Zebrafish Notogenesis and Early Neurulation. Mediolateral intercalation produces convergent-extension of the notochordal rudiment. Cells within the center of the notochord elongate and are incorporate...

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...

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...

Scanning electron micrograph of normal red blood cell (background, colored red) and red blood cell affected by sickle-cell anaemia (foreground, colored tan). Sickle-cell anemia is a blood disease that...

Individual Mouse Aortic Endothelial Cell (MAEC) migrating in a 3-dimensional collagen gel (1.4mg/mL). Imaged on a spinning disk confocal microscope using a 100x oil immersion objective lens on a Nikon...

This is a migrating epidermal cell showing vigorous lamellipodial ruffling more than 180 degrees around its circumferance. The cell becomes elongated into a canoe shape. The mechanical tension generat...
