In vitro derivation of germ cells from different stem cells sources has been challenging in the treatment of male infertility. MicroRNAs (miRNAs) have an essential role in gene expression at post-transcriptional level. The aim of this research was to find more about miRNA-17 and miRNA-146 expression during differentiation of spermatogonial stem cell like cells (SSC like cells) from mouse bone m...

Spinal cord injury (SCI) is a neurologic disorder that have a significant impact on quality of life, life expectancy, and economic burden. SCI leads to irreversible neuronal loss and ultimately leads to paralysis. Mesenchymal stem cells (MSCs) are a promising source for cellular therapy because they have possessed the capacity of self-renewal and differentiation to several distinct mesenchymal ...

oct4 یکی از ژنهای مهم و کلیدی در سلولهای بنیادی است و کد کننده یک فاکتور رونویسی است که نقش کنترل بیان ژنهای مرتبط با بنیادی بودن (stemness) را به عهده دارد. با فرایند پیرایش افتراقیalternative splicing) ) حداقل سه واریانت مختلف با عملکرد متفاوت از این ژن سنتز میگردد. عمده ترین نقش این ژن کنترل پرتوانی (pluripotency) و خود باز آفرینی (self-renewal) در سلولهای بنیادی است، بطوریکه بیان این ژن نشا...

Objective(s): Cord blood (CB) is known as a valuable source of hematopoietic stem cells (HSC). Identifying strategies that enhance expansion and maintain engraftment and homing capacity of HSCs can improve transplant efficiency. In this study, we examined different culture conditions on ex vivo expansion and homing capacity of CB-HSCs. Materials and Methods: In this study, 4-5 different units o...

objective: menstrual blood stromal stem cells (mbscs) share some phenotypic and functional similarities with mesenchymal stem cells (mscs). mscs are shown to inhibit either the function or generation of different immune cells, including dendritic cells (dcs). however, data regarding mbscs’ potential effects on immune system cells are elusive. here, we examine whether mbscs affect the generation...

human bone marrow derived mesenchymal stem cells (hbmscs) have the potential to differentiate into cells such as adipocyte, osteocyte, hepatocyte and endothelial cells. in this study, the differentiation of hbmscs into endothelial like-cells was induced in presence of vascular endothelial growth factor (vegf) and insulin-like growth factor (igf-1). the differentiated endothelial cells were exam...

Background: Recent clinical studies of treating traumatic brain injury (TBI) with autologous adult stem cells led us to compare effect of intravenous injection of bone marrow mesenchymal stem cells (BMSC) and bone marrow hematopoietic stem cell mobilization, induced by granulocyte colony stimulating factor (G-CSF), in rats with a cortical compact device. Methods: Forty adult male Wistar rats w...
