Living Lilium pollen tube labeled with paclitaxel (blue) to mark microtubules (blue) and cytochalasin D TMR to mark endoplasmic reticulum (green) imaged using laser scanning focal microscopy. The grow...

Living Lilium pollen tube labeled with TMRE (red)to mark mitochondria and imaged using laser scanning focal microscopy. Shown is a central 1.0 micron thick x-y slice. The growing tip is devoid of mit...

Living Lilium pollen tube labeled with carboxy-dichlorofluorofluorescein (green) to mark the vacuole and cytochalasin D TMR to mark endoplasmic reticulum (red) imaged using laser scanning focal micros...

Fixed Lilium pollen tubes were treated with fluorescent phalloidin to label filamentous actin, and confocal images obtained. A strongly labeled actin fringe near the growing tip is present. Other i...

Living Lilium pollen tube imaged with DIC optics. Shown is the growing tip with the apical region devoid of cytoplasmic organelles. Other images in the group reveal the distributions of cytoskeletal ...

Differentiated rat neural stem cells stained for β III-Tubulin (in blue) to reveal neurons and GFAP (in red) to reveal glial cells.

Zebrafish at the 3-somite stage. A dorsal view of the embryo, focused first at the level of the hypoblast. The notochord is centrally located. The first three frames of the sequence are at the same ti...

Confocal image of a sea squirt heart. The sea squirt heart is a tube made of a single layer of muscle cells. The contractile elements are the long striations stained red and the nuclei are also red....
