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...

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 ...

Zebrafish embryo at 80% epiboly. The initial frame shows the junction of the enveloping layer with the yolk cell. The next frame is at a focal plane deeper within the embryo. The blastoderm margin is ...

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)...

Dome-stage Zebrafish embryo. The animal pole is at the bottom of the image. The yolk syncytial layer shows two tiers of nuclei. As the sequence begins, the yolk syncytial layer narrows. The view then ...

Nomarski/confocal projection shows animal pole of view of head anlage and underlying movements of yolk syncytial layer (YSL) nuclei (bright spots). Nuclei extend and flow through animal pole region to...

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 ...

Figure 370 from Chapter 15 (Cytoplasmic Inclusions) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Ectoderm cell from a blastula of Rana pipiens. This cell shows a number of yolk platelets, lipid dro...

Confocal micrograph of a transgenic zebrafish embryo at 24 hours post-fertilization, showing expression of the fusion protein PARD3_GFP. PARD proteins, which were first identified in C. elegans, are e...
