Mouse Blood-brain barrier (EM)
| Fig. 11 Regions of overlap between neighboring endothelial cells, illustrating range of variation in structure of the intercellular cleft. In Fig. 11, the cleft is obliterated by a tight junction (arrow) extending throughout most of its length. The region of the intercellular cleft indicated by the arrow in Fig. 11 is shown in inset at higher magnification to illustrate that the total width of the tight junc- tion (between arrows at right) is less than twice the width of the adjacent plasma membrane (between arrows at left). | Fig. 12 Astrocytic end feet (A) lying between a myelinated axon and the basement lamina of the vascular endothelium. A cleft between the astrocytic end feet extends from the basement lamina to a perivascular myelinated axon and appears open except near the blood vessel where it is invaded by some basement lamina material. |
