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.

Nuclear pores are clearly seen in these transmission electron micrographs of cells after cryo-fixation, freeze-fracture and surface replication. Upper panel shows the outer surface of of the nuclear e...

Transmission electron micrograph of the salivary gland of the tick Rhipicelphals appendiculatus illustrating the dramatic difference in nuclear size seen in different cell types. Here, the large (prob...

Tubules within the cristae of mitochondria can sometimes take on unusual configurations. Here, in the upper panel, a mitochondrion from an astrocyte in hamster brain appears to have prismatic tubules...

Transmission electron micrographs showing the unusual nucleolar structures in Sertoli cells of ruminants, with varying numbers of vesicles and tubules; the upper panel illustrates such an organization...

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...

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...

Figure 374 from Chapter 15 (Cytoplasmic Inclusions) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Cell type-f from Acinus III in the salivary gland of the tick Rhipicephalus appendiculatus. These ce...

Immunoelectron microscopy of mammary gland tissue from lactating rats with medial cisternae of the Golgi apparatus indicated by immunogold labeling of MG-160, a 160 kDa membrane sialoglycoprotein spec...
