A 2.75 hour Zebrafish embryo; the same embryo as in CIL 37403 --later in blastoderm development. The video shows dynamics in a perisagital section of the embryo. The sequence shows blastomeres dividin...

Sixteen cell stage Zebrafish embryo. The first frame shows cells at metaphase. The sequence covers the next four cell cycles. In each prophase, there is a rapid onset of yolk platelet motility. Yolk m...

Four cell stage zebrafish embryo, stained with 100 micromolar Bodipy 505/515. In the upper portion of the image, the yolk cell contains large spherical yolk platelets. The blastomeres undergoing merob...

4D data set of yolk syncytial layer nuclear movements. Movie shows z-series stacks sequentially through time. Numbers label individual nuclei so they can be tracked in 3D space at each time point. Vi...

Confocal projection of Zebrafish yolk cells expressing H2B-cherry (red) to mark the nucleus and a GFP membrane marker (green) to show the outline of the cells.

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

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

Visualization of yolk syncytial layer (YSL) nuclei in living zebrafish embryos. Sytox Green, a membrane-impermiant vital nuclear stain, was injected into the yold cell of late blastula (sphere stage)...

Timelapse of yolk syncytial layer (YSL) nuclear movements during gastrulation from a dorsal-anterior view shows epiboly, early animal pole directed movements of I-YSL nuclei, and convergence and exten...

Uptake of yolk protein into coated vesicles (arrows) at the periphery of oocytes of the cockroach Periplaneta americana. Yolk protein binds to regions of the membrane with a prominent glycocalyx. Beca...
