Blood brain barrier localization in rat brain, and microvessels isolated from rats.

<p>Cartoon representation of the lateral, 3^rd, 4^th ventricle choroid plexuses (LV CP, 3^rd V CP and 4^thV CP, respectively) and microvessels (MVs) localization in rat brain (A). Representative microvessels freshly isolated from rat brains. Freshly isolate MVs in 0.1% albumin in Krebbs-Ringer buffer were placed on a microscope slide and directly observed by phase contrast microscopy: In B scale bar 100 µm; in C, D, E, F and G scale bar 25 µm. P: post-natal age in days. jj: hyperbilirubinemic rats; Jj: controls.
