Background: Iron is an essential trace element in cell proliferation. Several investigations demonstrate that iron deprivation inhibits cell proliferation. However, the impact of iron on telomerase activity of activated lymphocytes remains unexplained to date. Objective: In this study, the effect of iron on the proliferation and telomerase activity of lymphocytes stimulated by phytohemagglutini...

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: Study in design to incorporate accelerated proliferation correction factors into linearquadratic and multiple-component models. Materials and Methods: Accelerated proliferation rate correction factor has been incorporated into the linearquadratic and the multiple component models by applying accelerated exponential cell growth to explain the tumor cell kinetics and estimates proper ...

background: bone marrow derived mesenchymal stem cells (mscs) are a population of multipotent progenitors which have the capacity of proliferation and differentiation into mesenchymal lineage cells. hypoxia could promote the proliferation of mscs. micro-rnas are endogenous rnas that can play an important role in some processes such as proliferation and differentiation. mir-210 could help for be...

objective(s): lipocalin2 (lcn2) gene is highly expressed in response to various types of cellular stresses. the precise role of lcn2 has not been fully understood yet. however, it plays a key role in controlling vital cellular processes such as proliferation, apoptosis and metabolism. recently it was shown that lcn2 decreases senescence and increases proliferation of mesenchymal stem cells (msc...

Background  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 collagen type I gene ...

Apple is one of the most important temperate-zone fruit trees in the world. Micropropagation of apple scion and rootstocks is an important method of rapid production of healthy and disease-free plants. In this research, in vitro propagation of three apple roottocks including Azayesh-Esfahan, Morabbaee-Mashhad and M9 was investigated. Shoot proliferation carried out in two basal media (MS and WP...

in 6 patients with iron deficiency anemia the proliferation of epi, thelial cells of glomeruli were prominent associated with edema and adherence of bowman's capsule in kidney biopsy, the cause of proliferation is not known.
