Abstract

The shape of cells to come During development, changes in individual cell shape drive the overall organization of organs and tissues. Now a study of the dynamics of cell behaviour during fruit fly development reveals a previously unknown ratchet-like mechanism that drives cell shape change. Gastrulation in the Drosophila embryo involves the apical constriction of ventral cells, which induces a ventral furrow and invagination of the mesoderm. This new work shows that the apical constriction of ventral cells is pulsed: repeated constrictions are interrupted by pauses in which the constricted state of the cells in maintained. These pulses are powered by actin–myosin contractions and are dependent on the expression of a transcription factor Snail, whereas the constricted state is stabilized by another transcription factor, Twist.
