spinal cord injury (sci) is a destructive event that often lead to permanent neurologic deficit. current clinical treatments are aimed at preventing secondary damage, promoting regeneration, and replacing destroyed spinal cord tissue, although effective treatments for sci remain limited. cell therapies for treating sci are promising therapy for replacing dead cells, neuroprotection and axon reg...

Basic fibroblast growth factor (FGF2)-responsive definitive neural stem cells first appear in embryonic day 8.5 (E8.5) mouse embryos, but not in earlier embryos, although neural tissue exists at E7.5. Here, we demonstrate that leukemia inhibitory factor-dependent (but not FGF2-dependent) sphere-forming cells are present in the earlier (E5.5-E7.5) mouse embryo. The resultant clonal sphere cells ...

Neural stem cells self-renew and give rise to neurons, astrocytes and oligodendrocytes. These cells hold great promise for neural repair after injury or disease. However, a great deal of information needs to be gathered before optimally using neural stem cells for neural repair. This brief review provides an introduction to neural stem cells and briefly describes some advances in neural stem-ce...

Background: As condition and component of culture determine fate map of spermatogonial stem cells (SSCs), the aim of this study was to evaluate of growth factors GDNF, LIF and RA on proliferation and differentiation of SSC. Materials and Methods: SSCs were cultured in two groups: The first group GDNF and LIF and the second group RA. The number of clumps and colony formation was monitored dur...

Neural stem cells (NSCs) as a heterogeneous multipotent and self- renewal population are found in different areas in the developing mammalian nervous system, as well as the sub-ventricular zone (SVZ) and the hippocampus of the adult brain. NSCs can give rise to neurons, astrocytes and oligodendrocytes. The aim of this study was to differentiate neural stem cells into noradrenergic–like cells in...

The protective effects of erythropoietin on spinal cord injury have not been well described. Here, the eukaryotic expression plasmid pcDNA3.1 human erythropoietin was transfected into rat neural stem cells cultured in vitro. A rat model of spinal cord injury was established using a free falling object. In the human erythropoietin-neural stem cells group, transfected neural stem cells were injec...

Neural stem/progenitor cells capable of differentiating into the neurons and glial cells that populate the mammalian central nervous system (CNS) persist in specific neural stem cell niches that regulate stem cell proliferation, survival and differentiation. There is growing evidence that the extracellular matrix within neural stem cell niches is required for neural stem cell maintenance. Here,...

Strategies of Schwann cell (SC) transplantation to regenerate the peripheral nerve injury involves many limitations. Stem cells can be used as alternative cell sources for differentiation into SCs. Given the high potential of neural crest-derived stem cells for the generation of multiple cell lineages, in this research, we considered whether olfactory ecto-mesenchymal stem cells (OE-MSCs) derive...
