Figure 5. Representative fluorescence microscopy images of wild type (WT) C2C12 cells used to evaluate the efficiency of lipid mixing by analysis of redistribution of lipid probe (Dil) and content probe (CellTracker^TM Green).

Images of the cells after co-incubation of Dil-labeled cells with Cell Tracker^TM Green-labeled cells in the differentiation medium. Nuclei are stained by Hoechst. Arrow indicates an example of mononucleated cell co-labeled with Dil and CellTracker^TM Green. Arrowhead marks an example of a co-labeled syncytium. Scale bar = 50 μm.
