Self-assembled active actomyosin gels spontaneously curve and wrinkle similar to biological cells and tissues
Living systems adopt a diversity of curved and highly dynamic shapes. These diverse
morphologies appear on many length scales, from cells to tissues and organismal scales …

Generic theory of interacting, spinning, active polar particles: A model for cell aggregates
We present a generic framework for describing interacting, spinning, active polar particles,
aimed at modeling dense cell aggregates, where cells are treated as polar, rotating objects …

Learning a phenomenological theory for contact-interactions between motile cells from collision experiments
T Brandstätter, E Brieger, DB Brückner… - arxiv preprint arxiv …, 2024 - arxiv.org
The migration behavior of colliding cells is critically determined by transient contact-
interactions. During these interactions, the motility machinery, including the front-rear …

Asymmetry of acto-myosin cortices as active fluids shape cells in organoids
T Guyomar, L Lu, T Hiraiwa, D Riveline - bioRxiv, 2024 - biorxiv.org
Cell cortex is a thin sheet of actin cytoskeleton spanning cell boundaries with rich out-

Rotational migration in human pancreatic ductal organoids depends on actin and myosin activity
Rotational migration is one specific form of collective cell migration when epithelial cells are
confined in a spherical geometry, such as in the epithelial acini. This tissue-level rotation …
