New NCI-N87-derived human gastric epithelial line after human telomerase catalytic subunit over-expression

Figure 7 Usefulness of the NCI-hTERT-CL6 cell line for in vitro infection assays with Helicobacter pylori. A: Viability in percentage of the cells when grown in a microaerobic environment (bacterial growth conditions) for 48 h compared to those grown at standard atmosphere (taken as 100%). Bars and respective error bars are mean ± SD of the values at each condition for twelve observations; B: IL8 secretion by NCI-hTERT-CL6 cells upon infection with the Helicobacter pylori (H. pylori) strain 417 (virulent strain) or the respective double-mutant for homB gene strain (strain 417DM) (less virulent strain), compared to uninfected cells. Bars are values obtained from one observation.
