Representative microscopic images of each subgroup prepared by #25/.02 and #25/.06 after incubation for 6 h with CNI and PIPS in the coronal region (a), middle region (b) and apical region (c). The value of average fluorescence density in the coronal (d), middle (e) and apical (f) regions. ATP levels are shown in g. *p < 0.05, **p < 0.01, ***p < 0.001. Scar bar = 400 μm
