HeLa cells stably expressing the BAC-encoded GFP-labeled hPrp8 snRNP and MS2-mRED protein and treated with doxycholine to express the E3 transgene. Shown is the mRED signal. Cells imaged witb a Leica...

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...

Live mitotic HeLa cell treated with epsin1 siRNA, DiOC6(3)to label mitotic membranes (green), and Hoechst 33258 to label chromosomes (blue). Confocal images were taken at 0.118 μm steps along the Z-...

Confocal image of villi from the human small intestine. The finger-like shape increases the surface area of the intestine, improving the efficiency of food absorption. The intestinal crypts (enzyme se...

Human HeLa cancer cells in culture showing the nuclei in red and the tubulin component of the cytoskeleton in green. The blue staining is a mitotic checkpoint protein that remains in the cytoplasm unt...

Confocal micrograph of the brain of a transgenic zebrafish embryo. Some neurons express the green fluorescent protein (GFP) - shown in green under the control of a specific promotor. Tracts, axons and...

Confocal micrograph of the anterior region of the developing zebrafish brain (consisting of the telencephalon, part of diencephalon and the optic tectum). Some of the neurons (shown in green) express ...

Fluorescent micrograph showing human osteosarcoma cells grown in culture. Osteosarcoma is the most common form of bone cancer and occurs due to an error in the growth of osteoblast cells, the cells th...
