HepG2 and AML12 cells were first pretreated with FFA as described above. After three
washes using PBS, the cells were stained for 15 min after fixation with 4% formaldehyde
using 0.05 μg/ml
Nile red solution (Solarbio). The cell nuclei were stained using 496
diamidino-2-phenylindole (DAPI, Yeasen). The microscopic pictures were captured using an
electron microscope (Zeiss).
