About this Research Topic

Background

This Research Topic is Volume II of a series. The previous volume, which has attracted 151 authors can be found here: Advanced Therapies for Cardiac Regeneration.

Myocardial infarction is caused by the obstruction of coronary arteries, resulting in the death of approximately 1 billion cardiomyocytes in the left ventricle within a few hours, acute inflammation, and degradation of the cardiac extracellular matrix, with the formation of a fibrotic scar. Fibrotic tissue is mechanically stiffer than healthy cardiac tissue, it is mainly populated by cardiac fibroblasts, and lacks beating cardiomyocytes. The cardiac scar may undergo continuous remodeling, leading to left ventricle dilation and progressive congestive heart failure, which is the current leading cause of mortality and morbidity in the industrialized world. The only standard therapy addressing the irreversible loss of functional cardiomyocytes is heart transplantation, which however is limited by donor loss and the need for life-long immunosuppression. An ideal cardiac regenerative medicine strategy should replace lost cardiomyocytes and recover myocardial functional contractility.

To this purpose, cell-based regenerative therapies and tissue-engineered scaffolds/patches have been investigated for years, however, their success has been limited by the poor grafting, survival, and integration of the implanted cells into the infarcted tissue and the limited endogenous regenerative potential of the adult heart. Hence, the regeneration of a damaged heart still remains a major clinical challenge with a deep social and economic impact. Outcomes of cell therapies could be improved through the local implantation of cell-populated scaffolds or hydrogels reaching higher cell retention, survival, and integration with the host tissue. Electrically conductive biomaterials and stretchable patches, based on elastomeric materials and/or specific geometrical patterns, are also attracting growing interest, for their ability to trigger cardiomyocyte maturation and electromechanical coupling with the host tissue. Other cardiac regeneration strategies include cell reprogramming approaches, which are aimed at directly converting cardiac fibroblasts into induced cardiomyocytes or at stimulating cardiomyocyte proliferation. Over the last decade, the traditional cardiac tissue engineering strategies have also been translated towards the design of in vitro bioengineered cardiac tissue models for basic research purposes, toxicity assessment, innovative therapies evaluation, and drug screening.

This Research Topic is aimed at the publication of interdisciplinary studies on advanced therapies for cardiac regeneration. Through a collection of original papers and review articles, this Research Topic aims to collect the latest state-of-the-art ideas, concepts, findings, achievements, and future projections and promote awareness of these multidisciplinary studies, thereby encouraging bridging the gap between medicine, pharmacy, material sciences, biomechanics and engineering for research collaboration across fields to address cardiac regeneration. Clinicians and researchers are invited to contribute with their original evidence-based articles, as well as critical literature review manuscripts, summarizing the most recent and exciting innovative developments.

Potential topics include, but are not limited to, the following:
• Basic studies on cell behavior in pathological and healthy cardiac tissue
• Cell therapies for cardiac regeneration
• Scaffolds for cardiac tissue engineering
• Injectable hydrogels for cardiac tissue engineering
• Direct cardiac reprogramming
• Biomaterials in cell differentiation and/or reprogramming
• In vitro tissue-engineering models of healthy and pathological cardiac tissue
• Nanomedicine for gene therapy in cardiac regeneration
• Drug release for cardiac regeneration
• New microfluidic platforms for cardiac differentiation/reprogramming
• Microfluidic models of cardiac tissue

The Research Topic is organized in the framework of the project BIORECAR (grant number: 772168; http://www.biorecar.polito.it/index.html)

Frequently asked questions

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

     

  • 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.

  • Yes, we would love to hear your ideas for a topic. Most of our Research Topics are community-led and suggested by researchers in the field. Our in-house editorial team will contact you to talk about your idea and whether you’d like to edit the topic. If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.
