摘要: Cancer metastasis is the deadliest event in tumorigenesis. Despite extensive
research, there are still unsolved challenges regarding early metastasis detection and targeting
strategies. Extracellular vesicles (EVs) and their impact on tumorigenic-related
events are in the eye of current investigations. EVs represent a plethora of biomarkers
and information, and they are considered key determinants in tumor progression and for
tumor prognosis and monitoring. EVs are one of the key mediators for inter-cellular
communications between tumor cells and their nearby stroma. They are involved in different
steps of metastasis from invasion toward formation of pre-metastatic niches
(PMNs), and final growth and colonization of tumor cells in desired organ/s of the target.
Membrane components of EVs and their cargo can be traced for the identification of
tumor metastasis, and their targeting is a promising strategy in cancer therapy. In this review,
we aimed to discuss the current understanding of EV-based metastatic predilection
in cancer, providing updated information about EV involvement in different metastatic
steps and suggesting some strategies to hamper this devastating condition.
