Special Issue Information

Dear Colleagues,

Human mesenchymal stem cells (MSCs) are one of the most used stem cells for clinical applications. So far, MSCs have been used in over 1500 clinical trials to treat over 30 diseases. However, MSC applications are being greatly affected by several limitations, such as limited lifespan, gradual loss of MSC stemness during in vitro expansion, cell rejection during transplant etc. Extracellular vesicles (EVs), particularly exosomes, are small membrane-bound particles secreted by cells. EVs carry various bioactive molecules such as proteins, lipids, mRNAs, and miRNAs, which contribute to their therapeutic effects. MSC-derived EVs are considered to mediate many of the therapeutic effects previously attributed to MSCs themselves, offering a cell-free alternative in regenerative medicine. Due to the advantages of MSC-EVs in cell-free approaches, i.e., their scalability and safety, MSC-EVs have been used for anti-inflammatory effects, tissue repair, neurological disorders, and cancer therapy.

Advanced therapy using MSCs and MSC-EVs is an emerging field for enhanced regenerative medicine and cell-based/free therapy. These approaches leverage the biological properties of MSCs and their secreted EVs to treat various conditions, including tissue injuries, inflammation, and degenerative diseases.

This Special Issue of the International Journal of Molecular Sciences titled “Advanced Therapy Using Human Mesenchymal Stem Cells (MSCs) and MSC Extracellular Vesicles” will include a selection of scientific contributions aimed at presenting the development and applications using MSCs and MSC-EVs, including cell therapy, gene therapy, EV characterization/standardization and application, manufacturing and scale-up, and mechanistic understanding to address personalized and regenerative medicine approaches.

Original research, review articles, preclinical studies, short communications, and letters on all topics in these research fields are invited.

This Special Issue is now open for submissions. If you are interested in contributing your work, please send a tentative title or short abstract to the Guest Editor or Editorial Office.

Osteoarthritis (OA) is a degenerative joint disease with limited therapeutic options, where inflammation plays a critical role in disease progression. Extracellular vesicles (EV) derived from mesenchymal stromal cells (MSC) have shown potential as a therapeutic approach for OA by modulating inflammation and alleviating degenerative processes in the joint. This study evaluated the therapeutic effects for the treatment of OA of two types of EV—exosomes and matrix-bound nanovesicles (MBV)—both derived from the human umbilical cord MSC (UC-MSC) via differential ultracentrifugation. Different phenotypes of human monocyte-derived macrophages (MDM) were used to study the anti-inflammatory properties of EV in vitro, and the medial meniscectomy-induced rat model of knee osteoarthritis (MMx) was used in vivo. The study found that both EV reduced pro-inflammatory cytokines IL-6 and TNF-α in MDM. However, exosomes showed superior results, preserving the extracellular matrix (ECM) of hyaline cartilage, and reducing synovitis more effectively than MBVs. Additionally, exosomes downregulated inflammatory markers (TNF-α, iNOS) and increased Arg-1 expression in macrophages and synovial fibroblasts, indicating a stronger anti-inflammatory effect. These results suggest UC-MSC exosomes as a promising therapeutic option for OA, with the potential for modulating inflammation and promoting joint tissue regeneration. Full article
