Image shows a z-series of a mouse ES cell carrying an alpha-globin BAC transgene array (clone 1c) hybridized with probes against the lac operator repeat (green) and the entire alpha-globin BAC sequenc...

Scanning electron microscope image of Strongylocentrotus drobachiensus embryo at the primary mesenchyme blastula stage. Embryo was split open to reveal the outer epithelial layer and the blastocoel ca...

Anterior and posterior regions of a C. elegans embryo are determined by PAR protein distribution. PAR-2, shown in green marks the posterior region of the embryo and PAR-6, shown in red, marks the ante...

Zebrafish Embryo, from tailbud to 16-hour stage, stained with 100 micromolar Bodipy-Ceramide. Bodipy-Ceramide permeates the enveloping layer epithelium of the embryo, accumulating in the interstitial ...

Scanning electron micrograph of a 6 day old human embryo beginning to implant into the lining of the uterus (endometrium). As implantation progresses, the inner cell mass begins to form into the bila...

Stereo pair of an embedment-free section of a detergent-extracted 8-cell embryo reveals the cytoskeletal interior in greater detail than is afforded in resin-embedded sections. The specimen is viewed...

This movie illustrates the early division up to the four-cell stage of a C. elegans embryo expressing YFP::CDC-48 by DIC and fluorescence microscopy. YFP::CDC-48, like YFP::UFD-1 and YFP::NPL-4, are c...

A confocal Z-stack from a transgenic Drosophila embryo expressing the kinesin-14 motor Ncd-GFP during prometaphase phase 1. This image stack is original data contributing to Fig. 1 "Prometaphase spin...

Image shows a z-series of a mouse ES cell observed using 3D immuno-FISH. The ES cells carried a multi-copy insertion of an alpha-globin BAC. H3K9me3 immunostaining (red) is shown in comparison to vec...
