the effects of mobile phone exposure on humans, due to its potential health hazards, have become the focus of interest since many years ago. the effect of global system for mobile communications (gsm 900 mhz) on growth and proliferation rate of mesenchymal stem cells was assessed at the different distances and intensities of radiation. a subscriber identity module (sim) card was inserted to thi...

cord blood hematopoietic stem cells are widely used as an alternative source for hematopoietic stem cells transplant. increasing rate of patients who need hematopoietic stem cells transplant and many advantages of cord blood in comparison to bone marrow hematopoietic stem cells, have promoted banking of cord blood units. cord blood banking requires accurate steps in donor selection, cord blood ...

objective(s) arsenic compounds are potent human carcinogen and produce a variety of stress responses in mammalian cells. recently sodium arsenite has been recommended to be used as anti malignancy drug by american food and drug administration (fda). in this study, we aimed to determine the apoptosis inducing effect of sodium arsenite on rat bone marrow mesenchymal stem cells exposed in vitro. m...

background: unrestricted somatic stem cells (ussc) are cord blood stem cells that have been considered as candidates for the regulation of immune responses. therefore, potential exists for their use in the suppression of immune response after transplantation surgery. objective: the aim of this study was evaluation of the effect of ussc on mixed lymphocyte reaction (mlr) as a model for graft rej...

background: recently, embryonic stem (es) cells have become very important resources in basic medical researches. these cells can differetiate into derivatives of all primary germ layers. objectives: in order to isolate embryonic stem cells in vitro, the blastocyst were cultured and the morphological aspects, population doubling time, alkalin phosphatse and differentiation properties of the cel...

background: metastasis and recurrence of colorectal cancer after treatment is attributed to stem cells. the aim of this study was to determine the relationship between the expression of stem cell marker cd166 in colorectal cancer by immunohistochemistry and clinicopathologic parameters.methods: from 2006 to 2012, 121 colectomy specimens of patients with colon cancer that were operated in babol ...

background: the uterus is a dynamic tissue responding to hormonal changes during reproductive cycles. as such, uterine stem cells have been studied in recent years. transcription factors oct4 and sox2 are critical for effective maintenance of pluripotent cell identity. objective: the present research evaluated the mrna expression of oct4 and sox2 in the uterine tissues of ovariectomized mice tr...

Introduction: Mesenchymal stem cells can be isolated from adult tissues, such as the adipose tissue, or other sources. Among all these sources, adipose tissue because of easy access, and placenta due to its immunomodulatory properties, in addition to another useful properties, were attracted more attention to themselves. Isolation and comparing these two different sources can help us for acces...
