background: the use of stem cells is considered as an appropriate source in cell therapy and tissue engineering. differentiation of human induced pluripotent stem cells (hipscs) to hepatocyte-like cells (hlcs) on mouse embryonic fibroblasts (mefs) feeders is confronted with several problems that hinder the clinical applications of these differentiated cells for the treatment of liver injuries. ...

the aim of this study was to isolate mouse embryonic stem cells from late blastocyst stage embryos and to use them as a model system for the study of hematopoietic induction outside the embryo by coculturing of embryonic stem cells with bone marrow stromal cells. blastocyst stage embryos from pregnant nmri mice were obtained and cultured for 1-2 days in dmem medium. the inner cell masses formed...

background: the aim of this study was optimization of the polyfect gene delivery method of pcdna3.1 expression vector transfected with the mouse pdx-1 gene in three different kinds of mesenchymal stem cells and hepa cells as well as comparison of transfection efficiency leading to expression of the mentioned gene in the cell types used. materials and methods: rat bone marrow-derived mesenchymal...

background: adipose-derived stem cells (adsc) could be an appealing alternative to bone marrow stem cells (bmsc) for engineering cell-based osteoinductive grafts. meanwhile, prior studies have demonstrated that melatonin can stimulate osteogenic differentiation. therefore, we assayed and compared the melatonin effect on osteogenic differentiation of bmsc with that of adsc. methods: mesenchymal ...

bone marrow mesenchymal stem cells can differentiate into neurons and astrocytes after transplantation in the spinal cord injury of rats. although bone marrow mesenchymal stem cells are known to protect against spinal cord injury through anti-apoptotic effects, but generation of neural stem cells with large number and safety protocols unclear. in the present study, described the differentiation...

low-intensity laser therapy (lilt) is defined to supply direct biostimulative light energy to the cells. while several studies have demonstrated that lilt has stimulating effects on bone cells and can accelerate the repair process of the bone, others reported delayed fracture healing or no effects after lilt. the aim of this article was to review the studies evaluating the biomodulation effects...

helicobacter pylori was the main cause of gastric cancer (gc) in all over the world that results in intestinal- and diffuse-type carcinoma. infection by this bacterium remains chronic for a long time. in vitro studies have highlighted the role of stem cells in gc. h. pylori infection results in tissue injury and the adult/tissue stem cells subsequently start to replace the dead cells. the genet...

this investigation aimed to examine the protective function of vitamin e on rat bone marrow mesenchymal stem cells (mscs) treated with cadmium chloride. rat bone marrow mscs were extracted using flashing-out and cultured in dmem containing 10% fbs and 100 u/ml pen/strep. at the end of the third passage, cells were divided into 4 groups including control, cadmium chloride, cadmium chloride + vit...
