8 million cells: virtual embryo shows organs forming in exquisite detail Model used to create a cellular ‘hologram’ of a mouse embryo could be used to visualize development in any species. By ...

B) Time-lapse images of mouse embryos through the 8-cell stage showing EZRIN-RFP fluorescence, with apical domains indicated by the white arrowhead, and times post-8-cell stage division on each image.

Results Asynchrony in the timing of embryo polarization To determine whether the timing of cell polarization affects subsequent embryo morphogenesis, we injected both blastomeres of 2-cell embryos ...
