FIG. 1.

Microarray confirmation by real-time quantitative–polymerase chain reaction (RQ-PCR). The increased expression of Nur77 and Nurr1 in migratory FBMSC compared with nonmigratory MSC was confirmed by RQ-PCR for Nur77 (left) and Nurr1 (middle). Bars depict the fold increase (mean±SD, n=3) of migratory FBMSC normalized to nonmigratory FBMSC. The third family member Nor1 (right) was confirmed not differentially expressed. *P≤0.05. FBMSC, fetal bone marrow mesenchymal stromal cells; MSC, mesenchymal stromal cells.
