Special Issue Information
Dear Colleagues,
Gravity has constantly influenced both physical and biological phenomena throughout all of Earth’s history. The gravitational field played a major role in shaping evolution when life moved from water to land, by influencing natural selection only by limiting the range of acceptable body sizes. Indeed, to counteract gravity, living organisms would need to develop systems to provide cell membrane rigidity, fluid flow regulation, and appropriate structural support and locomotion. However, gravity can influence in a more deep and subtle fashion the way cells and tissues behave and build themselves. Gravity represents an ‘inescapable’ constraint that obliges living beings to adopt only a few configurations among many others. By ‘removing’ the gravitational field, living structures will be free to recover more degrees of freedom, thus acquiring new phenotypes and new functions/properties. Microgravity provides an unexpected opportunity to study how physical cues may successfully drive several biological properties, by interacting with genomic and proteomic cues.
Therefore, it has been argued that the ultimate reason for human space exploration is precisely to enable us to discover ourselves. Controlled studies conducted in microgravity can advance our knowledge, providing amazing insights into the biological mechanism underlying physiology as well as many relevant diseases, such as cancer. Thereby, space-based investigations may serve as a novel paradigm for innovation in basic and applied science.
Potential topics include, but are not limited to:
- Direct and indirect mechanisms of gravity sensing by cells and tissues;
- Shape, cytoskeletal, and nucleoskeletal changes in microgravity;
- Changes in molecular pathways upon microgravity exposure;
- Cell fate commitment and differentiation in microgravity;
- How microgravity affects gene expression and gene regulatory circuits, including miRNAs;
- Experimental models in microgravity: from 2D to 3D cell/organoid cultures.

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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
