Figure Lengend Snippet: Apoe deficiency increases neutral lipid accumulation in lipid-loaded BMDMs (A) Schematic overview of BMDM isolation and BODIPY 493/503 staining. Bone marrow cells were isolated from WT and Apoe −/− mice and differentiated into BMDMs with M-CSF for 7 days. (B–D) Representative flow cytometry histograms and quantification of BODIPY 493/503 signal in WT and Apoe −/− BMDMs under untreated conditions (B) , after OA treatment (200 μM, 24 h) (C) , and after oxLDL treatment (50 μg/mL, 24 h) (D) . BODIPY 493/503 fluorescence was quantified as background-subtracted median fluorescence intensity (ΔMedian MFI). Data are shown as mean ± SEM. n = 3 biological replicates per group. P values were calculated using unpaired two-tailed Welch’s t-tests. ns, not significant; ** P < 0.01 ; *** P < 0.001 . OA, oleic acid; oxLDL, oxidized low-density lipoprotein; M-CSF, macrophage colony-stimulating factor; BMDMs, bone marrow-derived macrophages.
