[The morphologic basis for asynchronous secretion by pancreatic cells].
Electron microscopic study of the pancreas of the vertebrates showed that asynchronous secretion of the pancreatic cells was regulated by means of the cytoplasmic extrusion. The latter provided selective entrance of the initial substances from the pericapillary spaces into the cells. Cytoplasmic extrusion also regulated the passage of the hormonal and other metabolites from the intercellular spaces into the pericapillary space.
