Vascular endothelial growth factor (VEGF) isoform regulation of early forebrain development

► VEGF isoforms are differentially expressed in the developing mouse forebrain. ► Expression of VEGF120 isoform results in reduced proliferation in neuroepithelium. ► The basal progenitor population is unaltered in VEGF120 mice. ► Fewer symmetric versus asymmetric mitotic spindle divisions occur in VEGF120 mice.
