evidence that macromolecular transport across endothelial cells may be asymmetric , favoring movement from interstitium to lymph , is derived from 1 ) studies using isolated perfused lymphatics , 2 ) differential luminal and abluminal membrane staining with cationic stains , 3 ) the presence of charged microdomains on lymphatic endothelial cell surfaces revealed with macromolecules of different charges , and 4 ) studies on cultured monolayers of porcine arterial endothelial cells .
