Fluorescent micrograph of a Xenopus melanophore, showing microtubules (green), microtubule plus ends (red) and nucleus (blue). Honorable Mention, 2011 Olympus BioScapes Digital Imaging Competition®...

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...

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...

These examples of ependymal epithelium from the rat brain represent epithelia that lack zonulae occludentes. Further, there appears to be no consistent order to the junctional specializations that are...
