In addition to plates the plasma membrane contains IMPs on its P-fracture face in ring or parenthesis shape at sites of trichocyst secretion. A ring actually consists of two circles of IMPs and signif...

Colorized scanning electron micrograph of a lavender leaf. Lavender (Lavandula) yields an essential oil with sweet overtones, and can be used in balms, salves, perfumes, cosmetics, and topical applica...

Early transmission electron micrograph of secretory cell from the guinea pig pancreas. Secretory granules are prominent in the lumen of the rough endoplasmic reticulum. Image made available by James ...

Electron microscope autoradiograph showing radiographic leucine over elements of the rough endoplasmic reticulum. A few grains are also found over small, smooth surfaced vesicles of the Golgi complex...

Proximity of excitatory and inhibitory axon terminals adjacent to pyramidal cell bodies provides a putative basis for nonsynaptic interactions. Video sequence made up of 14 consecutive confocal micros...

Electron microscope autoradiograph showing radioactivity associated with zymogen granules in the guinea pig pancreas 4 hrs after injection. Image corresponds to Figure 9 in J Cell Biol. 1964 Mar;20:4...

Confocal micrograph of a mast cell in human eye with conjunctivitis. This image shows a single mast cell invading conjunctival tissue in response to an inflammatory agent or pathogen. The mast cell c...

Confocal micrograph showing the hormone-producing enteroendocrine cells of the Drosophila melanogaster adult midgut. The enteroendocrine cell nuclei are labelled with an anti-Prospero antibody (red), ...

Electron microscope autoradiograph showing the high concentration of radioactivity over the condensing vacuoles of the Golgi complex twenty minutes after injection. Image corresponds to Figure 7 in ...

Electron microscope autoradiograph taken 20 min after injection showing that the radiographic label has migrated from the rough endoplasmic reticulum to the Golgi complex. Most of the radioactive gra...
