Summary
Ciliated cells occasionally occur in pancreatic ductule cells and islet β-cells of normal Chinese hamsters. In the regenerating pancreatic parenchyma of alloxan-treated Chinese hamsters an increased amount of cilia is observed in the ductule cells and islet β-cells. No obvious cilia were found in the other pancreatic cell types of normal and alloxan-treated animals. One and the same ductule cell possesses one, two, or rather often many cilia protruding into the ductule lumen. In the islet β-cells there are one or two cilia that often extend into intercellular spaces. The fibre arrangement varies in different parts of the cilia. The basic fibre pattern seems to be 9 + 2, the 9 peripheral fibres consisting of 2 subfibres, and the 2 central being single. The basal bodies (centrioles) consist of 9 groups of 2 or 3 aligned tubular elements. Filaments are associated with the centrioles. The functional significance of the cilia is discussed.
