The present study involved the isolation and characterization of canine tumor endothelial cells (TECs) from two malignancies. TECs were isolated using magnetic cell sorting following FITC labeling with UEA1 lectin, and they were characterized by measuring genetic and histopathological endothelial markers. Isolated TECs exhibited a cobblestone-like morphology and expressed both vascular endothelial growth factor receptor 2 (VEGFR2) and Von Willebrand factor (vWF). Further, both TECs and tumor cells derived from a seminoma exhibited increased C-X-C chemokine receptor type 7 (CXCR7) expression. However, CXCR7 expression was not detected in TECs and tumor cells derived from a hepatocellular carcinoma. Understanding TEC specific traits may be important in the development of more efficacious anti-angiogenic therapies that do not induce adverse effects.
