The mechanisms that control this sequential generation of neuronal and glial cell types from the same progenitor population are not well understood. Growth differentiation factor 11 (Gdf11) belongs to the TGF-β family of proteins and is expressed transiently in newly born neurons adjacent to the progenitor domain in the developing spinal cord. We examined the phenotypes of Gdf11(-/-) mouse embryos and found that without Gdf11, neuronal differentiation in the spinal cord progresses at a slower rate. Higher progenitor proliferation rate, along with a delay in gliogenesis, is also observed in Gdf11(-/-) spinal cord but only after the peak of Gdf11 expression, indicating that Gdf11 can cause long-lasting changes in progenitor properties. These changes can be preserved in vitro, as neurospheres derived from Gdf11(-/-) and wild-type littermates at a stage after, but not before the onset of Gdf11 expression, exhibit differences in proliferation and differentiation potential. Moreover, these changes in progenitor properties can be induced in vitro by the addition of Gdf11. We also demonstrate that the effects of Gdf11 on progenitor cells are associated with its ability to upregulate p57(Kip2) and p27(Kip1) while downregulating Pax6 expression. These results support a model in which Gdf11 secreted by newly born neurons in the developing spinal cord facilitates the temporal progression of neurogenesis by acting as a positive feedback signal on the progenitor cells to promote cell cycle exit and decrease proliferation ability, thus changing their differentiation potential."xsd:string |
