Advancing Retinal Regeneration: The Role of Stem Cells in Therapy and Innovation

About this Research Topic

Background

The retina is a vital component of the visual system, responsible for converting light into neural signals. Retinal diseases such as age-related macular degeneration, retinitis pigmentosa, and diabetic retinopathy can lead to irreversible vision loss, presenting significant challenges for affected individuals and healthcare systems. Despite advances in medical and surgical interventions, the restoration of retinal function remains elusive. However, the field of regenerative medicine, including cell and gene therapy, offers promising avenues for retinal regeneration. Gene therapy can augment the absence of a functional gene or even be used to employ gene editing techniques to prevent or reverse vision loss. Retinal organoids that are derived from pluripotent stem cells provide a source of differentiated cell populations that can replace damaged retinal cells and thereby restore retinal architecture and function. In some cases, stem cells and gene therapy approaches provide platforms for drug discovery and identification of new drug targets to treat retinal degenerative diseases.

This Research Topic focuses on the latest advances in retinal regeneration through stem cell therapy and related innovations. By collecting different article types, this collection aims to foster an in-depth understanding of current challenges, novel methodologies, and future directions in the field of retinal regeneration.

Areas to be covered might include, but are not limited to:

o Stem Cell Sources and Differentiation: Exploration of various stem cell types, including embryonic stem cells, induced pluripotent stem cells, and adult stem cells, in retinal regeneration. Comparative studies on the differentiation capabilities and efficiency of different stem cell types into retinal cell lineages and retinal organoids.

o Gene Therapy: Novel vector designs, non-viral vectors, ex-vivo gene therapy, large animal models, human trials. This would include only cutting-edge technologies and not articles using existing vectors to treat mouse models of human disease.

o Innovative Delivery Systems: Development of bioengineering and nanotechnology-based approaches for optimizing stem cell and gene therapy delivery to the retina. Examination of scaffolds, hydrogels, and biomimetic materials designed to enhance cell survival, integration, and function.

o Retinal Microenvironment and Integration: Studies focusing on the retinal microenvironment's role in stem cell survival and integration. Insights into the adaptation and integration of stem cells within the existing retinal tissue.

o Applications of Gene Editing and Advanced Techniques: Utilization of gene editing tools, such as CRISPR/Cas9, to enhance stem cell functionality and safety. Innovative techniques to improve the precision and effectiveness of stem cell therapies in retinal regeneration.

o Use of gene transfer and stem cells in retinal drug discovery: Use of stem cells, organoids, and gene transfer to perform drug screening in vitro and in novel animal models. Cell-based pre-clinical assays, in-process and release assays, and safety studies.

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?
