background: bone marrow-derived mesenchymal stem cells (bmmscs) transplantation has been considered as a promising milestone in liver fibrosis treatment. however, low amounts of homing are a major obstacle. we aimed to investigate the role of melatonin pretreatment in bmmsc homing into experimental liver fibrosis. methods: bmmscs were obtained, grown, propagated and preconditioned with 5 µm mel...

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...

abstractbackground: fetal bovine serum (fbs) is widely used in cell culture laboratories,risk of zoonotic infections and allergic side effects create obstacles for its use inclinical trials. therefore, an alternative supplement with proper inherent growthpromotingactivities is demanded.objective: to find fbs substitute, we tested human umbilical cord blood serum(hucs) for proliferation of human...

Objective(s):Bone marrow-derived mesenchymal stem cells (BMSCs) have attracted significant interest to treat asthma and its complication. In this study, the effects of BMSCs on lung pathology and inflammation in an ovalbumin-induced asthma model in mouse were examined. Materials and Methods:BALB/c mice were divided into three groups: control group (animals were not sensitized), asthma group (an...

background: embryonic stem cells (esc) are pluripotent cells which have been used as a model to study the mechanism that control the embryogenesis and early mammalian development in vitro. the aim of this study was to isolate and produce embryonic stem cells from late blastocyst stage embryos in mice. materials and methods: blastocyst stage embryos from pregnant nmri mice were obtained and cult...

Mesenchymal stem cells (MSCs) show high expression of PD-L1. Exosomes can transmit signals between tumor and stromal cells; however, the effect tumor-derived exosomes on cell signaling pathways is unclear. The PD-L1 in bone marrow mesenchymal (BMMSCs) was detected by western blot RT-PCR. effects gastric cancer line-derived BMMSC migration conditioned medium from educated BMMSCs were analyzed. O...

introduction:   mesenchymal stem cells have the potential of self-renewal and differentiation into different cell types, including blood cells, heart, nerves and cartilage, and have unlimited power for division. these cells can be obtained from cord, before implantation from fertilized cells and also from various tissues of adults although the differentiation power and the ability to reproduce ...

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...
