Expression of the described barrier inducing factors in the adult mouse brain. Representation of the available global expression data of barrier-inducing factors in the adult mouse brain. Note the minimal overlap but the rather distinct regional expression of the individual factors suggesting site-specific induction/maintenance cues for endothelial barrier properties in the CNS (SVZ subventricular zone, Shh sonic hedgehog, GPR124 G-protein-coupled receptor)
