background menstrual blood-derived stem cells (menscs) are a novel source of stem cells that can be easily isolated non-invasively from female volunteered donor without ethical consideration. these mesenchymal-like stem cells have high rate of proliferation and possess multi lineage differentiation potency. this study was undertaken to isolate the menscs and assess their potential in differenti...

background: human embryonic stem cells (hesc), which are derived from the inner cell mass of the blastocysts, have been considered to be pluripotent cells. in this study we examine the differentiating potential of hesc into hepatocytes by characterization of the expression of endoderm and liver-specific genes. methods: hesc were cultivated in suspension to form aggregates, the embryoid bodies. ...

objective(s):the application of stem cells holds great promises in cell transplants. considering the lack of optimal in vitro model for hepatogenic differentiation, this study was designed to examine the effects of laminin matrix on the improvement of in vitro differentiation of human bone marrow mesenchymal stem cells (hbm-msc) into the more functional hepatocyte-like cells. materials and meth...

objective(s):in previous investigations, we have shown para-nonylphenol (p-np) caused significant reduction of proliferation and differentiation of rat bone marrow mesenchymal stem cells (mscs) in vitro. in this study, we first treat the rats with p-np, then carried out the biochemical and morphological studies on mscs. materials and methods: proliferation property of cells was evaluated with t...

background: since embryonic stem (es) cells have the dual ability to proliferate indefinitely and differentiate into multiple tissue types, es cells could potentially provide an unlimited cell supply for human transplantation. objective: in order to study the differentiation of mouse embryonic stem (mes) cells, they were cultured in suspension by using es media without leukemia inhibitory facto...

background: stem cell differentiation is a process composed of vast variety of factors which are controlled by a network of certain mechanisms. this study aims to determine the possible role of dna methylation, a potent regulator of vhl, ecad and runx3 genes during erythroid differentiation driven by mir-451. materials and methods: to determine the methylation status of promoters and the expres...

background: mesenchymal stem cells (mscs) are multipotential cells and their therapeutic potency is under intense investigation. studying the effect of different induction factors on mscs could increase our knowledge about the differentiation potency of these cells. one of the most important sources of these factors in mammalian body is platelet. platelet lysate (pl) contains many growth factor...

Background: Hair follicle stem cells (HFSCs) located in the bulge area has shown to be highly proliferative and could differentiate into neurons, glia, smooth muscle cell, and melanocytes in vitro. Simvastatin is an HMG-CoA reductase inhibitor that exerts pleiotropic effects beyond simple low-density lipoprotein lowering and has a similar impact on the differentiation of bone marrow stromal cel...
