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 …

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 …

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 …

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; …

MATERIALS AND METHODS In this survey the paiicreases of forty-one different species of
mammals, representing ten orders and twenty-five families, have been studied. Whenever …

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

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

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 …

The distribution of alpha, beta, and other islet cells in the tail of the pancreas of the Central
American monkey (Saimiri sciurea) revealed by the light and electron microscopes, is similar …
