  • Title: The occurrence of argyrophilic and argentaffin cells in the gut of Ciona intestinalis L.
    Author: Fritsch HA.
    Journal: Cell Tissue Res; 1976 Nov 24; 175(1):131-5. PubMed ID: 1000594.
    Abstract:
    Argyrophilic and argentaffin cells occur in the stomach and intestinal epithelium of the sea-squirt, Ciona intestinalis L. These cells are characterized by their basal swelling which contains the nucleus surrounded by small secretory granules and by a filamentous cell-apex which reaches the gut lumen. The cells are scattered unevenly within the epithelium. Their number decreases rapidly towards the lower part of the intestine. The localization, size of granules and their shape are features which differentiate these cells from other secretory cells in the gut epithelium such as mucous cells. These cells are thought to possess an endocrine function.
