  text: As developing tissues grow in size and undergo morphogenetic changes, their
    material properties may be altered. Such changes result from tension dynamics
    at cell contacts or cellular jamming. Yet, in many cases, the cellular mechanisms
    controlling the physical state of growing tissues are unclear. We found that at
    early developmental stages, the epithelium in the developing mouse spinal cord
    maintains both high junctional tension and high fluidity. This is achieved via
    a mechanism in which interkinetic nuclear movements generate cell area dynamics
    that drive extensive cell rearrangements. Over time, the cell proliferation rate
    declines, effectively solidifying the tissue. Thus, unlike well-studied jamming
    transitions, the solidification uncovered here resembles a glass transition that
    depends on the dynamical stresses generated by proliferation and differentiation.
    Our finding that the fluidity of developing epithelia is linked to interkinetic
    nuclear movements and the dynamics of growth is likely to be relevant to multiple
    developing tissues.
