Ultrastructural study on the centro-acinar cells of the mink pancreas with particular reference to the acetyl cholinesterase (AChE) activity.
The centro-acinar cell (CAC) of the pancreas of 8 mink specimens were studied under ultrastructural points of view with regard to the distribution of acetyl cholinesterase. The subcellular characteristics observed do not suggest an important participation in the production of transport secretory proteins, but do indicate some function in electrolyte transport. The reaction for specific cholinesterase was postive, particularly close to the basal and lateral plasmalemma of the CAC, in the intercellular spaces between these cells, and next to nerve endings. Some of these endings present small agranular vesicles, and other, besides these vesicles, show large cored ones. Nerve endings and CAC are very close together, although being separated by their basal membranes.
