Timelapse of dorsal yolk syncytial layer (YSL) nuclear movements during zebrafish gastrulation. A marginal band of YSL nuclei undergo epiboly toward the vegetal pole while internal-YSL (I-YSL) nuclei ...

This electron micrograph shows a cross section through the midpiece of opossum sperm. Filamentous cytoplasm underlies a scalloped membrane with regular variations in thickness, which gives it a corrug...

Confocal micrograph showing Shigella bacteria (pink) invading the intestinal lining. The bacteria infects the cells by high-jacking the cell's internal actin skeleton (green) to facilitate its entry i...

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. ...

Video of goldfish (CAR) fish fibroblast taken with a confocal microscope showing the dynamics of the focal adhesion protein paxillin (red), microtubules and the tip protein EB3 (green), and actin (blu...

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...

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...

Individual deep cell moving by circus movements. Fundulus heteroclitus(killifish) embryo. Images made available through Mark Cooper and Zebrafish The Living Laboratory.

Individual deep cells migrating by blebbing and lamellipodial activity in a fundulus heteroclitus (killifish) embryo. Video made available thru MarK Cooper and Zebrafish The Living Laboratory.

The flagellar pocket of a Trypanosoma brucei bloodstream form cell, with short flagellum. The image shows a new flagellum starting to grow from the flagellar pocket, in preparation for the next cell d...
