| abstractText | BACKGROUND: The brain vascular system arises from the perineural vascular plexus (PNVP) which sprouts radially into the neuroepithelium and subsequently branches off laterally to form a secondary plexus in the subventricular zone (SVZ), the subventricular vascular plexus (SVP). The process of SVP formation remains to be fully elucidated. We investigated the role of Foxc1 in early stage vascular formation in the ventral telencephalon. RESULTS: The Foxc1 loss of function mutant mouse, Foxc1(ch/ch) , showed enlarged telencephalon and hemorrhaging in the ventral telencephalon by embryonic day 11.0. The mutant demonstrated blood vessel dilation and aggregation of endothelial cells in the SVZ after the invasion of endothelial cells through the radial path, which lead to failure of SVP formation. During this early stage of vascular development, Foxc1 was expressed in endothelial cells and pericytes, as well as in cranial mesenchyme surrounding the neural tube. Correspondingly, abnormal deposition pattern of basement membrane proteins around the vessels and increased strong Vegfr2 staining dots were found in the aggregation sites. CONCLUSIONS: These observations reveal an essential role for Foxc1 in the early stage of vascular formation in the telencephalon. Developmental Dynamics 244:703-711, 2015.
