Zebrafish embryo at tailbud stage The sequence begins at the level of the axial hypoblast. The hypoblast has separated into paraxial and axial mesoderm. The axial mesoderm (chorda mesoderm) is the pre...

Morphogenesis of the ventral yolk syncytial layer (YSL) from sphere stage to the end of gastrulation. The last round of nuclear division occurs before marginal band contraction and epiboly begins. As ...

NIH 3T3 cell (mouse embryonic fibroblast line) stained for Actin (green) and DNA (blue). PLoS Biology February 2009|Volume 7|Issue 2| e1000038 Active-Site Inhibitors of mTOR Target Rapamycin-Resist...

Gallbladder wall of a human patient with gallstones. The duct (clear zone at center) is lined by highly polarized epithelial cells with dark nuclei at the base. At the top of the picture, below the...

This fluorescent micrograph shows a microelectrode penetrating the cell body of a neurone in the retina of a living eye. The electrode is injecting a fluorescent dye (lucifer yellow) into the cell, fi...

Confocal microscope image of a developing Purkinje cell in the cerebellum of a 9 day postnatal rat. The cerebellum contains millions of these cells which are involved with integrating motor and sensor...

Confocal micrograph of NIH-3T3 cells co-transduced with 5 fluorescent proteins. The cells were marked by co-transduction with Lentiviral Gene Ontology (LeGO) vectors expressing Cerulean (cyan), EGFP ...

Epiboly movements of yolk syncytial layer (YSL) nuclei during gastrulation from a dorsal-vegetal pole view. A marginal band of nuclei moves toward the vegetal pole during epiboly, while some nuclei mo...

Dorsal cell movements during zebrafish gastrulation includes a combination of epiboly, involution, and convergence and extension along the embryonic axis. Note that videos CIL 11818, 11819, and 11820...

Zebrafish embryo at the 5-somite stage The cross-sectional view is in the ventral portion of the neural keel. In the lower portion of the image, somites detach from ventral mesoderm. Oriented division...
