MSC clinical use and therapeutic mechanisms

Mesenchymal stromal/stem cells (MSCs) are multipotent adult cells which can be isolated from several adult tissues. MSCs have been explored in tissue repair due to their differentiation potential into mesenchymal lineages. Besides their regenerative capacities, MSCs also display immunomodulatory functions and with very low immunogenicity. For these reasons, MSCs are emerging as an interesting and promising immunosuppressive therapeutic agent in severe immunological complications such as for instance graft-versus-host disease. MSCs are also being explored in cell-based therapies for different tissue injuries.

We are engaged in several clinical research collaborations exploring the use of allogeneic bone marrow-derived mesenchymal stromal cells (MSCs) in refractory graft-versus-host disease, a life-threatening complication after stem cell transplantations. We are also interested in elucidating the therapeutic mechanisms of MSCs, especially in immunomodulation. We are also interested in potential new clinical indications for MSCs such as autoimmune diseases, stroke, cartilage defects and colitis in active collaboration with experts in the field.
The frequency of MSCs is extremely low in adult tissues (for instance 0.001–0.01% of all nucleated cells in the bone marrow) and an ex vivo expansion (cell culture) step is thus inevitable to obtain sufficient cell numbers for research or clinical purposes. We are engaged in research concerning clinical MSC manufacturing, especially the development of xenofree (animal-component free) cell culture methods. A GMP- and clinically-compliant cell culture method has been developed in-house for bone marrow-derived MSCs. We are currently investigating different strategies to improve our current manufacturing method and the potential impact of cell freezing.
