Gap junctions in papillary muscle from cat heart. These communicating junctions are responsible for the spreading wave of depolarization through the myocardium. Desmosomes can also be found on the l...

This electron micrograph is a cross section through a portion of an axon and its associated myelin wrap from the cochlear nerve of the cat. This high magnification view showcases the regular periodic...

Representative examples of gap junctions from vertebrates (ciliary epithelium from the eye of a Macaca mulatta, upper) and invertebrates (inverted gap junctions from cells of the mid-gut of the horses...

Typical organization of gap junctions as seen in thin sections (upper) and replicas of freeze-fractured cell membranes (middle and lower). Upper, gap junction from the saccular macula of a goldfish; ...

Freeze fracture images of synaptic junctions in the retina of Macaca mulatta. The electron micrograph in the top panel shows two invaginating synapses between cone and horizontal cells in the outer p...

Wild-type Arf1-GFP (Arf1(WT)-GFP) (gray) does not block redistribution of Helix Pomatia Lectin (HPL) (green) from Golgi to ER in Src-deficient SYF fibroblasts cotransfected with active Src (SrcE-DsRe...

A colorized scanning electron microscope picture of a nerve ending that has been broken open to reveal the synaptic vesicles (orange and blue) beneath the cell membrane.

Colorized image of Bidens Ferulifolia pollen on plant structures collected with a dual beam SEM/FIB microscope.

Boi (green) and Hedgehog (Hh, red) are expressed in apical cells of the Drosophila wild-type germarium (CIL# 13744). In the absence of boi (boi[e] mutant), Hh is redistributed from apical cells to the...
