Ssays with pooled donor Tcells have already been proposed . In contrast, our information indicate that measurement of individual patient Tcell response to MSCs may be extra relevant in assessment of efficiency of MSC therapy. Determined by the correlation of MSC metabolism with their immunosuppressive potential, we suggest that MSC functionality could be predicted via metabolic measurements for instance lactate acid production or oxygen consumption after patient PBMC and donor MSC coculture. Taken collectively, our findings point to a feasible and informative potency assay that considers interindividual variations within the interaction of MSCs with patient immune effector cells.Conclusion Our data pave the way for an individualized potency assay for donor MSC and recipient Tcell interaction based on metabolic measurements. Enhancement of Tcell suppressive function by means of VPA supports the notion that the immunosuppressive activity of MSCs may be further enhanced invitro and potentially invivo. No matter whether metabolic parameters could possibly be useful to predict the efficacy of MSC therapy invivo needs to be determined in potential clinical trials.

In contrast, our data indicate that measurement of individual patient Tcell response to MSCs could be additional relevant in assessment of efficiency of MSC therapy. Depending on the correlation of MSC metabolism with their immunosuppressive prospective, we recommend that MSC functionality is often predicted by way of metabolic measurements including lactate acid production or oxygen consumption soon after patient PBMC and donor MSC coculture. Taken together, our findings point to a feasible and informative potency assay that considers interindividual variations within the interaction of MSCs with patient immune effector cells.Conclusion Our data pave the way for an individualized potency assay for donor MSC and recipient Tcell interaction depending on metabolic measurements.
