Special Issue Information
Dear Colleagues,
Cancer development is a multistep process characterized by genetic and epigenetic alterations during tumor initiation and progression. The stromal microenvironment is important in maintaining normal tissue homeostasis or promoting tumor development. A plethora of immune cells (i.e., lymphocytes, macrophages, mast cells, monocytes, myeloid-derived suppressor cells, dendritic cells, neutrophils, eosinophils, natural killer (NK) and natural killer T (NKT) cells are components of cancer microenvironment. In the organs and tissues in contact with the external environment as skin and gastrointestinal system, the role of immune stromal cells is to defend the organism from pathogenic insults including cancers cells. Immune stromal cells density is increased in cancer and there is a correlation with angiogenesis, the number of metastatic lymph nodes and the survival of these patients. These cells exert a pro-tumorigenic role in cancer through the release of classical and non classical angiogenic (VEGF-A, CXCL-8, MMP-9, Tryptase, Chymase) and lymphangiogenic factors (VEGF-C, VEGF-F and PDPN). These cells express also the programmed death ligands (PD-L1 and PD-L2) which are relevant as immune checkpoints in cancer. Several clinical undergoing trials targeting immune checkpoints could be an innovative therapeutic strategy in cancer. Elucidation of the role of subsets of cells in different human cancers will demand studies of increasing complexity beyond those assessing merely cell density and micro-localization. The aim of this special issue is to evaluate from molecular biology to immunohistochemical analysis, specific immune stromal cells in tumor microenvironment, correlating these cells and their release factors with neo-angiogenesis and lymphangiogenesis, and investigating their role as possible novel biomarkers and new therapeutic strategies.

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. Biomedicines is an international peer-reviewed open access monthly 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 2600 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.
