Curvature gradient drives polarized tissue flow in the Drosophila embryo
Tissue flow during morphogenesis is commonly driven by local constriction of cell cortices,
which is caused by the activation of actomyosin contractility. This can lead to long-range …

Attachment of the blastoderm to the vitelline envelope affects gastrulation of insects
During gastrulation, physical forces reshape the simple embryonic tissue to form the
complex body plans of multicellular organisms. These forces often cause large-scale …

Anisotropy links cell shapes to tissue flow during convergent extension
Within develo** embryos, tissues flow and reorganize dramatically on timescales as short
as minutes. This includes epithelial tissues, which often narrow and elongate in convergent …

Viscoelastic dissipation stabilizes cell shape changes during tissue morphogenesis
Tissue morphogenesis relies on the production of active cellular forces. Understanding how
such forces are mechanically converted into cell shape changes is essential to our …

Curling of epithelial monolayers reveals coupling between active bending and tissue tension
Epithelial monolayers are two-dimensional cell sheets which compartmentalize the body
and organs of multicellular organisms. Their morphogenesis during development or …
