About this Research Topic

Background

Extracellular matrix (ECM) is an active, critical regulator of cell behavior and the dynamics of extracellular microenvironments. ECM composition and organization play a key role in development, tissue homeostasis and regeneration, but can also underpin disease processes including tumor development, cancer progression, fibrosis and inflammatory disease. Bioengineering approaches have been developed to modulate physicochemical properties of the ECM and to recreate synthetic analogues, which can help define the impact of ECM via cell-matrix interactions. Recent 3D/4D printing technologies attempt to recreate these microenvironments with enhanced spatiotemporal controls. However, analysis of these complex inputs and responses in heterogeneous environments requires systematic approaches. Beyond conventional imaging, non-linear optics, computational methods, and systems biology approaches can define diverse and complex environmental signals that maintain and perturb ECM microenvironments. In this regard, computational and informatics approaches will be exceptionally helpful to process such data that possess inherently multivariate nature. Analysis of big data using machine learning and deep learning technology is an emerging area, and application of these approaches to understanding ECM microenvironments has the potential to deliver transformative information in a broad range of fields.
In this Research Topic, we encourage participation from diverse research groups working on ECM microenvironments with variety of engineering, imaging and computational technologies. We welcome Original Research, Methods, Review, Perspective and Mini Review articles. Primary areas will include tissue engineering, ECM modeling with in vitro, ex vivo and in vivo technology, bioinformatics, advanced imaging technology, biomaterials, deep learning, and stem cell bioengineering. Some of these areas are well-developed and already have shown to be critical to understand tissue homeostasis and disease conditions. Other areas are emerging with the aid of computational power and availability of ample data. This Research Topic provides an opportunity for researchers with interests in engineering and imaging ECM to share their new data, ideas and approaches in this rapidly developing interdisciplinary field.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

• Who leads a Research Topic? 

  A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

  The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

• What is the role of a topic editor?

  As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

   

  You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

• What support will I receive when editing a new Research Topic? 

  As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).
