Rolling of leukocytes on the walls of the caudal vein in a larval zebrafish; real time. As in adult mammals, such rolling occurs only in veins, not in arteries. Video made available by Mark Cooper th...

A polymorphic immune cell (red) glides over two spherical V12Ras-transformed mucus-secreting cells (green, possible tumor precursors) in a live three day old zebrafish embryo. This is one of four imag...

4D data set of yolk syncytial layer nuclear movements. Movie shows z-series stacks sequentially through time. Numbers label individual nuclei so they can be tracked in 3D space at each time point. Vi...

Confocal projection of Zebrafish yolk cells expressing H2B-cherry (red) to mark the nucleus and a GFP membrane marker (green) to show the outline of the cells.

Zebrafish development from cleavage until tailbud formation. This video made available through Mark Cooper and Zebrafish - The Living Laboratory.

3 hr zebrafish embryo labeled with anti-phosphotyrosine antibody (green) and anti-phosphoserine (red). Images made available by Mark Cooper thru The Zebrafish A Living Laboratory.

Rhodamine-phalloidin (actin stain) in the trunk of a 24 hr zebrafish embryo. Images made available by Mark Cooper thru The Zebrafish A Living Laboratory.

Zebrafish development from extension of head and tail rudiment during axiation, somitogenesis. Video made avaialable through Mark Cooper and Zebrafish - The Living Laboratory.

Confocal micrograph of the brain of a transgenic zebrafish embryo. Some neurons express the green fluorescent protein (GFP) - shown in green under the control of a specific promotor. Tracts, axons and...
