Embryonic development

Researchers used color-coded proteins to reveal the identity of the cells in the organoids they produced. In four organoids that simulate the embryo’s central nervous system, the magenta marks proteins associated with the development of the forebrain and the midbrain, the green, the hindbrain and the red, the center of the spinal cord

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
