  text: Contractile actomyosin rings drive various fundamental morphogenetic processes
    ranging from cytokinesis to wound healing. Actomyosin rings are generally thought
    to function by circumferential contraction. Here, we show that the spreading of
    the enveloping cell layer (EVL) over the yolk cell during zebrafish gastrulation
    is driven by a contractile actomyosin ring. In contrast to previous suggestions,
    we find that this ring functions not only by circumferential contraction but also
    by a flow-friction mechanism. This generates a pulling force through resistance
    against retrograde actomyosin flow. EVL spreading proceeds normally in situations
    where circumferential contraction is unproductive, indicating that the flow-friction
    mechanism is sufficient. Thus, actomyosin rings can function in epithelial morphogenesis
    through a combination of cable-constriction and flow-friction mechanisms.

  advice and the service facilities of the IST Austria and MPI-CBG for continuous
  help. M.B., G.S., S.W.G., and C.-P.H. synergistically and equally developed the
  presented ideas and the experimental and theoretical approaches. M.B. and P.C. performed
  the experiments; G.S. developed the theory; and R.H., F.O., and J.R. contributed
  to the experimental work. This work was supported by a grant from the Fonds zur
