Ultrastructural and ultracytochemical studies of the gill epithelium in the larvae of Salamandra salamandra (Amphibia, Urodela) (original) (raw)

Summary

The morphology of Salamandra salamandra (Linné, 1758) larva gills is described by scanning and transmission electron microscopy. Three main cell types comprising the surface of the gill epithelium are described: (a) pavement cell, (b) ciliary cell and (c) mitochondria-rich cell (MRC). Two subtypes of MRC were distinguished by their ultrastructural characteristics: a fibrillar cell and a tubulovesicular cell. Kü-dependent-nitrophenyl-phosphatase (K-NPPase) activity, indicative of Naü-Kü-ATPase activity was confined to the basolateral membranes of the pavement cells. MRC were devoid of such activity. Possible relationships between structure and function of the different cell types are discussed.
