Tumor cell morphology. Control vector (pcDNA plasmid and retroviral vector [RV]) and mesothelin overexpressing tumors harvested from mice (Fig. 6) were frozen, fixed, and stained with hematoxylin and eosin. Vector control tumors (left) show epithelial cobblestone morphology while mesothelin over-expressing tumor cells (right) show more spindle shaped morphology
