Cell migration is a tightly regulated phenomenon necessary for regular physiologic processes such as wound healing, immune response, embryonic development, growth, and regeneration [1–3]. Consequences of abnormal migratory behaviors include autoimmune diseases and metastasis during cancer progression [4, 5]. Described as one of the hallmarks of cancer, metastasis is a complex multistep process, and is responsible for 90% of cancer deaths in humans. A better understanding of the process of metastasis is of paramount importance in developing efficient cancer treatment therapies and drugs [6].
