Messenger-RNA expression levels in single-cell and cocultured PSC. PSC alone (without PBMC; white bars) and cocultured (with PBMC; black bars) PSC were analyzed by quantitative RT-PCR using primers for IL-6, MCP-1, IL-8 and TGFbeta (A) as well as for collagen1 and fibronectin (B). Results are expressed as copies per 10 k copies of cyclophilin B (cpb). *p < 0.05 as assessed using the Kruskal-Wallis test followed by Dunn's post-hoc test to compare single-cell PSC with cocultured PSC.
