Figure 7

Structures with partial endothelial lining. (a) Structures with partial endothelial lining associated with the retraction of tumor cells from the underlying stroma: phenomenon of tumor stroma retraction (1), structures with partial endothelial lining (2), and lymphatic vessel with a large tumor embolus in the lumen (3). Immunoperoxidase staining with the antibodies to podoplanin, x200. (b) Structures with partial endothelial lining which were not associated with the retraction of tumor cells from the underlying stroma. Immunoperoxidase staining with the antibodies to podoplanin, x800.
