Background: Recent publications regarding the differentiation of stem cells to germ cells have motivated researchers to make new approaches in infertility. In vitro production of germ cells improves the understanding of differentiation process of male and female germ cells. Since using embryonic stem cells for this purpose has been associated with tumorogenesis and ethical criticisms, the men...
Stem cells are a good alternative for regenerative medicine because of their characteristics such as self-renewal and differentiation potential. They are classified into different types of stem cells including embryonic stem cells, induced pluripotent stem cells, multipotent stem cells, and ultimately uni-potent stem cells. Mesenchymal stem cells extracted from adult tissues. Due to the lack of...
Isolation, Characterization and Differentiation of Rat Adipose Tissue Derived Mesenchymal Stem Cells
Introduction: Mesenchymal stem cells have the potential of self-renewal and differentiation into different cell types, including blood cells, heart, nerves and cartilage, and have unlimited power for division. These cells can be obtained from cord, before implantation from fertilized cells and also from various tissues of adults although the differentiation power and the ability to reproduce ...
Background: Small molecule Purmorphamin (PMA) is the agonist of smoothened protein in Sonic hedgehog (Shh) signaling pathway. Effect of purmorphamin small molecule on differentiation of mesenchymal cells into bone tissue has been studied previously. Use of Shh causes progression of neural differentiation, and the differentiated cells express specific neural markers. Neurofilament (NF) and acety...
background: mesenchymal stem cells (mscs) are multipotent cells, capable of differentiating into different cell lines.they can sense their surrounding biochemical and biophysical factors, which play major roles in their differentiation toward different phenotypes. therefore, the exposure of these cells to endothelial growth factor (vegf) as well as hemodynamic biomechanical forces, which act on...
BACKGROUND AND OBJECTIVE Molecular gene markers, which can distinguish human bone marrow mesenchymal stem cells from human fibroblasts, have recently been reported. Messenger RNA levels of tissue factor pathway inhibitor-2, major histocompatibility complex-DR-alpha, major histocompatibility complex-DR-beta, and neuroserpin are higher in human bone marrow mesenchymal stem cells than in human fib...
introduction: the field of stem cell biology and regenerative medicine is rapidly moving toward translation to clinical practice. stem cell therapy seems to be a new treatment option for some diseases. so, tracking the distribution of stem cells is crucial to their therapeutic use. based on this fact we labeled human mesenchymal stem cells (mscs) with 111in- oxine for the first time in our coun...
objective(s): studies have confirmed that microgravity, as a mechanical factor, influences both differentiation and function of mesenchymal stem cells. here we investigated the effects of simulated microgravity on neural differentiation of human adipose-derived stem cells (adscs). materials and methods:we have used a fast rotating clinostat (clinorotation) to simulate microgravity condition. re...
Background : Genetic manipulation is an effective strategy to protect cells against environmental damages and enhance their capabilities for therapeutic usage. In order to avoid unwanted side effects, such as cancers, the expression of genes should be temporary increased. The aim of this study was to clone and temporary increased expression of a cell protective gene, Metallothionein 1 (MT1) in ...
