This confocal micrograph shows a dorsal root ganglion (DRG) explant. The dorsal root ganglion is a swelling on the dorsal roots of spinal nerves, which contains a cluster of cell bodies and synapses. ...

Light micrograph of onion (Allium cepa) root tip cells stained with acetocarmine to show nuclei and chromosomes. The field includes cells in interphase, prophase, metaphase, and late telophase.

A video of Arabidopsis thaliana showing a lateral root growing out of the primary root. Arabidopsis thaliana is widely used as a model organism in plant biology. This movie is created from image sta...

This is a region of a (semithin) longitudinal section of onion root taken from the meristematic zone; this is the undifferentiated region of plant tissue from which new cells are formed. Therefore, it...

At the root tips of the mustard plant Arabidopsis thaliana (cell walls shown in red), two proteins work together to control the uptake of water and nutrients. When the cell division-promoting protein ...

Experiment 1

Dorsal root ganglion cells from embryonic mice were cultured and stimulated to produce cyclooxygenase-2 (COX-2). Cultures were immuno-stained for neuron-associated tubulin (green), COX-2 (red) and DNA...

Experiment 1

The image shows a nucleus isolated from Arabidopsis thaliana immunostained for the HDA6 histone deacetylase (red). DNA is stained blue. HDA6 concentrates in the nucleolus (top center), where ribosom...
