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...

objective(s): umbilical cord blood is a good source of the mesenchymal stem cells that can be banked, expanded and used in regenerative medicine.  the objective of this study was to test whether amniotic membrane extract, as a rich source of growth factors such as basic-fibroblast growth factor, can promote the proliferation potential of the umbilical cord mesenchymal stem cells. materials and ...

By Using the modeling of the mesenchymal (bone marrow) stem cell nanoparticles, the reinstatement of the immune system leads to the treatment of MS, result in the formation of a new immune system for the body by stem cell. The presence of stem cells promotes and strengthens myelination, and that, using simulation and 3D modeling, stem cells can be transmitted correctly to the target and place o...

the complexity of multiple sclerosis (ms) and the incompetence of a large number of promise treatments in ms urge us to plan new and more effective therapeutic approaches that aim to suppress ongoing autoimmune responses and induction of local endogenous regeneration. emerging data propose that hematopoietic, mesenchymal and neural stem cells have the potential to restore self-tolerance, to pro...

objective(s):the mesenchymal stem cells (mscs) have been introduced as appropriate cells for tissue engineering and medical applications. some studies have shown that topography of materials especially physical surface characteristics and particles size could enhance adhesion and proliferation of osteoblasts. in the present research, we studied the distinction effect of 30 and 60 μg/ml of zinc ...

Neurodegenerative diseases are the hereditary and sporadic diseases which are characterized by progressive neuronal loss of the nervous system and are emerging as the leading cause of death, disabilities, and a socioeconomic burden due to an increase in life expectancy. There are many neurodegenerative diseases including Alzheimer’s disease, Parkinson’s, disease, amyotrophic lateral...

objective: the exfoliated human deciduous tooth (shed) contain multipotent stem cells that identified to be a population of highly proliferative and clonogenic .these cells are capable of differentiating into a variety of cell types including neural cells, adipocytes, and odontoblasts. material and methods: normal exfoliated human deciduous incisors collected from six- to nine-years-old childre...

new blood forming vessels are produced by differentiation of mesodermal precursor cells to angioblasts that become endothelial cells (ecs) which in turn give rise to primitive capillary network. human cord blood (hcb) contains large subsets of mononuclear cells (mncs) that can be differentiated into endothelial-like cells in vitro. human mononuclear progenitor cells were purified from fresh umb...
