objective(s): umbilical cord blood is a good source of the mesenchymal stem cells that can be banked, expanded and used in regenerative medicine.  the objective of this study was to test whether amniotic membrane extract, as a rich source of growth factors such as basic-fibroblast growth factor, can promote the proliferation potential of the umbilical cord mesenchymal stem cells. materials and ...

conclusions p. gingivalis and p. intermedia could play a role in implant failure by changing the expression profiles of genes related to bone formation and resorption. results viability was reduced to 56.8% (p. gingivalis) and 52.75% (p. intermedia) at 1000 multiplicity. amongst 48 genes examined, expressions of bmper, smad1, il8 and nfrkb were found to be highly upregulated by both bacterial c...

background: keratinocyte growth factor (kgf) is a potent epithelial mitogen that acts by binding the kgf receptors (kgfrs) expressed on epithelial cells and regulates proliferation and differentiation. the objective of this study was to investigate the expression of kgf in the epithelium in oral precancer. materials and methods: archival tissues of oral submucous fibrosis (smf) and leukoplakia ...

introduction: pulsed dye laser (pdl) is an important treatment for superficial infantile hemangioma, but few studies report on its cellular mechanism. the aim of this study was to evaluate alterations of serum vascular endothelial growth factor (vegf) level in infantile hemangioma (ih) patients after laser treatment and effects of pdl irradiation on human umbilical vein endothelial cells (huvec...

  Background and Objective: Vascular endothelial growth factor (VEGF) and its receptors (VEGF-R1 and R2) are major regulators of angiogenesis. This study was designed to assess serum levels of VEGF and VEGF-R1 and their prognostic significance in newly diagnosed childhood acute leukemia. Materials and Methods: For this purpose, VEGF and VEGF-R1 were determined using enzyme linked immuno-sorba...

background: the anticancer agent imatinib (im) is a small molecular analog ofatp that inhibits tyrosine kinase activity of platelet derived growth factors (pdgfs)and stem cell factor (scf) receptor in cancer cells. however these factors have a keyrole in regulating growth and development of normal sertoli, leydig and germcells.objective: the aim of this study was to determine cell viability, pd...

an appropriate differentiation of distinct human cd4+ t cell subset is critical for manipulating these cells for using in immunity related diseases. despite various attempts to clarify the role of different factors involved in th17 differentiation, many crucial contradictions yet remained to be optimized. although it has been shown that the differentiation of in-vitro th17 cells culture conditi...

background: the aim of this study was to evaluate over expression of epidermal growth factor receptor (egfr) gene in localized prostate cancers and determine its relation with clinical and pathological factors affecting the progression of the disease. methods: in the tissue samples of the patients with prostate cancer undergoing radical prostatectomy, egfr expression was evaluated by immunohist...
