Fig. 4

Representative JC-1 staining of gill filament visualizing areas with different mitochondrial membrane potential (Δψm). a1: overview of filament structure, a2: corresponding transmission image. b: fluorescence intensity ratio (aggregate/red: monomer/green) across a filament transect. Black box delimits the blood sinus. Outer and inner region of epithelial cells were defined for statistical purposes as described in the method section. c1: general view of the ventral bend, c2: corresponding transmission image. Arrows mark the mucus-filled vacuoles within the SMGs. ROI = region of interest. Scale bar = 20 μm
