Using confocal laser scanning microscopy we studied sections of the T24B, a human bladder carcinoma, grown in C.B.-17 scid/scid or NMRI nu/nu mice in order to examine the relationship between tumor tissue and tumor vessels. Tumor cells were labelled with FITC-anti-cytokeratin and blood vessel endothelia with Cy3-labelled BS-I lectin. In contrast to our expectation, no major leaks in the endothelial lining of blood vessels were observed. We are looking for a suitable marker for mouse lymphatics in order to investigate their possible role.
