Special Issue Information

Dear Colleagues,

In recent decades, the need for alternative treatments for various diseases has prompted scientists to focus their attention on cell-based therapies and regenerative medicine. Mesenchymal stromal cells (MSCs) may be isolated from various anatomical sites, including bone marrow, adipose tissue, and the umbilical cord. These cells exhibit potent paracrine properties based on the release of different mediators, including regulatory factors, chemokines, cytokines, growth factors, and nucleic acids, that can be secreted or packaged into extracellular vesicles, and are also implicated in the therapeutic effects of MSCs. The process underlying these effects likely involves the migration and homing of MSCs toward inflamed and injured tissue. During tissue healing, MSCs modulate immune responses and support tissue repair and regeneration. Advances in separation, culture, expansion, and biobanking techniques for MSCs have enabled their large-scale clinical application. This progress has been accompanied by the rapid clinical utilization of MSCs in regenerative and immunomodulatory approaches to treat or prevent diseases.

The purpose of this Special Issue is to bring together contributions from specialists in cellular biology, stem cells, immunology, and bioengineering on the latest advances in the understanding of the mechanisms of action underlying the therapeutic effect of MSCs, in clinical applications of MSCs for the treatment of inflammatory and degenerative diseases/conditions, in developing bioengineering/priming solutions to enhance MSC effectiveness, and in establishing bioprocessing platforms for large-scale MSC production for clinical applications.

We welcome the submission of original research and review articles that cover, but are not limited to, the following topics:

  • Cellular and molecular mechanisms underlying the therapeutic effects of MSCs;
  • Interactions between MSCs and other cell types in vitro and in vivo;
  • Bioengineering/priming solutions to boost the functions of MSCs;
  • Bioengineering strategies for improving the administration of MSCs;
  • Therapeutic applications of MSCs for inflammatory and degenerative diseases;
  • Establishment of bioprocessing platforms for MSC production in a large scale for clinical applications;
  • Cellular and molecular changes induced in MSCs during the bioprocess that may compromise their therapeutic potential;
  • MSC-derived products (e.g., soluble factors and extracellular vesicles) as mediators of immunomodulation and tissue repair.

Mesenchymal stem cells (MSCs) have gained recognition as a highly versatile and promising cell source for repopulating bioengineered scaffolds due to their inherent capacity to differentiate into multiple cell types. However, MSC implantation techniques have often yielded inconsistent clinical results, underscoring the need for advanced approaches to enhance their therapeutic efficacy. Recent developments in three-dimensional (3D) bioengineered scaffolds have provided a significant breakthrough by closely mimicking the in vivo environment, addressing the limitations of traditional two-dimensional (2D) cell cultures. Among these, nanofibrous scaffolds have proven particularly effective, offering an optimal 3D framework, growth-permissive substrates, and the delivery of trophic factors crucial for MSC survival and regeneration. Furthermore, the selection of appropriate biomaterials can amplify the paracrine effects of MSCs, promoting both proliferation and targeted differentiation. The synergistic combination of MSCs with nanofibrous scaffolds has demonstrated remarkable potential in achieving repair, regeneration, and tissue-specific differentiation with enhanced safety and efficacy, paving the way for routine clinical applications. In this review, we examine the most recent studies (2013–2023) that explore the combined use of MSCs and nanofibrous scaffolds for differentiation into cardiogenic, epithelial, myogenic, tendon, and vascular cell lineages. Using PubMed, we identified and analyzed 275 relevant articles based on the search terms “Nanofibers”, “Electrospinning”, “Mesenchymal stem cells”, and “Differentiation”. This review highlights the critical advancements in the use of nanofibrous scaffolds as a platform for MSC differentiation and tissue regeneration. By summarizing key findings from the last decade, it provides valuable insights for researchers and clinicians aiming to optimize scaffold design, MSC integration, and translational applications. These insights could significantly influence future research directions and the development of more effective regenerative therapies. Full article
