Cell–Microenvironment Crosstalk, Models, and Molecular Mechanisms in Rhabdomyosarcoma: Current and Future Perspectives

Dear Colleagues,

It is with great pleasure and enthusiasm that we present to you this Special Issue of Medical Sciences. This issue aims at investigating the latest aspects under study to unveil the complexity of Rhabdomyosarcoma. The prognosis of this pediatric disease has improved significantly in recent years, but the outcome of patients with metastatic or refractory RMS remains dismal. Therefore, new treatment options targeting both malignant tumors and the context in which they live are paramount. Malignant cells do not act alone in cancer progression but need enduring interactions and crosstalk with supporting cell types and extracellular matrix components (ECM) that form the tumor microenvironment. The former includes cancer-associated fibroblasts (CAFs), myofibroblasts, and other cells, generally known as stromal cells. Generally, in tumors, CAFs exhibit enhanced proliferation and are responsible for the production and deposition of soluble and insoluble extracellular matrix molecules, such as collagens, structural proteoglycans, proteolytic enzymes, and growth factors. Soluble molecules present in close proximity to tumor cells bind to membrane receptors and initiate intracellular signaling cascades necessary to sustain proliferation, angiogenesis, and initiation of invasion and metastasis.

In this view, the present Special Issue aims to collect new aspects that are under exploration on the rhabdomyosarcoma microenvironment and tumor progression, considering the following aspects:

1. The microenvironment;
2. The immunoenvironment;
3. Extracellular vesicles;
4. Models to study rhabdomyosarcoma progression.

We look forward to receiving your contributions summarizing or explaining your research to this Special Issue.

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 250 words) can be sent to the Editorial Office for assessment.

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. Medical Sciences is an international peer-reviewed open access quarterly 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 1600 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.
