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: 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 ...
introduction: in this study, the effect of para-nonylphenol as an environmental pollutant on viability, morphology and proliferation of bone marrow mesenchymal stem cells was investigated. methods: bone marrow mesenchymal stem cells of rat were treated with the 0.5, 1, 2.5, 3.5 and 5 μm of paranonylphenol for a period of 21 days, then the viability of the cells were estimated using trypan blue ...
the identification of multipotential mesenchymal stem cells (mscs) derived from adult human tissues such as bone marrow and connective tissues has provided exciting prospects for cell-based tissue engineering and regeneration. this review article focuses on the biology of mscs, their differentiation potentials in vitro and in vivo, and their application in tissue engineering. our current unders...
background: recent publications about differentiation of stem cells to germ cells have motivated researchers to make new approaches to infertility. in vitro production of germ cells improves understanding differentiation process of male and female germ cells. due to the problem of using embryonic stem cells (esc), it’s necessary the mentioned cells be replaced with some adult multi-potent stem ...
conclusions our findings showed that the treatment of flaps with bm-msc and aam transplantations significantly promoted flap survival compared to a control group. the viability of the flap was improved by combining bm-mscs with aam matrix scaffolds. materials and methods bm-mscs and aams were transplanted into subcutaneous tissue in the flap area. on the 7th postoperative day, the surviving fla...
human umbilical cord matrix (hucm) is considered as a promising source of mesenchymal stem cells (mscs) due to several advantages over other tissues. the potential of neural differentiation of hucm-mscs is of great interest in the context of treating neurodegenerative diseases. in recent years, considerable efforts have been made to establish in vitro conditions for improving the differentiatio...
objective:more similarity to in vivo medium may help to increase the proliferation and differentiation of cells at in vitro condition. the present study has investigated the effect of a dynamic mediumand nano hydroxyapatite (nha) presence on proliferation and differentiation of mesenchymal stem cells (mscs) to bone cells using electrospun polycaprolactone (pcl) scaffolds. methods: we prepared p...
Pulmonary hypertension is a devastating and refractory disease and there is no cure for this disease. Recently, microRNAs and mesenchymal stem cells emerged as novel methods to treat pulmonary hypertension. More than 20 kinds of microRNAs may participate in the process of pulmonary hypertension. It seems microRNAs or mesenchymal stem cells can ameliorate some symptoms of pulmonary hypertension ...
During epithelial tumor progression, the loss of E-cadherin expression and inappropriate expression of mesenchymal cadherins coincide with increased invasiveness. Reexpression experiments have established E-cadherin as an invasion suppressor. However, the mechanism by which E-cadherin suppresses invasiveness and the role of mesenchymal cadherins are poorly understood. We show that both p120 cat...
