FIG. 2.

Lung tumor characteristics 4 months after administration of AAV6 vectors encoding ENTV Env. Top left, hematoxylin and eosin stain showing adenocarcinoma (left) and adenoma (right) (×100 magnification). Top right, recognition of ENTV Env expression in tumors (brown stain) by a monoclonal antibody made against the SU domain of JSRV Env (×40). Bottom left, surfactant protein C antibodies stain tumor and alveolar type II cells (brown) but not airway cells (×100). Bottom right, CC-10 antibodies stain Clara cells (brown) in the airway but not tumor cells (×100). Images shown are from mouse 5-3 (Table 1). Antibody-stained sections were counterstained with methyl green.
