High magnification scanning EM of the extracellular matrix of the notochord sheath. Specimens were chemically fixed critically point dried, and sputter coated with gold/palladium. This image is par...

Confocal micrograph of a transgenic zebrafish embryo at 24 hours post-fertilization, showing expression of the fusion protein PARD3_GFP. PARD proteins, which were first identified in C. elegans, are e...

Fluorescent micrograph showing transgenic zebrafish embryos expressing green fluorescent protein in the muscle precursor cells (myotomes). The green fluorescence comes from an alpha-actin-GFP transgen...

Timelapse of dorsal side during gastrulation shows migration of hypoblast and underlying yolk syncytial layer (YSL) nuclei (larger bright spots). The prechordal plate can be seen as a more clumped mas...

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 ...

Timelapse of dorsal yolk syncytial layer (YSL) nuclei and blastoderm morphogenesis from sphere stage (late blastula) to 1 somite stage. Top panel shows Nomarski movie of blastoderm morphogenesis inclu...

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...

This is a movie that depicts somite formation in a live knypek; trilobite double mutant embryo. This is a dorsal view with anterior towards the top and time points were 15 minutes apart. Somites in kn...

Zebrafish midbrain hindbrain morphogenesis as seen with bodipy-ceramide and fluorescent dextran labeling. Video made available by Mark Cooper through Zebrafish - The Living Laboratory.

Confocal z-stack of a dividing zebrafish embryo. The fixed embryo is visualized using EMTB-3GFP (microtubules-marker - green), phalloidin (actin marker -red) and Hoechst (DNA marker - blue).
