and other four lines represented cobblestone non-EMT phenotype. These cell lines were utilized as model cells to determine whether inhibitors of apoptosis proteins and cell-cycle regulators were molecular players during EMT. EMT cells exhibited increased expression of vimentin, vascular endothelial growth factor (VEGF) receptor1 and the ability to form tubules on Matrigel as well as to grow anchorage independently. We found that EMT cells expressed significantly elevated levels of cIAP-1, Bclx and p27 kip higher than non-EMT cells. These proteins could therefore be used as intrinsic indicators of EMT of human gingival keratinocytes. © 2009 John Wiley & Sons A/S ...

Direct bonding of orthodontic brackets is an established procedure and has lead to increasing number of light-cured bonding materials produced with ever-increasing bond strength and ease of delivery. However, considerably less attention is given to biocompatibility of these materials. Both in vivo and in vitro studies indicate orthodontic bonding agents are cytotoxic. Spectrophotometric analysis revealed that these resins contained a great amount of potentially toxic, leachable, un-polymerized material, even when fully cured. Hypothesis: Different light-cured bonding agents may have different cytotoxic effects depending on their chemistry. Objective: Compare and analyze the toxicity of three different light-cured bonding agents to a population of gingival cells as measured by cell growth, and viability in vitro. Method: Light Bond®, MonoLok®, and Transbond XT® orthodontic adhesives were tested. Human gingival cells were obtained from extracted third molars, pooled, and expanded until needed. ...

We chose cattle gingival epithelium to have a readily available supply of tissues. In this study we investigated the normal levels of some enzymes involved in glucose metabolism within bovine attached gingival epithelium. In determining the relative levels of the enzyme in any particular series of metabolic pathways, it is emphasized that we are only reporting the potential for conversion of substrate to product. The existence of these ...
Dental professionals are well positioned to educate patients about the overall health implications of chronic inflammation, particularly relating to periodontal disease. A greater understanding of the role of inflammation in various seemingly unrelated conditions allows practitioners to provide alternative strategies for prevention while resolving inflammation to reduce the risk of various systemic conditions.2. Periodontitis occurs when bacteria trigger inflammation with the release of various biochemical mediators, such as cytokines, which may lead to the destruction of gingival connective tissue and bone.3 Chronic adult periodontitis is the common form of this bacterially induced inflammatory disease, which affects a substantial number of adults and has shown to be a significant contributing factor to other systemic conditions.4 Chronic diseases such as atherosclerotic cardiovascular disease, rheumatoid arthritis, and diabetes mellitus may develop or worsen in part due to uncontrolled ...

The keratinized oral gingival epithelium provides effective protection against both mechanical trauma and bacterial invasion. The horny cell layer acts like a film of plastic wrap, allowing the body to retain moisture and protecting it from invasion by foreign substances and comprises various substances such as keratins, produced by the epidermal keratinocytes and lipids. The epidermal keratinocytes divide in the basal layer, produce keratins and differentiate, and migrate to the upper layers as they mature by a process called keratinization. The present review discusses the structure of keratin, the process of keratinization and their distribution in gingival epithelium.. ...

