Bovine aortic and microvascular endothelial cells showed good adhesion with spreading on fibronectin or collagen IV and to a lower extent on laminin. Recognition of native laminin was due to its long arm fragment E8 and was mediated by alpha 6 integrins as demonstrated by antibody inhibition. A considerably stronger, RGD-dependent interaction was observed with the isolated laminin short arm fragment P1 previously shown to represent a cryptic cell-binding site. No adhesion was observed with the heparin-binding fragment E3. In contrast, murine microvascular endothelial cells transformed by the polyoma middle T oncogene showed preferential adherence and spreading on laminin via its E8 cell-binding site and also showed adhesion to fragment E3. Attachment to laminin fragment P1 and to collagen IV was low or negative and was never followed by spreading. These data show that the transformation of microvascular endothelial cells, which give them the property to form hemangiomas, also leads to changes in cell adhesion to extracellular matrix proteins, particularly to laminin fragments.
