The replacement of neural stem cells, either endogenous or stem cell-derived neural stem cells, into impaired brain is usually highly expected as a possible therapeutic mean for neurodegenerative diseases. In this review, clinical features and current routinely treatments of age-related neurodegenerative diseases are documented. Noteworthy, we presented the promising evidence of neural stem cells and their derivatives in curing such diseases, together with the remaining challenges to achieve the best outcome for patients. for years[41]. In order to generating a satisfactory number of neural stem cells, it is assumed that cell proliferation should be prevalent in the early developmental timing, and that more cells differentiate into a specific cell type during the latter phases. This indicates that there is a high possibility for producing two undifferentiated daughter cells at early stages of development (symmetric division), and later cell division prefers the production of differentiated neurons and glial cells (asymmetric division). Neural stem cells residing in the developing neocortex undertake both symmetrical and asymmetrical divisions throughout their life span[42]. Several pathways that interconnect to control cell proliferation have been well documented. Perhaps the best comprehensive studies are those cell signalling pathways that are brought on by growth factors. All types of neural stem cells are generally responsive to multiple family of growth factors; however, the exact set of growth factors should be exclusively required for neural stem cells at specific stages and alpha-Cyperone could distinguish stage-specific neural stem cells. Early neural stem cells entirely respond to fibroblast growth factor2 (FGF2 or bFGF), and the loss of FGF ligands or FGF receptors results in a significant diminution of neural stem cell proliferation[43]. On the other hand, the late emerging neural stem cells demand either FGF2 or alpha-Cyperone epidermal growth factor for their proliferation[44]. It is noted that cell self-renewal is usually tightly connected to this growth factor responsive potential. Self-renewal is considered as a pivotal identity of neural stem cells because it is usually indispensable for the cells to preserve themselves, therefore at least one of the progeny retains comparable molecular characteristics to the mother stem cells. It is important to note that while a process of self-renewal occurs, neural stem cells may undergo changes in their abilities to produce different progeny during development[45]. Multipotency To be characterised as a neural stem cell in the CNS, a cell must contain a differentiation potential to give rise to neurons, astrocytes and oligodendrocytes[41,46]. It is noted that neural stem cell plasticity is usually progressively restricted as development advances, for example early neural stem cells appear to be specified a wide range of phenotypes, from anterior to posterior parts of the brain, while late neural stem cells is only restricted to its origin[47]. It was presented that adult neural stem cells exist mainly in two areas of the brain, subventricular zone (SVZ) and sub granular zone (SGZ), can be propagated alpha-Cyperone for years[41]. Neural stem cells in the SVZ can differentiate into olfactory neurons, while neural stem cells of SGZ differentiate into granular neurons of the dentate gyrus. However, when transplanting SVZ neural stem cells into dentate gyrus, they differentiate into calbindin-positive granular cells, while transplanting SGZ neural stem cells into the olfactory bulb, tyrosine- and calretinin hydroxylase-positive cells were observed. Furthermore, when transplanted into the developing eyes, hippocampal neural stem cells exhibited several morphological and immunological properties of retinal cells, including photoreceptors[48]. This implies that the.
