Rat Venular Microvessel Electron Micrograph

A Cross-section of a venular microvessel (VM) in rat mesentery. There are seven endothelial cell (EC) clefts, C1-C7, with all of the cleft exits covered by neighboring pericytes (PCs). PCs are immediately underneath ECs. There are two fibroblasts (fib.) outside PCs. The blowout shows C2 covered by a PC with a trapped microdomain (TM) of uniform thickness in between.

B An enlarged view showing a cleft exit covered by a PC, creating a TM of roughly uniform thickness except at the narrow exit.
