in recent years transdifferentiation technology has enabled direct conversion of human fibroblasts to become a valuable, abundant and accessible cell source for patient-specific induced cell generation in biomedical research. the majority of transdifferentiation approaches rely upon viral gene delivery which due to random integration with the host genome can cause genome instability and tumorig...
Reconstruction of large oral mucosa defects is often challenging, since the shortage of healthy oral mucosa to replace the excised tissues is very common. In this context, tissue engineering techniques may provide a source of autologous tissues available for transplant in these patients. In this work, we developed a new model of artificial oral mucosa generated by tissue engineering using a fib...
BACKGROUND Myofibroblasts play an important role in the development of oral submucous fibrosis (OSF). In the current study, we investigate the effect of curcumin on growth and apoptosis of myofibroblasts derived from human oral mucosa. METHODS Myofibroblasts were generated by incubating fibroblasts, obtained from human oral mucosa, with transforming growth factor-β 1 (TGF-β 1). MTT, PI staini...
We aimed to evaluate the effects of ionizing radiation on the proliferation of gingival fibroblasts and the expressions of proinflammatory cytokines and matrix metalloproteinase-1 (MMP-1), tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) and type I collagen (type I Col) mRNA transcripts. Gingival fibroblasts were treated with radiation doses as follows; 0.5 Gy, 1 Gy, 2 Gy, 4 Gy, 6 Gy, an...
statement of the problem: soft tissue reactive lesions are the most common lesions of the oral cavity. although many studies have shown the interaction of mast cells with fibroblasts and their participation in fibrosis, the role of mast cells in these lesions is not well understood. purpose: the aim of this study was to evaluate the mast cells (mcs) count in oral soft-tissue reactive lesions in...
Wounds of the oral mucosa show faster closure with less scar formation than skin wounds in other areas. A differentially expressed cDNA, wound-inducible transcript 3.0 (wit3.0), was isolated from oral mucosal wound in rats (Sukotjo, C., Abanmy, A. A., Ogawa, T., and Nishimura, I. (2002) J. Dent. Res. 81, 229-235). The purpose of this study was to characterize the wit3.0 gene structure and the f...
Background and Aim: Conventional cancer treatments usually have complex complications. Also, the resistance of cancer cells to treatments is a special point that indicates the need for alternative therapies such as the use of herbal compounds. The aim of this study was to evaluate the anticancer effect of aqueous extract of Persia rose on oral cancer cell line. Material and Methods: In this exp...
Bacteroides forsythus is a gram-negative, anaerobic, fusiform bacterium and is considered to be an etiological agent in periodontal disease. A lipoprotein fraction prepared from B. forsythus cells by Triton X-114 phase separation (BfLP) activated human gingival fibroblasts and a human monocytic cell line, THP-1, to induce interleukin-6 production and tumor necrosis factor alpha production. BfLP...
