Mesenchymal stem cells (MSCs) have gained significant attention in regenerative medicine due to their multipotent capabilities and unique immunomodulatory properties. They can differentiate into various cell types and modulate immune responses, making them a promising tool for treating a wide array of diseases. This article delves into the immunological effects of MSCs and explores their applications in healthcare, referencing key studies on their safety, efficacy, and therapeutic mechanisms.
Mesenchymal stem cells (MSCs) can enhance the immune system by boosting immune responses. MSCs secrete bioactive molecules like interleukin-10 (IL-10) and transforming growth factor-beta (TGF-β), which support immune cell activation and proliferation. These properties collectively elevate the immune system, providing therapeutic potential for various immune-related conditions.
MSCs also influence dendritic cells (DCs), crucial for antigen presentation and initiating immune responses. They can induce a tolerogenic phenotype in DCs, reducing their ability to stimulate effector T cells and thereby dampening immune responses. In the study “Mesenchymal stem cells and immunomodulation: current status and future prospects”, scientists also elaborate on how MSCs can alter DC function to promote immune tolerance.

responses through their ability to influence the development of regulatory T cells (Tregs). This interaction helps in creating a more tolerant immune environment, which is beneficial for managing autoimmune diseases, improving transplant outcomes, and controlling inflammation.
Due to their immunomodulatory properties, MSCs are being explored for the treatment of autoimmune diseases such as rheumatoid arthritis, multiple sclerosis, and systemic lupus erythematosus. The aforementioned study on MSC transplantation in multiple sclerosis and amyotrophic lateral sclerosis patients highlighted the potential of MSCs to reduce disease severity and improve clinical outcomes by modulating the immune system.
MSCs have shown promise in treating severe COVID-19 by modulating immune responses and reducing inflammation. A study by researchers at The University of Hong Kong proved that MSC therapy led to significant improvements in COVID-19 patients, likely due to the cells’ ability to modulate the immune system and reduce the cytokine storm associated with severe cases.
