Chloride Transport Across Isolated Opercular Epithelium of Killifish: A Membrane Rich in Chloride Cells

The opercular epithelium of Fundulus heteroclitus contains typical gill chloride-secreting cells at the high density of 4 × 10$^{5}$ cells per square centimeter. When isolated, mounted as a membrane, and short-circuited, it actively transports chloride ions from the blood side to the seawater side o...

Zusammenfassung:	The opercular epithelium of Fundulus heteroclitus contains typical gill chloride-secreting cells at the high density of 4 × 10$^{5}$ cells per square centimeter. When isolated, mounted as a membrane, and short-circuited, it actively transports chloride ions from the blood side to the seawater side of the preparation. This preparation offers a useful approach to the study of osmoregulation in bony fishes.
