Immunological characterization of multipotent mesenchymal stromal cells--The International Society for Cellular Therapy (ISCT) working proposal.

Cultured mesenchymal stromal cells (MSCs) possess immune regulatory properties and are already used for clinical purposes, although preclinical data (both in vitro and in vivo in animal models) are not always homogeneous and unequivocal. However, the various MSC-based clinical approaches to treat immunological diseases would be significantly validated and strengthened by using standardized immune assays aimed at obtaining shared, reproducible and consistent data. Thus, the MSC Committee of the International Society for Cellular Therapy has decided to put forward for general discussion a working proposal for a standardized approach based on a critical view of literature data.
