Yolk syncytial layer cell nuclei exhibit convergence and extension behaviors during late gastrulation. Video made available by Mark Cooper through Zebrafish - The Living Laboratory.

Using a variant of miniSOG, a genetic probe for correlated light and electron microscopy (CLEM), we determined the form, fine structure and quantified the distribution of melanopsin-expressing retinal...

Zebrafish embryo at 75% epiboly. The view is from the animal pole. The focal plane is deep within the blastoderm. The focal plane changes as the embryo rolls during the sequence. The fluorescent lipid...

This study of the zebrafish eye is a series of four images taken at increasing magnifications. The first image is the SEM block face of the zebrafish eye. This is followed by a second image that is ...

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 ...

Epiboly movements of yolk syncytial layer (YSL) nuclei during gastrulation from a dorsal-vegetal pole view. A marginal band of nuclei moves toward the vegetal pole during epiboly, while some nuclei mo...

Scanning electron microscope image of Nicotiana alata stem cross section. Image shows outer epidermal layer, followed by the cortex and then large vascular bundles. The vascular bundles contain the ph...

Timelapse shows yolk syncytial layer (YSL) nuclear migration on the ventral side during gastrulation. Divergence of YSL nuclei away from ventral midline can be seen. As epiboly ends and blastopore clo...

Timelapse of dorsal yolk syncytial layer (YSL) nuclear movements during zebrafish gastrulation. A marginal band of YSL nuclei undergo epiboly toward the vegetal pole while internal-YSL (I-YSL) nuclei ...