AU - Kanaya, Sousuke. AU - Shimonishi, Mitsuru. AU - Shimauchi, Hidetoshi. PY - 2014/10/1. Y1 - 2014/10/1. N2 - Background: Dental calculus is calcified plaque composed primarily of calcium phosphate mineral salts, and there is a clear association between the presence of calculus and the initiation/progression of periodontitis. However, it is still inconclusive whether dental calculus can be a direct causative factor. The authors examined the effect of nano/microsized calcium phosphate particles, which may be generated in the process of early precipitation and/or dissolution of calcium phosphate mineral, on the expression of interleukin (IL)-8 in human gingival epithelial cells. Methods: Primary human gingival epithelial cells and/or a human gingival carcinoma cell line (Ca9-22) were stimulated with ...
TY - JOUR. T1 - Human gingival fibroblast feeder cells promote maturation of induced pluripotent stem cells into cardiomyocytes. AU - Matsuda, Yusuke. AU - Takahashi, Ken. AU - Kamioka, Hiroshi. AU - Naruse, Keiji. PY - 2018/9/10. Y1 - 2018/9/10. N2 - The use of human induced pluripotent stem (iPS) cells has been investigated in multiple regenerative medicine studies. However, although methods for efficient differentiation of iPS cells into heart tissues have been devised, it remains difficult to obtain cardiac tissue with high contractility. Herein, we established a method for differentiating iPS cells into highly contractile cardiomyocytes (CMs), and demonstrate that the use of human gingival fibroblasts (HGFs) as a feeder cells promotes maturation of iPS-derived CMs (iPS-CMs) in vitro. After CM differentiation of iPS cells, iPS-CMs showed increased mRNA expression of the CM specific maker cardiac troponin T (cTnT) in the absence and presence (on-feeder condition) of cocultured HGFs, and ...
Shikonin, an active ingredient of Lithospermum erythrorhizon, exerts anti-inflammatory and antibacterial effects, and promotes wound healing. We investigated whether shikonin stimulated gingival tissue wound healing in human gingival fibroblasts (hGF). In addition, we evaluated the effects of shikonin on the mitogen-activated protein kinase (MAPK) signaling pathway, which has an important role in wound healing. hGF were subjected to primary culture using gingiva collected from patients. The cells were exposed to/treated with Shikonin at concentrations ranging from 0.01 to 100 μM. The optimal concentration was determined by cell proliferation and migration assays. Type I collagen and fibronectin synthesis, the gene expression of vascular endothelial growth factor (VEGF) and FN, and the phosphorylation of Extracellular signal-regulated kinase (ERK) 1/2 were investigated. Identical experiments were performed in the presence of PD98059 our data suggest, a specific ERK 1/2 inhibitor. Shikonin

Porphyromonas gingivalis, a periodontal pathogen, can invade primary cultures of gingival epithelial cells. Optimal invasion occurred at a relatively low multiplicity of infection (i.e., 100) and demonstrated saturation at a higher multiplicity of infection. Following the lag phase, during which bacteria invaded poorly, invasion was independent of growth phase. P. gingivalis was capable of replicating within the epithelial cells. Invasion was an active process requiring both bacterial and epithelial cell energy production. Invasion was sensitive to inhibitors of microfilaments and microtubules, demonstrating that epithelial cell cytoskeletal rearrangements are involved in bacterial entry. P. gingivalis, but not epithelial cell, protein synthesis was necessary for invasion. Invasion within the epithelial cells was not blocked by inhibitors of protein kinase activity. Invasion was inhibited by protease inhibitors, suggesting that P. gingivalis proteases may be involved in the invasion process. ...
OBJECTIVES The purpose of the present study was to analyse transcriptomes and mRNA expression levels for specific genes in calcium-channel blocker-induced gingival overgrowth (GO) tissues. DESIGN Eight gingival tissues samples (from both GO negative and positive sites) were harvested from four GO patients for microarray analyses. Twelve candidate genes were selected for further quantitative real time reverse transcription-polymerase chain reaction (qRT-PCR) analyses. Ten GO tissues from periodontitis patients and ten control gingival tissues from healthy subjects were compared by qRT-PCR. Mann-Whitney U-test was used for statistical evaluation. RESULTS In GO positive tissues, 163-1631 up-regulated and 100-695 down-regulated genes were identified with more than two-fold changes compared with GO negative tissues amongst patients by microarray experiments. No commonly expressed genes amongst the eight sets of microarray data were found. The clustering analysis confirmed that the entire transcriptome
Monkey periodontal ligament fibroblasts (MPLF cells), human gingival fibroblasts (HGF cells), rat embryonic calvaria cells (REC cells), porcine periodontal ligament epithelial cells (PPLE cells) and rat osteosarcoma 17/2 cells (ROS cells) were incorporated into 3-dimensional collagen gels plated in 60 mm Petri dishes in order: first, to measure the capacity of these cell types to contract; second, to investigate cell-collagen and intercellular relationships during contraction; and third, to define the cellular contribution to tissue contraction in an in vitro system. Measurements at times up to 72 h on 3 ml gels containing 5 × 10(5) cells and with a collagen concentration of 1.20 mg/ml showed that MPLF cells contracted the gels at a significantly greater rate (P less than 0.001) than did the other cell types. In addition, contraction started sooner and was of greater extent than with the other cells. HGF cells contracted the gels more rapidly than REC and PPLE cells, while ROS cells caused no ...
Background: Root surface debridement (RSD) is necessary to create an environment suitable for reattachment of the periodontium. Root surface conditioning may aid the formation of a biocompatible surface suitable for cell reattachment. BioPure™ MTAD (mixture of Doxycycline, citric acid and a detergent) is an endodontic irrigant with antibacterial properties and the ability to remove smear layer. It was hypothesized that MTAD may be useful for root surface conditioning. The efficacy of MTAD as a conditioner was measured by examining fibroblast attachment to root surfaces. Materials and Methods: Thirty-two specimens of human teeth with advanced periodontal disease were used. The surfaces were root planed until smooth. Half of the specimens were treated with 0.9% saline and the other samples with Biopure MTAD. As a negative control group, five further samples were left unscaled with surface calculus. Human gingival fibroblast cells HGF1-PI1 were cultured and poured over the tooth specimens and ...
The etiopathogenesis of periodontal disease results from complex interaction between infectious agents, mainly including bacteria, and host cellular and humoral immune responses. However it is thought that bacteria-induced pathogenesis is not sufficient alone to explain all biological and clinical features of the destructive periodontal disease. The main hypothesis is that herpesviruses, such as Epstein-Barr Virus, may participate as well by altering epithelial gingival cell biology and consequently may promote the initiation and progression of periodontitis ...

