Summary
Close contacts between exocrine and endocrine cells were observed in human and rat pancreas. The presence of junctional specializations, including desmosomes, tight and gap junctions, as well as interdigitations between endocrine and exocrine cells, implies that these cells are structurally and functionally associated.
