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...

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...

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...
