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...

Transverse section through the neural tube of an early stage chick embryo. The brown stain shows the neurofilament in the axons of the commisural neurons (running down the sides of the neural tube) an...

Fluorescence image of bodies and axons of the mesencephalic trigeminal nucleus in a 4 day old chick embryo. The trigeminal nucleus is made up of scattered neurons along the midline of the optic tectum...

Zebrafish embryo showing the alignment of cells involved in the formation of the neural tube, which will become the spinal cord and brain.

Neural plate of Xenopus laevis at early neural tube closure.

Differentiated rat neural stem cells stained for β III-Tubulin (in blue) to reveal neurons and GFAP (in red) to reveal glial cells.

Zebrafish at the 3-somite stage. A dorsal view of the embryo, focused first at the level of the hypoblast. The notochord is centrally located. The first three frames of the sequence are at the same ti...

Zebrafish Embryo, from tailbud to 16-hour stage, stained with 100 micromolar Bodipy-Ceramide. Bodipy-Ceramide permeates the enveloping layer epithelium of the embryo, accumulating in the interstitial ...

Differentiated rat neural stem cells stained for β III-Tubulin (in green) to reveal neurons, GFAP (in red) to reveal glial cells, and DAPI (in blue) to label nuclei.
