Image shows a metaphase spread revealing the 46 human chromosomes (blue). Telomeres have been labeled using PNA-FISH and appear as pale dots at the ends of each chromatid.

Fluorescent micrograph of epithelial cells from the bladder wall. The cells were isolated immediately after collection of a urine specimen and are not fixed. The image was taken using a standard epi...

Fluorescent micrograph of a Tilia tree taken at 10X. Honorable Mention, 2011 Olympus BioScapes Digital Imaging Competition®.

Immunolabeling of endogenous splicing factor SC35 (red) and transfected FP-tagged lamin B receptor. Image stack was acquired using a Deltavision deconvolution microscope.

Human umbilical vein endothelial cells stained initially for nuclei with DAPI (blue) and for vascular endothelial cadherin (red).

A polymorphic immune cell (red) glides over two spherical V12Ras-transformed mucus-secreting cells (green, possible tumor precursors) in a live three day old zebrafish embryo. This is one of four imag...

Fluorescent micrograph of A549 cells (adenocarcinomic human alveolar basal epithelial cells) showing the nucleus (blue) and mRNAs of TFRC (transferrin receptor) identified by fluorescently labeled oli...

Fluorescence micrograph showing the cross-section of bulrush (Juncus sp.) leaf, autofluorescing red (chlorophyll on external side of leaf) and blue (vascular bundles). The diameter of the stalk is ap...

Fluorescence micrograph of a Pine stem. Honorable Mention, 2011 Olympus BioScapes Digital Imaging Competition®.

Patient-derived glioma stem cells treated with a PLK1 (serine/threonine-protein kinase) inhibitor and stained for nuclei (blue), alpha-tubulin (green), phospho-histone H3 (red).
