Scanning EM of a 24 hr (prim-5) Zebrafish embryo, fractured to reveal the neural tube, migrating neural crest cells, the notochord and the somites. Specimens were chemically fixed critically point ...

Scanning EM of a 24 hr (prim-5) Zebrafish embryo, showing the fibrous extracellular matrix connecting the mesoderm to the migrating neural crest cell. Specimens were chemically fixed critically poi...

Figure 370 from Chapter 15 (Cytoplasmic Inclusions) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Ectoderm cell from a blastula of Rana pipiens. This cell shows a number of yolk platelets, lipid dro...

Dorsal root ganglion nerve cells stained to reveal the microtubules (green) and actin filaments (red). The axon shaft contains bundles of microtubules that give structural support and carry cargo (pro...

Fluorescent micrograph of rat embryo fibroblast cell growing in serum stained to reveal actin stress fibres (red) and vinculin (component of focal adhesions) in green/yellow.

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) 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...

High magnification scanning EM of the extracellular matrix in the ventrolateral mesoderm of a 24 hr (prim-5) Zebrafish embryo. Specimens were chemically fixed critically point dried, and sputter coate...

Scanning electron microscope image of Strongylocentrotus drobachiensus [sea urchin] at the gastrula stage. Embryo was cut in half to reveal blastocoel cavity, containing blastocoel matrix material, pr...
