The paper shows that during Drosophila dorsal closure, apical surface expansion in dorsal cells, regulated by Rab11 and the Dpp/Brinker pathway, confines tissue deformation under stretch.

The paper shows chromatin compaction in Drosophila neurons follows a power law with nuclear volume during interphase and mitosis, regulated by molecular cues and phase separation.

The paper shows that wound healing in Drosophila involves reversible chromatin-lamina dewetting triggered by mechanical changes, leading to cellular contraction and tissue repair.

The paper applies controlled forces to microparticles in embryos to measure tissue mechanical properties and finds a rapid softening during Drosophila cellularization.

The paper shows that dorsal closure in Megaselia abdita uses two microtubule-based seaming events instead of the single event in Drosophila, highlighting a morphogenetic evolution without changing signaling pathways.
