Fig. 2. Apoptosis of HeLa cells treated with heat-killed LAB strains grown at 25°C and 37°C determined using flow cytometry. (A) Representative Annexin V-FITC/PI staining for apoptosis. (B) Apoptotic rate (%). LGG, Lacticaseibacillus rhamnosus GG; KU22001, Enterococcus faecium KU22001; KU22002, Enterococcus faecium KU22002; KU22005, Enterococcus faecium KU22005. Results are presented as mean ± SD derived from three independent experiments. *p < 0.05, and **p < 0.01 compared with the control.
