A stem cell–derived human embryo model at a developmental stage equivalent to that of a human embryo at day 12 has all the compartments typical of this stage. The top sphere contains the part that will become the embryo itself, capped by the amnion; the bottom sphere is the yolk sac; the interface between them is a critical structural feature of human embryonic development. The two spheres are encapsulated by a cellular layer that will become the placenta
