The bZIP transcription factor CCAAT enhancer-binding protein β (C/EBPβ) exhibits neurogenic, neuritogenic, and pro-survival effects in the central nervous system. Here, we show that C/EBPβ regulates neural stem cell (NSC) expansion and vascular endothelial growth factor A (VEGF-A) level by acting on a C/EBPβ-responsive element within the Vegf-a promoter. As predicted, C/EBPβ depletion reduced VEGF-A production, NSC number, and average neurosphere size in proliferating cultures. Conversely, deletion of the C/EBPβ repressor CHOP-10 induced C/EBPβ and VEGF-A expression, while stimulating NSC expansion. These data highlight the role of C/EBPβ in regulating VEGF-A production and the growth of NSCs and suggest CHOP-dependent antagonism of C/EBPβ may function as a transcriptional rheostat linking stress-associated cues with stem cell quiescence among other pathological responses affecting the neurogenic niche. CCAAT enhancer-binding protein β (C/EBPβ) acts on cis elements within the vascular endothelial growth factor A (Vegf-a) promoter and increases VEGF-A expression. In proliferating neural stem cell (NSC) cultures, C/EBPβ enhances VEGF-A production and secretion, as well as NSC number and neurosphere size. Conversely, C/EBP homologous protein-10 (CHOP-10) inhibits C/EBPβ and VEGF-A expression, while suppressing NSC expansion.
