NCC is up-regulated in gills under acid stress. (A, B): Immunostaining images of NCC (arrow) in gills filaments under pH7 or pH4 FW for 7d. (C, D): Comparisons of NCC cell density in gill filaments ( C ) and of NCC cell number in both gill lamella and filament ( D ) between pH7 (white bars) and pH4 FW (gray bars) for 7d. Means ± SD (n = 8). *p < 0.05 (Student’s t-test). Scale bar = 100 μm.
