MSCs: Modulation of the Immune System

MSCs have a notable ability to modulate the immune response, particularly by inhibiting T-cell alloreactivity. This property is particularly beneficial in autoimmune conditions like Crohn's disease, where an overactive immune response contributes to inflammation and tissue damage. The safety profile of MSC therapy is favorable, with no reported acute toxicity or ectopic tissue formation, making it a viable option for patients​​.

‍

Durability of MSC Therapy Effects

A study examining the long-term effects of mesenchymal stem cells for treating fistulizing Crohn's disease found that the treatment response was durable at 12 months. This study, which included phase IB/IIA clinical trials for various fistula types associated with Crohn's disease, demonstrated significant and sustained clinical and radiographic healing in a substantial percentage of patients, underscoring the potential of MSC therapy as a safe and effective alternative treatment​​.

These findings underscore the potential of mesenchymal stem cell therapy as a novel and effective treatment modality for patients with Crohn's disease, offering hope for those with treatment-refractory conditions and complex fistulas.
