FIG. 6.

Cells were grown in triplicates in 12-well plates with 30,000 cells per well in media (FBS) containing growth factors for 2 days. Fresh charcoal media and ligands were replaced in 2-day intervals. On the seventh day, cell proliferation count was determined using the Coulter Counter. The relative intensities are, compared to Cs, displayed as the mean ± SEM. The sample sizes came from five density measurements per group. The asterisk indicates significant difference with the control at p < 0.05 (Kruskal–Wallis test followed by post hoc analysis using Mann–Whitney U-test).
