Neural Stem Cells


Neural stem cells (NSCs) may teach us about how cell fate choices are made and which genes regulate these choices. In addition, NSCs might be a source of tissue for cell therapy. Studies focusing on the mechanisms of NSC growth and differentiation suggest they may be more plastic than had been anticipated.

Keywords: stem cell; progenitor cell; embryonic stem cell; transplantation; ex vivo gene therapy

Gene profiling of neural stem cells (NSCs). By taking (a) primary tissue, (b) neurospheres or (c) differentiated neurospheres, (d) it is possible to perform gene‐comparison analysis using differential display or microarray chip analysis to ask questions about genes involved in neural development. The advantage of this method is that the time of differentiation can be used to select for fewer or more gene differences. After cloning of individual genes, they can be reintroduced into the stem cell pool in order to assess their effects on differentiation. cer: cerebellum; ctx: cortex; D: dorsal; EGF: epidermal growth factor; FGF‐2: fibroblast growth factor‐2; Mes: mesencephalon; Thal: thalamus; Oligo: oligodendrocytes; V: ventral.
