Special Issue Information
Dear Colleagues,
MSCs (mesenchymal stem/stromal cells) are found in practically all tissues and play a role in regeneration and homeostasis. They have the ability to self-renew and activate multipotency when stimulated by biochemical signals. The MSC secretome or MSC-derived extracellular vesicles (exosomes and microvesicles, EVs) have been hypothesized as a more important biological mechanism contributing to their function than their differentiation capacity. EVs play a role in cell-to-cell communication, cell signaling, and changing cell or tissue metabolism at the local or global level. MSC-derived exosomes contain, e.g., cytokines and growth factors, signaling lipids, mRNAs, and regulatory miRNAs.
The contents of MSC exosomes are dynamic, influenced by the MSC tissue of origin, its activity, and its immediate intercellular neighbors. Thus, when MSCs are grown alongside tumor cells or in the in vivo tumor microenvironment, the exosome concentration appears to be altered. MSCs can directly donate mitochondria to recover from cell injury and rescue mitochondrial damage-induced tissue degeneration. This could promote cancer growth and spread by promoting mitochondrial exchange between cancer cells and adjacent stromal cells. A growing body of evidence implies that physical stimulation has a role in MSC development.
We aim to highlight new areas of research related to MSC involvement in niche-specific development, tissue homeostasis, and function, with emphasis on the molecular level. This research will open the way for deciphering the molecular mysteries of MSCs, as well as for novel therapeutic modalities.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
