Figure 1 In vitro reactivity to MSC measured before and after systemic MSC treatment, with each individual compared with himself/herself. Measured in MLC and with stimulation by PHA. No change in reactivity before and after treatment could be found.

Figure 2 Levels of IL-2 receptors in blood before and at weekly intervals after MSC treatment. Each individual compared with himself/herself. A significant decline in IL-2 receptors was found 1 week after MSC treatment.

Figure 3 Comparison of in vitro inhibition of patient PBMCs by MSC treatment in clinical responders and nonresponders. Measured in MLC and with stimulation by PHA. No correlation was found between in vitro results and clinical response.
