Messenger-RNA expression levels in single-cell and cocultured PBMC. PSC alone (without PSC; white bars) and cocultured (with PSC; black bars) PBMC were analyzed by quantitative RT-PCR using primers for IL-6, MCP-1 and TGFbeta. Results are expressed as copies per 10 k copies of cyclophilin B (cpb). *p < 0.05 as assessed using the Mann-Whitney U test.
