background: mesenchymal stem cells (msc) have ability to regulate immune response via proinflamatory cytokines. in this study we aimed to investigate the effect of different mechanism for t cell activation and adjacency on immunoregulatory properties of msc. methods: bone marrow mscs were purchased and t cells were obtained from whole blood sample. t cells were activated by two different mechan...

abstract background: sodium arsenite (sa) recently has been recommended to be used in malignancy therapy. our studies showed, sa in short and long period of treatment caused reduction of rats bone marrow mesenchymal stem cells (mscs) viability and induced caspase dependent apoptosis. the aim of this study was to investigate the effect of sa on osteogenic differentiation of mscs. methods: mscs w...

background chronic allograft nephropathy(can)  is one of the most common causes of chronic and end stage renal disease. it  is defined with mainly tubular atrophy and  interstitial fibrosis and no evidence of any other etiology, or functional disorder that caused at least three months after transplantation . control of risk factors (htn,dm,hlp, …) and limiting  usage of calcineurin inhibitors o...

Discovering a cell type with the highest efficiency and the least side-effects is one of the priorities of scientists active in this field. Of all the cells, mesenchymal stem cells have been and still are of interest to the researchers for use in pre-clinical and clinical studies due to being easily accessible, pluripotency, secretion of numerous growth factors, low risk of immunological reject...

Introduction: Chemokine receptors are found on the surface of stem cells. There have been 19 distinct chemokine receptors described in mammals. Chemokines are major players in migration and homing. Therefore, changes in their levels or function can help us to increase the migratory potential of these cells. Valproic acid differs in structure from other drugs in common use. The way in which Va...

mesenchymal stem cells (mscs),as the major stem cells for cell therapy, have been studied from different aspects in pre-clinical and clinical settings for more than a decade. these cells modulate the immune system (humoral and cellular immune responses) in vitro by producing soluble factors (anti-inflammatory molecules) and/or making cell-cell contacts. hence they could be used in regenerative ...

Background and Aims: Mesenchymal stem cells (MSCs) are a preferred cell source for the generation of hepatocyte-like cells in regenerative medicine. They can be isolated from different sources, including adipose tissues. The Raman spectroscopy approach was evaluated for quick and efficient identification of MSCs differentiation status and a broader perspective on cell differentiation. Material...

Background and Objective: Mesenchymal stem cells (MSCs) promote metastasis in colorectal cancer; however, the mechanism underlying this process is not fully understood. Epithelial to mesenchymal transition (EMT) is a key step in tumor acquisition of metastatic phenotype. We aimed to investigate the effect of MSCs on the expression of EMT markers, as well as cancer stem cell markers in HT-29 col...
