Designing graphical embryo geometries from confocal microscopy images of Nematostella vectensis. A D) Fluorescent Nematostella embryos in subsequent stadia of gastrulation stained with phalloidin (green) to label actin and propidium iodide (red) to label nuclei (taken from [13]). Hours of development times are indicated in the lower left corner of each panel. E H) Average geometries constructed from shown and additional confocal images [12].
