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

Video of zebrafish embryo development from a 2-cell egg to fish larva. Images were collected using confocal microscopy. Honorable Mention, 2011 Olympus BioScapes Digital Imaging Competition®.

Arabidopsis thaliana (thale cress) embryos imaged with confocal microscopy. Honorable Mention, 2009 Olympus BioScapes Digital Imaging Competition®.

Morphogenesis of the ventral yolk syncytial layer (YSL) from sphere stage to the end of gastrulation. The last round of nuclear division occurs before marginal band contraction and epiboly begins. As ...

Timelapse of dorsal yolk syncytial layer (YSL) nuclei and blastoderm morphogenesis from sphere stage (late blastula) to 1 somite stage. Top panel shows Nomarski movie of blastoderm morphogenesis inclu...

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...

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...

Scanning electron microscope image of Strongylocentrotus drobachiensus [sea urchin] gastrula. This is a higher magnification image of CIL39765. The embryo was split open to reveal a nice cross-section...
