Impact of Helicobacter pylori on the healing process of the gastric barrier

Figure 5 Effect of Helicobacter pylori antigens on the fibroblast cell cycle profile. Fibroblasts were incubated for 24 h in RPMI-1640 medium alone or in the presence of bacterial antigens. The cell cycle profile was determined by propidium iodide (PI) staining and the analysis was performed by flow cytometry. The data represent the percentage of cells in each cycle phase of six experiments. Statistically significant differences are indicated as P < 0.05 vs untreated cells and included in DNA histograms.
