Microtubules in sand dollar embryo expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). Eight-cell sand dollar embryo; single microtubules gro...

Eight-cell purple urchin embryo expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). The embryo was treated with 20 µM nocodazole at time 00:...

One of eight cells in a slightly compressed sand dollar embryo expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). The embryo was treated wit...

16-cell purple urchin embryo with EMTB-3G (microtubules) in shown cyan and mC-H2B (chromatin) in yellow. The embryo is treated with 15 µM trichostatin A (TSA), an inhibitor of HDAC6 (a tubulin deace...

Zebrafish Notogenesis and Early Neurulation. Mediolateral intercalation produces convergent-extension of the notochordal rudiment. Cells within the center of the notochord elongate and are incorporate...

Transmission EM showing adherens junctions between cells of the enveloping layer of a 24 hr (prim-5) Zebrafish embryo. Specimens fixed in Karnofsky's (overnight at 4˚C) followed by postfixing in 4% ...

Zebrafish embryo undergoing cytokinesis. The embryo is expressing fixed EMTB-3GFP (microtubules-marker, green) and is labeled with phalloidin (actin marker, red) and Hoechst (DNA marker, blue). Note...

The time-lapse movie shows early development in the Lytechinus (sea urchin) embryo. Polarizing microscopy highlights the mitotic spindles which may show bright or dark contrast according to their orie...

Scanning EM of a 24 hr (prim-5) zebrafish embryo. Zebrafish were chemically fixed critically point dried, and sputter coated with gold/palladium. This image is part of a series taken by Bryan Crawfo...

Confocal image of the developing eye of a chick embryo. The dark region in the centre is the where the surface layer has invaginated to form the lens vesicle. The tissue surrounding this space is stai...
