Fluorescent microscopy image of an embryo model representing four tissue layers of this developmental stage. Cyan-labeled cells are clustered at the top of an ovoid structure, underneath them are yellow-labeled cells and under them red-labeled cells, and surrounding all three layers are white labeled cells.
