There is an emerging understanding of the importance of the vascular system within stem cell niches. Here we examine whether neural stem cells (NSCs) in the adult subventricular zone (SVZ) lie close to blood vessels, using 3-dimensional wholemounts, confocal microscopy and automated computer-based image quantification. We found that the SVZ contains a rich plexus of blood vessels that snake along and within neuroblast chains. Cells expressing stem cell markers, including GFAP, and proliferation markers, are closely apposed to the laminin-containing extracellular matrix (ECM) surrounding vascular endothelial cells. Apical GFAP+ cells are admixed within the ependymal layer and some span between the ventricle and blood vessels, occupying a specialized microenvironment. Adult SVZ progenitor cells express the laminin receptor alpha6beta1 integrin, and blocking this inhibits their adhesion to endothelial cells, altering their position and proliferation in vivo, indicating it plays a functional role in binding SVZ stem cells within the vascular niche.
