Figure 3 Number of cell–cell junctions staining strongly for β‐catenin (out of 200 counted), for HT29 cells untreated and cocultured with Helicobacter pylori strains 60190 (pathogenic) and Tx30a (non‐pathogenic). Coculture was carried out for 24 h with a bacteria:cell ratio of 100:1. Bar shows mean (SEM) of 5 experiment. *60190 versus untreated, p<0.05, t test.
