Vessels belonging to 5 microvascular units (arteriole-capillary-venule sequence) in the tenuissimus muscle of cat were identified in the EM by using a serial sectioning technique. Morphometric analyses were performed on the plasmalemmal vesicle population in 4 defined vessel segments: terminal arterioles, arteriolar 4th of capillaries, venular 4th of capillaries and postcapillary venules. The sizes and numbers of vesicles, classified as luminal, abluminal and free vesicles, were assessed. The abluminal vesicles were more numerous than the luminal ones in the same segment. There were markedly different patterns of vesiculation along the 5 microvascular units which may indicate endothelial transport function reactivity to unknown factors in the local microenvironment.
