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...

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...

Gallbladder wall of a human patient with gallstones. The top layer is composed of highly polarized epithelial cells with microvilli partially visible at the apex and dark nuclei at the base. Below ...

Gallbladder wall of a human patient with gallstones. This low magnification view shows the wall of the diseased gallbladder to have a top layer of highly polarized epithelial cells over a large volu...

This confocal micrograph shows a dorsal root ganglion (DRG) explant. The dorsal root ganglion is a swelling on the dorsal roots of spinal nerves, which contains a cluster of cell bodies and synapses. ...

Timelapse of yolk syncytial layer (YSL) nuclear movements during gastrulation from a dorsal-anterior view shows epiboly, early animal pole directed movements of I-YSL nuclei, and convergence and exten...

A high resolution image of an individual cirrus of Euplotes with 91 cilia/basal body complexes. The transition from basal body to cilium can be followed from right to left in each row. Small vesicles,...

A high resolution image of the transition from basal bodies to cilia within a portion of one of the oral membranelles of Euplotes. Parasomal sacs occur between the rows of basal bodies although these ...

Individual deep cell moving by circus movements. Fundulus heteroclitus(killifish) embryo injected with GFP-actin plasmid at 1-cell stage, filmed during gastrulation. Image made available through Zebra...
