The use of horseradish peroxidase as a macromolecular tracer showed partial differences in paracellular and transcellular pathways of the net transendothelial protein transport related to the segmental belonging of microvessels. The most likely pathway of transport through precapillary arteriolar endothelium is poorly expressed vesicular transfer. High endothelial permeability in subepithelial and marginal capillary and postcapillary venule of intestinal villi for horseradish peroxidase, is mostly due to vesicular transport and open junctions. Transendothelial channels and fenestrations in exchange microvessel endothelius were marked by horseradish peroxidase.
