Confocal micrograph of teased sciatic nerve fibers. The fibers are triple labelled for neurofilament (blue), S100 (red) and dystrophin-related protein (DRP2) (green). The S100 protein is expressed in...

Confocal microscope image of a 3T3 fibroblast cell. The nucleus has been stained blue, and two components of the cytoskeleton, actin microfilaments and intermediate filaments, are stained red and gree...

Fluorescent micrograph showing a section of human appendix infected with the measles virus. The measles virus is shown in green, cytokeratin is shown in red, which marks the epithelium, and Dapi stain...

Fluorescent micrograph of differentiating mouse embryonic stem (ES) cells. Embryonic stem cells are pluripotent, meaning that they have the ability to differentiate into any cell type depending on th...

This confocal image shows a 13.5 days post coitum female mouse gonad at high magnification (x40). The developing ovary and mesonephros were fluoresently stained with an endothelial and germ cell marke...

Confocal micrograph of the posterior portion of the digestive tract of an adult Drosophila fly. The circular visceral muscles are labelled in red with phalloidin staining of actin. The main nerves are...

Confocal micrograph showing the innervation of the posterior portion of the digestive tract of an adult Drosophila fly. The circular visceral muscles are labelled in red with phalloidin staining of ac...

Cryopreserved human mammary epithelial cells were revived and stained for cytokeratin 18 (in red) to reveal the keratin-containing intermediate filaments found in the intracytoplasmic cytoskeleton of ...

Differentiated rat neural stem cells stained for β III-Tubulin (in blue) to reveal neurons and GFAP (in red) to reveal glial cells.

Differentiated rat neural stem cells stained for β III-Tubulin (in green) to reveal neurons, GFAP (in red) to reveal glial cells, and DAPI (in blue) to label nuclei.
