HeLa cell in cytokinesis was fixed and stained for microtubules (green), RacGAP1 (red), and DNA (blue). Cells were fixed with MeOH on ice for 3 min, and stained with a primary antibody against RacGA...

Visualization of yolk syncytial layer (YSL) nuclei in living zebrafish embryos. Sytox Green, a membrane-impermiant vital nuclear stain, was injected into the yold cell of late blastula (sphere stage)...

Confocal microscope image of a portion of a human 5-day embryo illustrating the trophoblastic shell. Interphase microtubules (green) are labeled with alpha/beta tubulin primary antibodies. FITC conjug...

Frog (Xenopus laevis) egg arrested in metaphase of mitosis. Note the tiny metaphase spindle on the top left of the egg. Eggs were fixed in 90% MeOH; 10% (H20 500mM EGTA) and stained for DNA with YoP...

Dynamics of Cellular and Syncytial Endoderm. An ectopic embryonic axis was induced by injecting a marginal blastomere of a 32-cell stage embryo with TARAM-A (Tar*, a receptor for Nodal-like ligands) R...

Confocal micrograph showing the tissue structures within the leaf of an Arabidopsis thaliana seedling. The sample was fixed and stained with propidium iodide, which labels DNA, and imaged four years l...
