Dynamics of Cellular and Syncytial Endoderm. An ectopic embryonic axis was induced by injecting a marginal blastomere of a 32-cell stage embryo with TARAM-A (Tar*, a receptor for Nodal-like ligands) R...

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...

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...

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 ...

Figures 417 (upper) and 418 (lower) from Chapter 16 (Cytoplasmic matrix and cytoskeleton) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. A marginal bundle of microtubules is associated with the ellipti...

A normal X. laevis blastomere expressing three tandem GFPs fused to the ensconsin microtubule-binding domain (EMTB-3G; Faire et al., 1999). Single microtubules extend to the cortex, even in these larg...

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...

Figure 416 from Chapter 16 (Cytoplasmic matrix and cytoskeleton) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. The marginal band of an erythrocyte from the toadfish Opsanus Tau contains a circumferen...

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 ...

Electron micrographs show examples of pinocytosis in endothelial cells of blood vessels in the cat myocardium (panels A,B,C and H), and from the choroid rete of the bowfin fish eye. Both types of cell...
