Fig 2. Antiapoptotic activity of the F7 fraction in H₂O₂-treated cells.

J774A.1 cells were preincubated with the F7 lipid fraction for 12 h. H₂O₂ was then added to the cells (112.5 μM). After 12 h, the TUNEL-positive cells were quantified and the results expressed as the mean ± standard deviation of triplicate experiments. (A) TUNEL staining of J774A.1 cells treated with the F7 lipid fraction. (B) Frequency of apoptosis. (*) According to Student’s t test, the difference between the lipid-treated cells and untreated cells (control) was significant (P < 0.05).
