Special Issue Information
Dear Colleagues,
Research in the past several years has firmly established the importance of extracellular vesicles, particularly exosomes, as mediators of cell-to-cell communications within the tumor microenvironment. Acting as cargos, these vesicles shuttle critical molecules, including, proteins and RNA, from one cell to another, thus playing an important role in cellular cross talk. The delivery of cargo contents to recipient cells influences many fundamental physiological processes affecting growth, proliferation, apoptosis, cell cycle and response to therapies. Cancer metastasis is a major reason for cancer-associated mortality, and the role of extracellular vesicles, particularly, exosomes, in cancer metastasis is increasingly being realized. Mediating the cellular cross talk, exosomes deliver pro-metastatic factors that facilitate increased migration and invasion of tumor cells resulting in increased metastasis. The cargo can also consist of factors that mitigate the effects of anti-metastatic machinery. Additionally, in a true bi-directional cross talk, exosomes from tumor cells can ‘transform’ the cells in their immediate vicinity, such as fibroblasts, immune cells, etc., to turn pro-tumorigenic, which, in turn, communicate back with tumor cells, through exosomes, thus supporting metastasis. This Special Issue focuses on the role of extracellular vesicles in cellular cross talk leading to the alteration of the metastatic potential of tumor cells, which can potentially open up new avenues for the targeted therapy of metastatic cancers.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cells is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
