the proliferation of hepatocellular carcinoma (hcc) cells is one of the leading causes of liver cancer mortality in humans. the inhibiting effects of matrine on hcc cell proliferation have been studied, but the mechanism of that inhibition has not been fully elucidated. since, apoptosis plays an important role in hcc cell proliferation. we examined the apoptosis-inducing effect of matrine on tu...

background: despite the extensive information available in the literature, cell surface marker signature of human amniotic epithelial cells (haecs) remains controversial. the aim of the present study was to characterize immuno-phenotypic features, proliferative capacity and immunogenicity of haecs. we also tested whether expression of some cell surface markers is influenced by the type of tryps...

The cytotoxic activity of ethanolic extracts of Thymus vulgaris, Thuja orientalis and Achillea millefolium was investigated on various growing tumor cell lines. MTT colorimetric assay was used for measuring the inhibition of cell proliferation. All of the three extracts showed a relatively dose-dependent inhibition of proliferation of human breast cancer (SK-Br-3, MDA-MB-435) and leukemia ...

cancer cell-stromal cell interaction plays a crucial role in the growth and invasion of tumor cells of various organs. it has been recently suggested that adipocytes and preadipocytes, two specific types of stromal cells, affect the biological behavior of variety of breast cancer cell lines. in spite of few investigations, there is a controversy in the literatures about the effects of adipocyte...

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...

conclusions according to our results, silymarin injection caused significant differentiation of mscs to neurons and neuroglia that could be a promising approach for treating a variety of brain injuries. results expression of cd29 and cd90 markers that are characteristic of bmmscs were confirmed by flow cytometry experiments. the data demonstrated that proliferation and number of progenitor cell...

results there was a significant difference in prevalence of ebv presence between patients and controls. the ebv was found by rt-pcr in 19 (63.33%) out of 30 patients and only in eight (26.7%) of 30 control samples. the p = 0.004, was calculated using chi-square test (or: 4.75; 95% ci: 1.58 ‒ 14.25). conclusions our study is the first investigation performed on patients with lch and its possible...

introduction : deproteinized bovine bone mineral (bio-oss) is a xenogenic bone substitute, widely used in maxillofacial bone regeneration. the aim of this in vitro study was to investigate its influence on the growth behavior of human osteosarcoma cell line, saos-2 culture, and compare it with the physiologic dose of dexamethasone, an inductive factor for osteoblasts. materials and methods: hum...

background the mutations of lhbs in pre-s, especially in pre-s2, are definitive in hepatocellular carcinoma (hcc) associated with hbv. however, the mechanisms of the n-glycosylation modification in lhbs are unclear. the n-glycosylation modification of lhbs affects endoplasmic reticulum stress, cell proliferation and its secretion which was further studied. objectives the objectives of our studi...
