Generation of monoclonal antibodies directed against organ-specific endothelial cell surface determinantsDZ Zhu and BU Pauli Department of Pathology, Cornell University, College of Veterinary Medicine, Ithaca, New York 14853. Organ-specific determinants expressed on the luminal surface of vascular endothelia are often unstable when cells are removed from their normal tissue environment and grown in culture. Unspecific endothelial cells of large vessel origin [e.g., bovine aorta (BAEC)] can be modulated to express and preserve such determinants when they are grown on the extracellular matrix of the desired organ. Lung matrix- modulated BAEC were used here to generate MAb against lung-specific vascular endothelia. Immunization was accomplished with outside-out membrane vesicles obtained by incubating BAEC monolayers grown on lung matrix with a low-strength paraformaldehyde solution. In four of the six fusions performed, this active immunization was preceded by passive immunization with mouse antiserum directed against membrane vesicles from BAEC grown on plastic. Among the growing hybrids, 7.6% secreted MAb that bound efficiently to both BAEC grown on lung-derived matrix and BAEC grown on plastic, while 3.5% (50) secreted MAb that bound primarily to BAEC grown on lung matrix. The fusion data show that only a passive/active immunization protocol yielded MAb directed against lung-specific endothelia. For example, MAb 6D3 and 5F5 selectively recognized endothelia from small- and medium-sized venules of bovine lungs, but failed to react with endothelial cells in other organs and tissues.
