Scanning electron micrograph of single guinea pic pancreatic acinar cells attached to a duct. Image made available by James D. Jamieson and the Department of Cell Biology, Yale University School of ...

Transmission electron micrograph illustrating the 'classic' appearance of the nucleus in osmium tetroxide fixed material. In this pancreatic acinar cell nucleus, the only prominent feature is the lar...

Transmission electron micrograph of glutaraldehyde fixed pancreatic acinar cell showing the characteristic features of nuclear chromatin with this preparative method. Darkly staining heterochromatin (...

Nomaski image of live guinea pig pancreatic acinar cells. Image corresponds to Figure 1 in Proc Natl Acad Sci U S A. 1972 Oct;69(10):3028-32. Image made available by James D. Jamieson and the Departm...

Scanning electron micrograph of single guinea pig pancreatic acinar cell. Image made available by James D. Jamieson and the Department of Cell Biology, Yale University School of Medicine.

Transmission electron micrograph of a pancreatic acinar cell from the bat Myotis lucifugus showing the 'classic' ultrastructural features of the nucleus after glutaraldehyde fixation. The large darkly...

Transmission electron micrograph of exocytosis taken from the rat pancreas. Images such as these indicated that secretory granules closely and selectively approach the apical membrane of the pancreat...

Stacks of rough endoplasmic reticulum (ER) cisternae seen in a transmission electron micrograph of a section through a secretory acinar cell from the bat exocrine pancreas. The rough ER is here involv...

Transmission electron micrograph of nucleus showing the characteristic features of glutaraldehyde fixation introduced as a primary fixative in 1962 and since used routinely. Chromatin appears differen...
