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 ...

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

Individual deep cell moving by circus movements. Fundulus heteroclitus(killifish) embryo injected with GFP-actin plasmid at 1-cell stage, filmed during gastrulation. Image made available through Zebra...

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...

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...

A live developing sea urchin embryo was imaged using differential contrast microscopy to enhance cellular details. Each minute a through focal series (Z-series) of micrographs was acquired to capture...

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...

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

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 ...
