Phase Separation (IMAGE) The Hebrew University of Jerusalem Caption Within the nucleus of an embryonic stem cell (depicted on the left), HP1α bodies can be observed. These bodies exhibit phase separation, forming distinct liquid sub-domains with varying densities, as represented by the light blue and blue regions, respectively. Analogously, this phase separation can be likened to a drop of oil suspended in water (top image) or to dense crowds in a public space (bottom right). The borders between denser and less dense areas are highlighted in green and red.
