Neurofibroma is a tumor composed of a complex proliferation of neuromesenchymal tissue (Schwann cells, perineural cells, fibroblast, and mast cells). We report a 45-year-old female who had a slow growing, large, soft, pedunculated mass on her left lateral neck. A skin biopsy confirmed the diagnosis of neurofibroma.

The aim of this study was to test if an extremely weak 1 GHz electromagnetic field (EMF), known to be in resonance with clusters of water molecules, has biological effects on human fibroblasts. We demonstrated that in an in vitro model of wound healing, this EMF can activate fibroblast migration. [(3)H]thymidine incorporation experiments demonstrated that the EMF could also activate fibroblast ...

Background and objectives: Luteolin (3′,4′,5,7-tetrahydroxy flavone) is one of the most common flavones, which is naturally found in several edible plants and traditional medicine. It is known as a non-toxic compound with anti-inflammatory, antinociceptive, anticarcinogenic, antimutagenic, and antiangiogenic properties. Luteolin has antiproliferative activity against different ...

BACKGROUND There is a large increase in mast cell numbers in fibrotic lung tissue, suggesting that mast cells may play a part in the pathogenesis of pulmonary fibrosis. Glycosaminoglycans, such as heparan sulphate, that are structurally related to heparin (a mast cell product) are part of the extracellular matrix and known to regulate cell growth. Basic fibroblast growth factor is a heparin bin...

Fibroblast proliferation and migration play important roles in wound healing. bFGF is known to promote both fibroblast proliferation and migration during the process of wound healing. However, the signal transduction of bFGF-induced fibroblast migration is still unclear, because bFGF can affect both proliferation and migration. Herein, we investigated the effect of bFGF on fibroblast migration ...

BACKGROUND/AIMS The role of adventitial fibroblasts in the vascular inflammation observed in the adventitia of large vessels in numerous cardiovascular diseases remains unclear. Our objective was to explore the contribution of these cells to angiotensin II (Ang II)-induced aortic inflammation and adventitial expansion. METHODS Cytokine production by primary human aortic adventitial fibroblast...

As noted, the unrestrained accumulation of myofibroblasts is a key feature that differentiates fibrotic from physiologic repair. The accrual of these cells represents the combined effects of cell trafficking, proliferation and death. Of these, proliferation has received considerable attention; indeed, fibroblastic foci were initially defined as “small aggregates of actively proliferating fibrob...

Pulmonary fibrosis is characterized by lung fibroblast proliferation and collagen secretion. In lipopolysaccharide (LPS)-induced acute lung injury (ALI), aberrant proliferation of lung fibroblasts is initiated in early disease stages, but the underlying mechanism remains unknown. In this study, we knocked down Toll-like receptor 4 (TLR4) expression in cultured mouse lung fibroblasts using TLR4-...

AIMS AND BACKGROUND Human malignant melanoma is a very aggressive and highly angiogenesis-dependent tumor. Basic fibroblast growth factor and angiogenin are the potentially important angiogenic factors for melanoma progression and metastasis. Many studies have mainly focused on how they induce angiogenesis. In the present study, we investigated the effects of basic fibroblast growth factor on t...
