Clinically detectable metastases represent an ultimate consequence of the metastatic cascade that consists of distinct processes including tumor cell invasion, dissemination, metastatic niche formation, and re-growth into a detectable metastatic mass. Although angiogenesis is known to promote tumor growth, its role in facilitating early events of the metastatic cascade remains poorly understood. We have recently developed a zebrafish tumor model that enables us to study involvement of pathological angiogenesis in tumor invasion, dissemination and metastasis. This non-invasive in vivo model allows detection of single malignant cell dissemination under both normoxia and hypoxia. Further, hypoxia-induced VEGF significantly facilitates tumor cell invasion and dissemination. These findings demonstrate that VEGF-induced pathological angiogenesis is essential for tumor dissemination and further corroborates potentially beneficial effects of clinically ongoing anti-VEGF drugs for the treatment of various malignancies.
