Platinum replica depicting the cytoskeletal organization of dendritic spines in extracted 14 DIV neurons. Mushroom spines associate with dendrites at the base (bottom) and with axons by the head (top)...

Platinum replica depicting the cytoskeletal organization of dendritic spines in extracted 14 DIV neurons. This image shows the interaction of putative PSD from the spine head with axonal intermediate ...

Time lapse movie prepared from spinning disc confocal images of Drosophila S2 cells stably expressing pMT-Eos2-alpha tubulin. A diagonal ~2.5 micrometer strip was photoconverted and images taken every...

An anoptral contrast micrograph of a planktonic freshwater rotifer. The rotifer are microscopic but complex animals (mostly less than 1mm long) found in wet habitats. They are important members of the...

Scanning electron micrograph showing in vitro fertilization of a hamster oocyte. The sperm head, near the center of the field of view, is engulfed by the microvilli on the surface of the oocyte membr...

Scanning electron micrograph showing a lateral view of sperm penetration of a hamster oocyte during vitro fertilization. As the membrane of the sperm head fuses with that of the oocyte, the microvill...

Light micrograph of human ovum (egg) and sperm. The ovum is much larger than the sperm and is surrounded by protective cumulus cells around the outside surface (yellow). The membrane surrounding the o...

Time series spinning disc confocal images of Drosophila S2 cells stably expressing pMT-Eos2-alpha tubulin. A diagonal ~2.5 micrometer strip was photoconverted and images taken every minute for 20 minu...

Platinum replica illustrating the cytoskeletal organization of dendritic spines from extracted 14 DIV neurons. Thin spines associate with dendrites at the base (bottom) and with axons by the head (top...

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...
