This movie shows the "yolk flash". The apparently whole-embryo calcium pulse appears to initiate over a widespread area of blastoderm, possibly earliest at the animal pole, and then spreads first to ...

This movie displays an archetypal online digital atlas of the quail embryo based on microscopic magnetic resonance imaging. The atlas is composed of two modules: (1) images of fixed in ovo and ex ovo ...

Pre-wave pulse (PWP). The apparently whole-embryo calcium pulse appears to initiate (the PWP region on the wave graphs) over a widespread area of blastoderm, possibly earliest at the animal pole, and...

This movie is of a Drosophila melanogaster early embryo (cycle 12) expressing GFP-tubulin (green) and injected with Rhodamine-labeled histones (red) and 8mg/ml RanT24N, a dominant negative inhibitor o...

A confocal 4D-stack from a transgenic Drosophila embryo expressing lamin-GFP (green) and injected with rhodamine-conjugated tubulin (red) during surrounding the prometaphase (phase I and II) spindle. ...

Developing fruit fly nerve cord. The glial cells (black dots) and nerve cells (brown bands) in this developing fruit fly nerve cord formed normally despite the absence of the SPITZ protein, which bloc...

Transverse section through the neural tube of an early stage chick embryo. The brown stain shows the neurofilament in the axons of the commisural neurons (running down the sides of the neural tube) an...

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...

3D stereoscopic projection of a z-stack of confocal images of an Arabidopsis thaliana plant embryo that was fixed, cleared and stained. Red/Green 3D lenses required for stereoscopic view. Honorable Me...

Short timelapse movie of prechordal plate, hypoblast, and yolk syncytial layer (YSL) nuclear movements during 80-90% epiboly. The prechordal plate and notochord can be seen as a tighter clump of cells...
