Background: Heart failure is one of the most common cardiovascular disorders and is considered a chronic, progressive and debilitating disorder. The medical treatment of this disease is accompanied by many problems. Today, stem cells are being used increasingly to reduce the problems of heart failure treatments. Since pro-inflammatory cytokines play an important role in the prognosis and progre...

background: the aim of this study was to investigate the percentage of the stem cells population in human endometrial tissue sections and cultured cells at fourth passage. methods: human endometrial specimens were divided into two parts, one part for morphological studies and the other part for in vitro culture. full thickness of human normal endometrial sections and cultured endometrial cells ...

Introduction: Stroke is the third important reason of death in adults and an important cause of adult disability. Previous studies suggest that TGF-alpha can induce neurogenesis after stroke. Here in, we studied neurogenesis effects of the TGF-alpha on subventricular zone following ischemia-reperfusion. Male wistar rats (250-300 g) were divided into ischemia and treatment groups. After inductio...

renal ischemia-reperfusion (ir) contributes to the development of acute renal failure (arf). oxygen free radicals are considered to be principal components involved in the pathophysiological tissue alterations observed during renal ir. the purpose of this study was to investigate the combination effect of melatonin (mel) and erythropoietin (epo), which are a potent antioxidant and anti-apoptoti...

background: transplantation approaches are interventions currently available to apply to the devastating problem of spinal cord injury (sci). olfactory ensheathing cell (oec) and embryonic stem cell (esc) are considered to be promising therapeutic strategies . in this study, we compared the potential use of oecs and neurally pre-differentiated escs in contusion spinal cord. methods: oecs were h...

background: mesenchymal stem cells (mscs) have been recently received increasing attention for cell-based therapy, especially in regenerative medicine. however, the low survival rate of these cells restricts their therapeutic applications. it is hypothesized that autophagy might play an important role in cellular homeostasis and survival. this study aims to investigate the regenerative potentia...

background: wound healing of burned skin remains a major goal in public health. previous reports showed that the bone marrow stem cells were potent in keratinization and vascularization of full thickness skin wounds. methods: in this study, mesenchymal stem cells were derived from rat adipose tissues and characterized by flowcytometry. staining methods were used to evaluate their differentiatio...

human mesenchymal stem cells (hmscs), which also called mesenchymal stromal cells, are multipotent stem cell. human mscs typically are positive for the surface markers cd44, cd73, cd90, cd105, cd106, and also negative for hematopoietic markers cd34 and cd45.these cells can be isolated from postnatal bone marrow, adipose tissue, placenta, and scalp tissue, as well as from various fetal tissues. ...

in this present study, we examined the differentiation potential of human bone marrow derived mesenchymal stem cells (hbmscs) into hepatocytes on a three-dimentional (3d) nanofibrous scaffold formed by poly (ε-caprolactone) (pcl), collagen and polyethersulfone (pes). the nanofiber was prepared by the electrospining technique. hbmscs were isolated using combining gradient density centrifugation ...
