Pancreatic islets have been studied by the electron microscopy of ultrathin sections in
mature guinea pigs and cats. Alpha cells contain specific granules which are notably dense …

A comparative study of the pancreatic islets of Langerhans was undertaken in which
correlative thick-thin sectioning techniques for light and electron microscopy were used. This …

The pancreatic islets of the guinea pig have been studied by light and electron microscopy.
The B granules in glutaraldehyde-fixed tissue often are cup-shaped with an indentation …

Light-and electron-microscopic observations were made on the alpha, beta and delta cells
of the pancreatic islets of the domestic fowl and on their cytologic changes following the …

The pancreatic islets of rabbit, dog and opossum have been studied by light and electron
microscopy. Silver-positive cells in the rabbit are predominantly sandwiched between the …

The pancreatic islets of the dog, guinea pig and pigeon were studied under the electron
microscope and the following results were obtained. 1. Besides A and B cells, D cells are …

The early development of the pancreatic islet organ is intimately associated with the
development of the whole pancreas. The pancreatic primordia first appear as duodenal …

The pancreatic islet in the mouse has a highly complex and heterogeneous structure. It
contains Aa, Ab, Ac, B, C, D, E, and F cells. The classification of cell types is primarily based …

The electron microscopic study of rabbit pancreatic islets reveals in adthtiun to alpha anti
beta cells a third cell type containing specific secretory graaules. This third cell is considered …

Electron microscopic criteria have been established for the identification of all the different
types of islet cells. A remarkable difference in the ultrastructure of beta granules has been …
