Scanning EM of the somites (myotomes), of a 24 hr (prim-5) zebrafish embryo. Specimens were chemically fixed critically point dried, and sputter coated with gold/palladium. This image is part of a s...

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...

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...
