Cell-interaction and uptake studies of rhodamine-labeled docosahexaenoic acid-loaded liposomes (ω-Lipo) and control liposomes (C-Lipo) in RAW264.7 macrophages.
Notes: RAW264.7 murine macrophages were incubated for 4 hours at 37°C with rhodamine-labeled liposomes (0.125 mM total lipid; red). Cells were visualized with fluorescent microscopy (A and B) or by confocal microscopy (C and D). Blue staining represents cell nuclei. Scale bars= 20 µm.
