Ultrastructure of marine teleost gill epithelia: SEM and TEM study of the chloride cell apical membrane

Abstract

This paper deals with the structure of gill epithelia in the sole, Solea solea, as revealed by transmission and scanning electron microscopy. In this marine teleost the chloride cell and its accessory cell form a cellular complex. Apically the plasma membranes of these cells are loosely juxtaposed, thus forming a leaky epithelium covering a large part of the gill.
