Query: Elasticity, stability, and quasi-oscillations of cell-cell junctions in
  solid confluent epithelia   Macroscopic properties and shapes of biological tissues depend on the
remodelling of cell-cell junctions at the microscopic scale. We propose a
theoretical framework that couples a vertex model of solid confluent tissues
with the dynamics describing generation of local force dipoles in the
junctional actomyosin. Depending on the myosin-turnover rate, junctions either
preserve stable length or collapse to initiate cell rearrangements. We find
that noise can amplify and sustain transient oscillations to the fixed point,
giving rise to quasi-periodic junctional dynamics. We also discover that
junctional stability is affected by cell arrangements and junctional rest
tensions, which may explain junctional collapse during convergence and
extension in embryos.
