Amino acid deletions at positions 893 and 894 of cytotoxin-associated gene A protein affect Helicobacter pylori gastric epithelial cell interactions

Figure 4 Induction of AGS cells hummingbird phenotype. A: The percentage of hummingbird cells at 12 hours and 24 hours after transfection into AGS. The number of hummingbird cells was quantitated in triplicate in 5 random fields and the results were mean ± SD of three independent experiments. Errors bars represent standard errors of the means. ^aP < 0.05, ^bP < 0.01; B: Representative micrographs of transfected AGS cells as indicated (100 ×). 1 and 2 represented cell morphology at 12 hours and 24 hours after transfection, respectively. Scale bar = 100 μm.