Arlington Heights oral surgeon, Dr. Khan recommends gingival graft if a build-up of calculus and plaque on the root or if tooth decay has already started.
In the most drastic stage of periodontal disease, the bone and the attachment of the gums to the teeth have been destroyed. This may cause your teeth to shift or loosen and can affect how your teeth come together. You may notice a bad taste or smell in your mouth. Proper dental care must be initiated to save the teeth or they may need to be removed. Professional intervention may involve pocket reduction therapy and bone grafting along with the incorporation of other therapies.. Pocket reduction therapy is required for this form of periodontal disease when the gingival tissues have not resolved after initial treatment or tissue and root therapy. This is usually necessary when gingival tissues have not shrunk enough or when the supporting bone around the teeth has been lost. Since the gum tissue has not shrunk, they provide a greater place for bacteria to live and attack the bone and tissue causing further damage to occur.. Pocket reduction is a periodontal disease therapy that turns or pulls back ...
Periodontitis is a chronic destructive category of periodontal disease that progresses to the resorption of alveolar bone, which leads to progressive bone destruction and tooth loss. As a consequence of resorption, breakdown of products are released into periodontal tissues, migrating toward the gingival sulcus and gathering from the surrounding site in whole saliva, where several of them have been identified. 2930. Among the several host enzymes proposed as diagnostic indicators of periodontal status, ALP was one of the first to be identified. 31 ALP is released from polymorphonuclear cells (PMNs) during inflammation 10 and from osteoblasts 32 and periodontal ligament fibroblasts 33 during bone formation and periodontal regeneration respectively.. ALP activity in serum has been extensively studied, and it was suggested that ALP allows bone mineralization by releasing an organic phosphate that contributes to the deposition of calcium phosphate complexes into the osteoid matrix. 3435 ALP might ...

Periodontal disease occurs when bacteria from the mouth form on the pets teeth in a substance called plaque. The plaque makes its way under the gumline and sets in motion a vicious circle, which can eventually lead to tooth loss for the animal. The bacteria in the subgingival plaque will secrete toxins. These toxins damage the periodontal tissues and can decrease the attachment.. However, the bacteria will also elicit an inflammatory response from the animals gingival tissues. White blood cells and other inflammatory mediators will leak out of the periodontal tissues and into the periodontal space (between the gum or bone and the tooth). The white blood cells will release their enzymes to destroy the bacterial invaders, but will also damage the attachment of the tooth. As this progresses, the pocket will get deeper and deeper. This will weaken the bone in the area, and if it is in the lower jaw it can weaken it to the point of causing a pathologic fracture. This is most common in older small ...

Periodontitis, an inflammatory disease that affects the tissues surrounding the teeth, is a common disease worldwide. It is caused by a dysregulation of the host inflammatory response to bacterial infection, which leads to soft and hard tissue destruction. In particular, it is the excessive inflammation in response to bacterial plaque that leads to the release of reactive oxygen species (ROS) from neutrophils, which, then play a critical role in the destruction of periodontal tissue.Generally, ROS produced from immune cells exhibit an anti-bacterial effect and play a role in host defense and immune regulation. Excessive ROS, however, can exert cytotoxic effects, cause oxidative damage to proteins and DNA, can interfere with cell growth and cell cycle progression, and induce apoptosis of gingival fibroblasts. Collectively, these effects enable ROS to directly induce periodontal tissue damage. Some ROS also act as intracellular signaling molecules during osteoclastogenesis, and can thus also play an
