Little is known about the extrinsic signals regulating these processes, particularly in the midbrain. Fibroblast growth factor (Fgf) 15, the mouse ortholog of FGF19 and member of an atypical Fgf subfamily, is prominently expressed in the dorsolateral midbrain of the midgestational mouse embryo. In the absence of Fgf15, dorsal midbrain neural progenitors fail to exit the cell cycle and to generate the proper amount of postmitotic neurons. We show here that this is due to the altered expression of inhibitory/neurogenic and proneural/neuronal differentiation helix-loop-helix transcription factor (TF) genes. The expression of Id1, Id3, and Hes5 was strongly increased and ectopically expanded, whereas the expression of Ascl1 (Mash1), Neurog1 (Ngn1) and Neurog2 (Ngn2) was strongly decreased and transcription of Neurod1 (NeuroD) was completely abolished in the dorsolateral midbrain of Fgf15(-/-) mice. These abnormalities were not caused by the mis-expression of cell cycle regulatory proteins such as cyclin-dependent kinase inhibitors or retinoblastoma proteins. Furthermore, human FGF19 promotes cell cycle exit of murine dorsal neural progenitors in vitro. Therefore, our data suggest that Fgf15 is a crucial signaling molecule regulating the postmitotic transition of dorsal neural progenitors and thus the initiation and proper progression of dorsal midbrain neurogenesis in the mouse, by controlling the expression of neurogenic and proneural TFs."xsd:string |
