Whereas numerous preclinical studies demonstrated that blocking angiogenesis or lymphangiogenesis could inhibit tumor metastasis, the scarcity of highly selective targeting candidates hampers their translation to the clinic. We employed a new approach consisting of immuno-laser capture microdissection (i-LCM) and transcriptional profiling by means of microarrays in order to identify novel tumor-specific endothelial markers. By using short immunostainings prior to microdissection, specific identification of lymphatic (LECs) and blood (BECs) endothelial cells was allowed. For the subsequent gene expression profiling, a single round of the Ribo-Spia amplification method in combination with the Affymterix microarray platform was used. Comparison of gene expression profiles of tumor-associated and normal LECs resulted in the identification of differentially expressed genes in tumor-associated lymphatic vasculature.http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-15760http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-15760/samples/
