conclusions based on the results of the current study, it was concluded that aloe vera, licorice and mint extracts had synergistic effects on the viability of dermal fibroblasts; in addition, the combination of aloe vera and licorice with either henna or myrtle, and aloe vera and mint with either cedar or ginger resulted in synergistic effects on viability of dermal fibroblasts. the third categ...

context connective tissue cells include fibroblasts, chondrocytes, adipocyte, and osteocytes. these cells are specialized for the secretion of collagenous extracellular matrix and are responsible for the architectural framework of the human body. evidence acquisition connective tissue cells play a central role in supporting as well as repairing tissues and organs. fibroblast cell therapy could ...

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...

INTRODUCTION Increased levels of genes in the type I interferon (IFN) pathway have been observed in patients with systemic sclerosis (SSc), or scleroderma. How type I IFN regulates the dermal fibroblast and its participation in the development of dermal fibrosis is not known. We hypothesized that one mechanism by which type I IFN may contribute to dermal fibrosis is through upregulation of spec...

Gamma-glutamyl carboxylase (GGCX) gene mutation causes GGCX syndrome (OMIM: 137167), which is characterized by pseudoxanthoma elasticum (PXE)-like symptoms and coagulation impairment. Here, we present a 55-year-old male with a novel homozygous deletion mutation, c.2,221delT, p.S741LfsX100, in the GGCX gene. Histopathological examination revealed calcium deposits in elastic fibers and vessel wal...

Dermal fibroblasts produce a collagen-rich extracellular matrix, which confers mechanical strength and resiliency to human skin. During aging, collagen production is reduced and collagen fragmentation is increased, which is initiated by matrix metalloproteinase-1 (MMP-1). This aberrant collagen homeostasis results in net collagen deficiency, which impairs the structural integrity and function o...

Human induced pluripotent stem cells (hiPSC) line FLENIi001-A was reprogrammed from dermal fibroblasts using the lentiviral-hSTEMCCA-loxP vector. Fibroblasts were obtained a skin biopsy of 72-year-old Caucasian male familial Alzheimer's disease patient carrying T119I mutation in PSEN1 gene. genotype maintained and stemness pluripotency confirmed hiPSC line.

The objective was to study Dupuytren's myofibroblast cells in constrained collagen matrices in order to more closely emulate their in vivo environment and, to correlate their contractility with alpha-smooth muscle actin (alpha-SMA) expression and determine if dermal fibroblasts regulate Dupuytren's myofibroblast phenotype. Isotonic and isometric force contraction by cells isolated from Dupuytre...

Stromal fibroblasts are an integral part of the tumor stroma and constantly interact with cancer cells to promote their initiation and progression. However, the role and function of dermal fibroblasts during the early stage of melanoma development remain poorly understood. We, therefore, designed a novel genetic approach to deactivate stromal fibroblasts at the onset of melanoma formation by ta...

BACKGROUND Dermal fibroblasts from patients with systemic sclerosis (SSc) release excessive amounts of collagen resulting in tissue fibrosis. The molecular mechanisms underlying this pathological activation are incompletely understood. OBJECTIVE To investigate whether Notch signalling contributes to the uncontrolled activation of fibroblasts in SSc. METHODS Activation of the Notch pathway w...
