BACKGROUND Icariin (ICA), a major ingredient of Epimediumbrevicornum, has various pharmacological activities including central nervous system protective functions such as the improvement of learning and memory function in mice models of Alzheimer's disease. It has been reported that ICA can promote regeneration of peripheral nerve and functional recovery. The purpose of this study was to invest...

Transplanted neural stem/precursor cells possess peculiar therapeutic plasticity and can simultaneously instruct several therapeutic mechanisms in addition to cell replacement. Here, we interrogated the therapeutic plasticity of neural stem/precursor cells after their focal implantation in the severely contused spinal cord. We injected syngeneic neural stem/precursor cells at the proximal and d...

Objective(s):Mesenchymal stem cells (MSC) can be isolated from adult tissues such as adipose tissue and other sources. Among these sources, adipose tissue (because of easy access) and placenta (due to its immunomodulatory properties, in addition to other useful properties), have attracted more attention in terms of research. The isolation and comparison of MSC from these two sources provides a ...

The excessive electrical activity of neurons is reported in many diseases including: Parkinson's disease, Alzheimer's disease, and Epilepsy. Electrical overactivity in hippocampus accelerates the depletion of neural stem cell (NSC) and impairs the neurogenesis in hippocampus. It is believed that neurogenesis in hippocampus improves the cognitive functions. In this experiment, we use kindled mod...

Stroke is one of the leading causes of morbidity and disability. There is no definite treatment for brain stroke. Stem cell therapy is useful for treating brain stroke. Mesenchymal stem cells and neural stem cells can be used to treat stroke. In this review, we explained the benefits of mesenchymal stem cells and neural stem cells for stem cell therapy and the advantages of combination stem cel...

Brain injuries that caused by strokes (result of intra partum ischemia) are a frequent cause of prenatal mortality and morbidity with limited therapeutic options. Transplanting human mesenchymal stem cells (hmscs) indicates improvement in hypoxic Ischemic brain injury (HIBD) by secretion growth factor stimulating repair processes (Hmscs) known as multi potent cells which isolated from bone marr...

Currently, researchers are using neural stem cell transplantation to promote regeneration after peripheral nerve injury, as neural stem cells play an important role in peripheral nerve injury repair. This article reviews recent research progress of the role of neural stem cells in the repair of peripheral nerve injury. Neural stem cells can not only differentiate into neurons, astrocytes and ol...

PURPOSE To determine the impact of radiation on neural stem cells and examine the feasibility of neural stem cell sparing using volumetric modulated arc therapy (VMAT) for whole brain irradiation. METHODS Murine neural stem cells were harvested from the sub-ventricular zone (SVZ), cultured and assessed for radio-sensitivity and differentiation potential in response to radiation (0-6Gy). Clono...

Human parthenogenetic stem cells are derived from the inner cell mass of blastocysts obtained from unfertilized oocytes that have been stimulated to develop without any participation of male gamete. As parthenogenesis does not involve the destruction of a viable human embryo, the derivation and use of human parthenogenetic stem cells does not raise the same ethical concerns as conventional embr...
