Objective(s): Chronic myelogenous leukemia (CML) is a chronic myeloproliferative disorder characterized by the accumulation of myeloid cells with a chromosomal translocation known as the Philadelphia chromosome. In this study, we investigated the roles of miR-570 in CML development. Materials and Methods: Expression of miR-570 in CML samples and cell lines was determined by qRT-PCR. Glucose upt...

Background: Progesterone is an endogenous immunomodulator that suppresses T cell activation during pregnancy. The stimulation of membrane progesterone receptors (mPRs) would seem to be the cause of rapid non-genomic responses in human peripheral T cells, such as an elevation of intracellular calcium ([Ca2+] i) and decreased intracellular pH (pHi). Mifepristoneimmune cells compared with progeste...

we aimed to develop a cost-effective and robust method to predict drug resistance in individualpatients. representative tissue fragments were obtained from tumors removed from femalepatients, aged 24-74 years old. the tumor tissue was taken by a histopathology’s or a surgeonunder sterile conditions. cells obtained by enzymatic dissociation from tumor after surgery, werecultured as a monolayer f...

objective: osteon has been introduced as a bone substitute material. it is biphasic calcium phosphate (bcp) that use in dentistry. the aim of the present study was to evaluate the effect of osteon on the proliferation, cell viability and differentiation of saos-2 cells in vitro. also it was compared with cerasorb bone graft. materials and methods: two different bone grafts materials, osteon an...

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 ...

In this syudy a continuous bovine kidney cell line derived from a primary bovine kidney cells was established for the first time in Iran. The cells were originating from two-day-old normal male calf of Holstein breed. The cell cultures were continuously passaged following complete proliferation of primary cells. The specific properties or characteristics of the cell were defined using cytogenet...

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(s): the study aimed to investigate the effects of adrenomedullin (adm) and proadrenomedullin n- terminal 20 peptide (pamp) on angiotensin ii (angii)-stimulated proliferation in vascular smooth muscle cells (vsmcs). materials and methods: thoracic aorta was obtained from wistar rats and vsmcs were isolated from aorta tissues and then cultured. in vitro cultured vsmcs were stimulated wi...

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 ...
