background: the multifunctional transforming growth factor beta (tgf-β) is a glycoprotein that exists in three isoforms. tgf-β3 expression increases in fetal wound healing and reduces fibronectin and collagen i and iii deposition, and also improves the architecture of the neodermis which is a combination of blood vessels and connective tissue during wound healing. fibroblasts are key cells in t...
Background: Lymph node stromal fibroblasts are interconnected with TCD4+ cells and affect their phenotype and function. Understanding the nature of these interactions under unusual conditions like infections will help to their application in control and regulation of immune responses. Materials and methods: Lymph node fibroblasts were affected in BCG primed immune environment by both in-...
Introduction: Ameloblastoma is a benign odontogenic neoplasm with a high risk of recurrence. Ameloblastoma stromal fibroblasts are associated with tumor growth and invasion; however, a few studies have evaluated the immunohistochemical characteristics of stromal fibroblasts and their association with recurrence in Ameloblastoma. Galectin-3 (gal-3) is a member of the B-galactoside bonding protei...
the widespread use of sulfur mustard (sm) as a chemical warfare agent in the past century has proved its long-lasting toxic effects. despite a lot of research over the past decades on iranian veterans, there are still major gaps in the sm literature. transforming growth factor (tgf-β), a cytokine that affects many different cell processes, has an important role in the lungs of pati...
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...
objective: in necrotic immature teeth, intra canal medicaments such as triple antibiotic paste (tap) and calcium hydroxide (ch) are used for root canal disinfection and regeneration treatment. however, the effect of these medicaments on dental pulp fibroblasts has yet to be known. this study aimed to assess the cytotoxicity of ch and tap against cultured human dental pulp fibroblasts (hdpfs) ob...
Objective: In necrotic immature teeth, intra canal medicaments such as triple antibiotic paste (TAP) and calcium hydroxide (CH) are used for root canal disinfection and regeneration treatment. However, the effect of these medicaments on dental pulp fibroblasts has yet to be known. This study aimed to assess the cytotoxicity of CH and TAP against cultured human dental pulp fibroblasts (HDPFs) ...
Abstract Background: Considering the ineffective conventional therapeutic methods for treating different types of wounds, and because of reports of successful use of skin substitutes prepared from co-cultured keratinocytes and fibroblasts on the scaffold of collagen, this study was performed to evaluate the skin substitute on experimentally induced wounds in rats. Materials and methods: Thi...
abstract: background and aim: resin cements are used widely in restorative dentistry regardless of their biocompatibility. the aim of this study was to compare the cytotoxicity of two categories of dental cements consisting of three chemically set cements (fuji i, fuji plus and harvard) and two dual curing cements (biscem and duo-link) by use of mtt assay. materials and methods: in this experim...
Previous studies indicate that organ fibroblasts play an important role in wound healing, collagen production, remodeling processes and pathogenesis of progressive heart, lung, renal and hepatic fibrotic diseases. Several studies suggest a possible inhibitory role for adenosine in the regulation of fibroblast proliferation. The effect of adenosine A2 agonists on proliferation and differentiatio...
