How the cytoplasm separates from the yolk

The segregation of yolk from the surrounding cytoplasm in the very early fish embryo is a key process for the development of the fish larva. To identify its underlying mechanisms, biologists at the Institute of Science and Technology Austria (IST Austria) teamed up with their colleagues from theoretical physics. The discovery: Actin dynamics in the bulk of the cell drive phase segregation in zebrafish oocytes.
