Fig. 4. Morphological changes in HeLa cells with heat-killed LAB strains grown at 25°C detected using confocal imaging. (A) Control, (B) LGG, (C) KU22001, (D) KU22002, and (E) KU22005. The red arrow shows the condensation or breakage of the nucleus of treated cells; white scale bar indicates 10 μm. LGG, Lacticaseibacillus rhamnosus GG; KU22001, Enterococcus faecium KU22001; KU22002, Enterococcus faecium KU22002; KU22005, Enterococcus faecium KU22005.
