Introduction:  This study sought to assess the cytotoxic effects of nanoparticulate and microparticulate calcium sodium phosphosilicate mouthwashes on human gingival fibroblasts (HGFs). Methods: This in vitro study was conducted on HGFs isolated and cultured in a 48-well plate containing standard culture medium for evaluation of four concentrations of the two m...

Several recent studies have shown that proteins of the cadherin-catenin complex are not only involved in cell-cell adhesion but also in the proliferation and differentiation processes. For the first time, we investigated the effect of the quantity of cytoplasmic beta-catenin on dermal fibroblast proliferation by overexpressing human beta-catenin in human dermal fibroblasts. Our results show tha...

in this study, in vitro growth characteristics of fibroblasts of metacarpal region of horses and caspian miniature horses were evaluated. under general anesthesia and aseptic condition, a full thickness skin incision was created on the lateral aspect of mid-third of left metacarpal region of 4 mixed thoroughbred horses and 4 caspian miniature horses and 3 grams of subcutaneous tissue was harves...

Transforming growth factor-beta, a potent modulator of cell function, induces fibroblasts cultured on plastic to increase collagen synthesis. In 5- and 7-day porcine skin wounds, which have minimal to moderate collagen matrix, respectively, transforming growth factor-beta and type I procollagen were coordinately expressed throughout the granulation tissue. However, in 10-day collagen-rich granu...

Plasma and cell-derived fibronectin are potent chemoattractants for human dermal fibroblasts in vitro. The chemotactic property of fibronectin resides in a major 140,000-mol wt non-gelatin-binding fragment of the native molecule. Human monocytes and neutrophils do not recognize fibronectin as a chemotactic stimulus. These findings suggest that fibronectin and perhaps certain fragments of fibron...

BACKGROUND Angiotensin II (Ang II) has been implicated in the development of cardiac fibrosis. The aims of the present study were to examine expression and activity of ACE and of angiotensin receptors in human cardiac fibroblasts cultured from dilated cardiomyopathic and ischemic hearts. The effects of Ang II on fibroblasts were also investigated. METHODS AND RESULTS Human cardiac fibroblasts...

Toll-like receptors (TLRs) are known to recognize not only pathogen-associated molecular patterns but also danger-associated molecular patterns. Recent studies have characterized the expression levels and functions of TLRs in human epidermal cells. However, the characteristics of TLR family members in human dermal fibroblasts have not been thoroughly studied. Therefore, the present study system...

Cardiac fibrosis is a pathological process associated with the development of heart failure. TGF-? and WNT signaling have been implicated in pathogenesis cardiac fibrosis, however, little known about molecular cross-talk between these two pathways. The aim this study was to examine effect exogenous canonical WNT3a non-canonical WNT5a TGF-?-activated human fibroblasts. We found that induced ?-ca...
