Spartium flower primordium (bud), captured using epi-illumination. Honorable Mention, 2010 Olympus BioScapes Digital Imaging Competition®.

Yolk syncytial layer nuclei undergo epiboly and converge dorsally during late gastrulation. Video made available by Mark Cooper through Zebrafish - The Living Laboratory.

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...

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.

This image shows human cardiac microvascular endothelial cells forming tubes in Matrigel. Matrigel is a gelatinous protein mixture that encourages cells to demonstrate complex cellular behavior that i...

A 4D visualization of zebrafish somitogenesis and neural keel formation. The Quicktime movie shows progressively dorsal optical sections in a segmenting embryo. Note the midline alignment of neuroepit...

Yolk syncytial layer cell nuclei exhibit convergence and extension behaviors during late gastrulation. Video made available by Mark Cooper through Zebrafish - The Living Laboratory.

Eye of a 24 hr zebrafish embryo stained for paxillin (green) and laminin (red). Images made available by Mark Cooper thru The Zebrafish A 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.

Timelapse of dorsal yolk syncytial layer (YSL) nuclear movements during zebrafish gastrulation. A marginal band of YSL nuclei undergo epiboly toward the vegetal pole while internal-YSL (I-YSL) nuclei ...
