multipotent mesenchymal stem cells (mscs) are recently found to alter the tumor condition. however their exact role in tumor development is not yet fully unraveled. mscs were established to perform many of their actions through paracrine effect. thus investigation of msc secretome interaction with tumor cells may provide important information for scientists who are attempting to apply stem cell...

Purpose: The aim is to downregulate the expression level of NS as an important factor in sustaining stem cells and certain types of cancer cells self-renewal ability in bone marrow derived mesenchymal stem cells by RNAi strategy and investigate the effects of absence of NS in these cells. Materials and Methods: Double strand NS-specific and control siRNA oligos were designed and transfected in...

background: several studies have demonstrated the immunosuppresive effects of mes-enchymal stem cells (mscs) in allogeneic or mitogenic interactions. cell-cell contact inhibition and secretion of suppressive soluble factors have been suggested in this re-gard. objective: to investigate if adipose derived mscs could inhibit jurkat lym-phoblastic leukemia t cell proliferation during coculture. me...

Objective(s): In this paper, we discussed natural agents with protective effects against stem cell senescence. Different complications have been observed due to stem cell senescence and the most important of them is “Aging”. Senescent cells have not normal function and their secretary inflammatory factors induce chronic inflammation in body which causes different patho...

Background and Objective: It has recently been shown that the application of amniotic membrane conditioned medium is effective in cancer treatment. In this study, the effect of amniotic stem cells conditioned medium on the activity of Hsp90 and Cdk4 expression, were investigated in cancer cells. Materials and Methods: Two cancer cell lines HeLa and MDA-MB-231 were treated with the supernatan...

differentiation is an epigenetic process which is installed by changes of transcriptional programs over successive cellular divisions. a number of studies have reported the effects of biochemical modifications of chromatin (dna and chromatin proteins) on the regulation of transcription. although, these studies are able to explain how transcription of a given gene is regulated (toward activation...

Introduction: Doxorubicin is frequently used for treatment of several types of cancer. Doxorubicin cardiac toxicity has limited the use of this drug. Corticosteroids may prevent doxorubicin induced cardiotoxicity. Therefore the aim of this study was to evaluate mouse embryonic stem cells derived cardiomyocytes as a model to evaluate the effect of Doxorubicin and dexamethasone. Methods: Mouse ...

Introduction: Amniotic membrane, the innermost layer of extra-embryonic tissue, contains mesenchymal and epithelial stem cells. The amniotic mesenchymal cells have the capability of inhibition of growth of cancer cells. In this research, the effects of amniotic epithelial cells on the viability of cancer cells and the role of apoptosis in this procedure were evaluated. Methods: Amniotic mem...
