Drosophila melanogaster Kc167 cells were stained for DNA (to label nuclei, red) and actin (a cytoskeletal protein, to show the cell body, green). Each image is a dual channel fluorescent image followe...

Liver of a rat exposed to chemical carcinogens. Serial sections of the liver imaged by laser scanning confocal microscopy. F-actin (red) is in bile canaliculi at junctions of the hepatocytes, which ...

Junctional complex between two cells in the epithelium of the rat intestinal mucosa. The tight junction (also known as zonula occludens) is the structure located nearest to the lumen. The elimination ...

Junctional complex between two cells in the epithelium of the rat intestinal mucosa. The tight junction (also known as zonula occludens, ZO) located nearest to the lumen extends from arrow 1 to arrow ...

A single slice through the middle of a tomographic reconstruction of Purkinje cell spines from rat cerebellum, labeled for F-actin by photoconvertable phalloidin. For more information, see: Capani F;...
