Montage image of a brain stem from a Brainbow transgenic mouse. In Brainbow mice, neurons randomly choose combinations of red, yellow and cyan fluorescent proteins, so that they each glow a particular...

Confocal image of pastel neurons in the hippocampus of a "Brainbow" mouse brain, with each neuron expressing a distinct color. In Brainbow mice, neurons randomly choose combinations of red, yellow a...

Light micrograph of elastic cartilage of the ear. This type of cartilage is made from a protein called elastin and is formed from a network of elastic fibers and collagen. The fibers form bundles whic...

Light micrograph of elastic cartilage of the ear. This is a type of cartilage (connective tissue) that is present in the outer ear. It contains a network of collagen and elastin fibers, which gives it...

Living Lilium pollen tube labeled with mitotracker green to mark mitochondria (green) and cytochalasin D TRITC to mark endoplasmic reticulum (red) imaged using laser scanning focal microscopy. Shown i...

Living Lilium pollen tube labeled with mGFP5-HDEL to mark endoplasmic reticulum (green) imaged using laser scanning focal microscopy. Shown is a central 1.0 micron thick x-y slice. The growing tip is...

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 ...

Freeze substituted Lilium pollen tube immunolabeled for filamentous actin and imaged using laser scanning confocal microscopy. Shown is a projection of z-slices revealing the dense sub-apical actin fr...
