This study investigated the feasibility of replacing urinary epithelial cells with oral keratinocytes and transforming growth factor-β1 (TGF-β1) small interfering RNA (siRNA)-transfected fibroblasts seeded on bladder acellular matrix graft (BAMG) in order to reconstruct tissue-engineered urethra. Constructed siRNAs, which expressed plasmids targeting TGF-β1, were transfected into rabbit fibrobl...

Aim Our aim was to evaluate gene expression profiling of fibroblasts from human alveolar mucosa (M), buccal attached gingiva (G) and palatal (P) tissues during early wound healing, correlating it with clinical response. Materials Methods M, G P biopsies were harvested six patients at baseline 24 hr after surgery. Clinical response evaluated through Early Healing Score (EHS). Fibrotic markers au...

The predisposition of cigarette smokers for development of respiratory and oral bacterial infections is well documented. Cigarette smoke can also contribute to yeast infection. The aim of this study was to investigate the effect of cigarette smoke condensate (CSC) on C. albicans transition, chitin content, and response to environmental stress and to examine the interaction between CSC-pretreate...

Molecular crosstalk between cancer cells and fibroblasts has been an emerging hot issue in understanding carcinogenesis. As oral submucous fibrosis (OSF) is an inflammatory fibrotic disease that can potentially transform into squamous cell carcinoma, OSF has been considered to be an appropriate model for studying the role of fibroblasts during early stage carcinogenesis. In this sense, this stu...

in this study, we have investigated the proliferative response of human dermal fibroblasts isolated from normal and psoriatic individuals to different cytokines. we found that il-1, tnf (α) and egf are stimulatory whereas ifn « and 1 both showed inhibitory activity on fibroblast proliferation. il-6 a more recently described cytokine, showed no detectable effects on cell proliferation. investiga...

Oral mucosa heals faster with less scar formation than skin and a hypertrophic scar is very rare in the oral cavity, but its mechanism has not been elucidated enough. To elucidate whether or not there are differences in growth factor expression between fibroblasts derived from buccal mucosal and normal skin, we investigated the expression of hepatocyte growth factor (HGF), keratinocyte growth f...
