Fluorescent micrograph of a Drosophila melanogaster reproductive system highlighting the muscular and neural structure fruitfly ovaries and uterus. The background staining of the eggs in red is a spe...

Time lapse movie of a developing sand dollar embryo expressing GFP-histone H2B. The movie shows several rounds of mitoses.

Sand dollar embryos expressing GFP-H2B going thru stages of mitosis. Video is animated with the cursor indicating the stages of mitosis and the morphological characteristics of the stage during the t...

Yolk syncytial layer nuclei undergo epiboly and converge dorsally during late gastrulation. Video made available by Mark Cooper through Zebrafish - The Living Laboratory.

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

The image shows a developing Drosophila spermatid immunostained for caspase activity (green). TRITC-phalloidin is used to label actin (red). Caspase is required in spermiogenesis for the elimination ...

Fluorescent micrograph of stage V-VI Xenopus laevis oocytes surrounded by thousands of follicle cells, as visualized by Hoechst staining.

Cryopreserved human hair follicle dermal papilla cells were revived and stained for vimentin (in green) to reveal cytoskeleton, and DAPI (in blue) to label nuclei.
