Intestinal epithelium from the adult midgut of Drosophila melanogaster were immuno-stained for the cell periphery (integrin, red), nuclei (DAPI, blue) and stem cells (green). Nuclei are not seen in th...

This electron micrograph shows the plasma membrane of epithelial cells of the brush border of the cat intestine, obtained from a thin section parallel to the free surface. The ability to visualize ce...

This pair of confocal micrographs demonstrates how a disease-causing strain of E. coli bacteria brings about diarrhoea by breaking down the waterproof barriers between the cells. The bacteria are seen...

Early transmission electron micrograph of guinea pig pancreas showing ribosome-studded rough endoplasmic reticulum with secretory granules accumulating in the lumen (cisternae). Image made available ...

Mouse tracheal epithelia cells (MTEC) were grown at air-liquid interface to induce differentiation, centriole amplification and ciliogenesis. Cells were fixed using ice-cold methanol for 10 min. Sampl...

Figure 389 from Chapter 15 (Cytoplasmic Inclusions) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Secretory granules in an alpha cell of an islet of Langerhands in human pancreas. In this EM preparati...

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...
