Spinning disk confocal time-lapse imaging of the first mitosis in a C. elegans embryo expressing GFP-KNL-2 (strain OD31) in which KNL-1 has been depleted by RNAi. Discrete foci of GFP signal within th...

Early embryonic divisions in Drosophila are syncytial. Nuclei undergo mitosis synchronously for the first 14 nuclear cycles, followed by cellularization (Foe and Alberts, 1983). At nuclear cycle 10, n...

Zebrafish Embryo, from tailbud to 16-hour stage, stained with 100 micromolar Bodipy-Ceramide. Bodipy-Ceramide permeates the enveloping layer epithelium of the embryo, accumulating in the interstitial ...
