Abstract:
:Neural stem cells (NSCs) are self-renewable, multipotential cells capable of differentiating into the three major neural cell types, but the mechanisms which regulate their development are not fully understood. Both basic fibroblast growth factor (bFGF) and epidermal growth factor (EGF) promote the proliferation of NSCs. However, studies on the role of FGFs in the differentiation of EGF-expanded NSCs are still incomplete. We have studied the expression of distinct FGF receptors (FGFRs) in the progeny of EGF-expanded NSCs isolated from E15 rat striatum. In situ hybridization analysis and immunocytochemistry showed a developmentally related expression pattern and a cell lineage-specific distribution of these receptors. FGFR1 and FGFR2 were identified in many early precursors and in the oligodendrocyte lineage. The latter receptor was also present in a subpopulation of astrocytes. FGFR3 was detected in a restricted population of early precursors, in oligodendroglial progenitors, and in neurons and protoplasmic astrocytes of late-term cultures. Basic FGF treatment of the progeny of NSCs increased the proliferative rate of precursors and the number of oligodendrocytes generated, whereas the number of differentiating neurons was significantly reduced. Together these data provide evidence that FGFs modulate the development of EGF-expanded NSCs, and that this is at least partly determined by a cell lineage-specific expression of multiple FGFRs.
