Introduction: Adult stem cells are the group of cells which conserve their nature in tissues and organs among other cells. In recent years, the researchers reported the existence of stem cells on the Bulge of hair follicles near to the smooth muscle. It is possible to differentiate these stem cells to neural cells by induction of Shh, FGF, and RA factors. Because of existence of these factors ...

Objective: Arsenic, an environmental pollutant, decreases neuronal migration as well as cellular maturation and inhibits the proliferation of neural progenitor cells. Curcumin has been described as an antioxidant and neuroprotective agent with strong therapeutic potential in some neurological disorders. Human adipose-derived stem cells (hADSCs), a source of multipotent stem cells, can self-rene...

in the bone marrow, there are certain populations of stem cell sources with the capacity to differentiate into several different types of cells. ideally, cell transplants would be readily obtainable, easy to expand and bank, and capable of surviving for sufficient periods of time. bone marrow mesenchymal stem cells (bm-mscs) possess all of these characteristics. one of the most important benefi...

Microglia is considered the only cell population of mesodermal origin, which comprises 10% of the cells in brain parenchyma. Recent neural stem cell (NSC) studies demonstrate that the brain has regenerative potential. NSCs do not give rise to microglial cells, however indicating that NSCs alone cannot complete the regenetion of the brain. Although the role of microglia is not fully understood, ...

multiple sclerosis (ms) and its animal model, experimental autoimmune encephalomyelitis (eae), are chronic inflammatory demyelinating disorders of central nervous system (cns). while the cause is unclear, the fundamental mechanism is thought to be destruction of myelin sheaths of neurons through immune system. one of the approaches being proposed in eae therapy is neural stem cells (nscs) trans...

spinal cord injury (sci) is one of the devastating conditions leading to functional and neurological deficits following road traffic accidents. to date, there is no definite treatment for repairing damaged spinal cord tissue. in this regard, cell therapy opens a new window in front of scientists by using different cells such as mesenchymal stem cells, olfactory ensheathing cells, schwann cells,...

enamel matrix derivative emdogain (emd) is widely used in periodontal treatment in spite of the fact that its effect on the developing embryo has not been elucidated. the aim of this study was to investigate the teratogenic effect of emd on the rat embryo neural crest cells. the neural crest is a unique population of cells that migrates from the dorsal neural tube along defined pathways and pro...

neurotrauma is one of the main medical problems that affect considerable number of population especially young persons in all countries. neurotrauma not only is a serious threat for life but also creates various disabilities and consequently imposes large costs to society. following central nervous system (cns) injury, tissue damage occurs via primary and secondary mechanisms. despite many atte...

conclusions taken together, the combination of chemical and growth factors in the two-step induction protocol may improve the efficiency of msc differentiation into neural progenitor cells, and may be a new method for the easy and fast application of mscs in regenerative medicine in the future. results the results of real-time pcr showed that the expression of the gfap, mbp, and map-2 genes aft...
