title: Ultrastructural evidence for a possible secretory function of Merkel cells in the barbels of a teleost fish, Cyprinus carpio.
abstract: Examination of barbels of the carp (Cyprinus carpio) revealed cells showing the characteristics of Merkel cells. Some ultrastructural features of these cells suggest a secretory function.
