Kidney histology in wild-type and ctns−/− zebrafish. (A,B) Representative images of renal tubules of wild-type (A) and ctns−/− (B) 18-month-old zebrafish. Details of proximal tubules with hyaline-like eosinophilic droplets (black arrowheads) and cytoplasmic vacuoles (*). H&E staining. The scale bars represent 50 µm. (C,D) Representative images of the PAS staining of renal tubules of wild-type (C) and ctns−/− (D) 18-month-old zebrafish. Details of proximal tubules with hyaline-like droplets (black arrowheads) and cytoplasmic vacuoles (*). PAS staining. The scale bars represent 50 µm. PT: proximal tubule; DT: distal tubule.
