Although the first observations on the existence of more than one cell type in the islets of
Langcrhans date back about 40 years (Laguesse, 1894 and'05); Diamare, 1899; …

A4s is well known, the pancreas of vertebrate animals is studded with groups of peculiar
cells which are characterized by a transparent appearance due to the lack of zymogen …

During the past thirty-five years the knowledge of the finer details of the structure of the islets
of Langerhans has been increasing steadily. Laguesse ('95,'06) found that the islet cells …

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 …

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 …

Several investigators, while studying the development of the pancreatic islet, have
distinguished between primary and secondary islets (Laguesse,'06; Van Campenhout,'25; …

The object of this investigation was to establish an electron microscopic identification of the
different types of cells present in the islets of Langerhans. This identification of the islet cells …

In the course of a comparative study of the pancreas, begun in the autumn of 1905, I was
struck with a peculiar reaction in certain cells of the Islets of Langerhans in the pancreas of …

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 islet tissue was first described by Paul Langerhans in 18691 while he was
still a medical student. Langerhans identified a new cell type in the pancreas which had not …
