Figure 8

Semi- and ultra-thin sections of BL2B95 tumors. A) At approximately 5 mm distance from the solid tumor, some lymphoma cells are found in the CAM stroma. The CAM lymphatics (L) are completely filled with tumor cells. Bar = 300 μm. B - D) Higher magnification of the specimen in A). B, C) Semi-thin sections. The lymphatics (L) are completely filled with tumor cells. Bar = 30 μm in B, and 40 μm in C. D) Ultra-thin section showing lymphatic endothelium (LE) and tumor cells, which fill the vessel completely. Two leukocytes (arrowheads) are visible. One is in contact with a dying lymphoma cell (asterisk), as seen by the heterochromatin condensation in the periphery of the nucleus. Bar = 10 μm.
