Objective(s): The present study was aimed to evaluate the time-mannered and dose-dependent effects of 5α-dihydrotestosterone (5α-DHT) on the proliferation and differentiation of bone forming cells using MC3T3-E1 cells. Materials and Methods: Cell proliferation was analyzed using MTS and phase contrast microscopic assays. Osteogenic differentiation was assessed through a series of in vitro exper...

In vitro propagation of rose has played a very important role in rapid multiplication of species with desirable traits and production of healthy and disease-free plants. Micropropagation using nodal segments of Rosa canina under different combinations of BAP, GA3 and NAA on MS and VS, medium was investigated. The results showed that the highest shoot proliferation was obtained on VS medium cont...

objective: cell vital function has correlation with mechanical loadings that cell experiences. here, effects of in-vitro combined cyclic-static stretch on proliferation of human mesenchymal stem cell (hmsc) were evaluated. materials and methods: hmscs were cultured on gelatin coated elastic membranes, and exposed to stretch loading. four different regimes of cyclic, static, combined cyclic-sta...

background: numerous molecules in papaveraceae family display interesting cytotoxic activities against tumor cell lines in vitro and hints of anticancer activities in vivo have been reported in a few cases. objective: numerous molecules in this family display interesting cytotoxic activities against tumor cell lines in vitro and hints of anticancer activities in vivo have been reported in a few...

  Objective(s): Recent investigations show that both proliferation and secretion of macromolecules by cells can be regulated by low level laser therapy (LLLT). The aim of this study was to determine whether LLLT could induce a bio-stimulatory effects on human gingival fibroblasts (HGF3-PI 53). Therefore, the effect of laser irradiation on human gingival cell proliferation and collage...

background: stem cell factor (scf) is a transcriptional factor which plays crucial roles in normal proliferation, differentiation and survival in a range of stem cells. objective: the aim of the present study was to examine the proliferation effect of different concentrations of scf on expansion of human endometrial cd146+ cells. materials and methods: in this experimental study, total populati...

garlic, an antioxidant plant, can react with amino groups of proteins to form schiff bases. as diabetes leads to glycation of various proteins and this in turn has some effects on the structure of proteins and biochemical activity of them, the inhibition of this process seems very vital. for several years researchers in this field have done their best to recognize the antidiabetic compounds. th...

conclusions these results indicate that a. kellalensis extracts exert potent anti-rotaviral activity only after viral adsorption. the two extracts from a. kellalensis showed a good selectivity index. also these results suggest that extracts prepared from the flowers of a. kellalensis may be potential anti-rotaviral agents in vivo and be useful in veterinary medicine. background achillea kellale...
