Endothelial cells are intimately involved in a variety of biological processes such as inflammatory disorders, wound healing, and tumor invasion. The finding of endothelial heterogeneity in various tissues has led to major efforts to isolate and culture microvascular endothelial cells in human and animal tissue. In this report we have used phosphatidyl ethanolamine (PE)-labeled liposomes to fluorescently label the sheep lung microvasculature in situ. Using normotensive perfusion pressure, the PE-labeled liposomes did not extravasate into extravascular lung tissue. Mechanical and enzymatic digestion of the lung tissue demonstrated that the PE-labeled liposomes provided a stable label of the vascular lining cells during ex vivo processing. After digestion, the overwhelming majority of the fluorescent label appeared in cellular aggregates. Approximately 80% of these cells demonstrated an in vitro phenotype consistent with microvascular endothelium. A novel monoclonal antibody selective for sheep endothelial cells was developed to confirm the presence of lung endothelium in the fluorescently labeled cellular aggregates. We conclude that in situ fluorescence labeling of vascular lining cells provides an anatomic marker for relevant vascular lining cells and an opportunity to study these cells in vitro.
