A side-by-side comparison shows how six types of vertex models for living tissues exhibit similar mechanical behavior, with stiffening governed by cell shape — suggesting the rigidity transitions and viscoelastic responses of these models are universal. https://t.co/8ruFDpsB82

Excited to share our new paper in @PRX_Life! We uncover universal viscoelastic behavior in different vertex models of biological tissues, explaining why so many models work so well. Enjoyed working with Ojan (co-first), Liz & Lisa on this! See https://t.co/xLKrx2ZkGI
A systematic comparison of diverse cell packing models reveals shared mechanical rules that govern how tissues stiffen, yield, and reorganize — shedding light on the physical mechanisms behind #morphogenesis. Read the paper: https://t.co/8ruFDpt8XA

Simulations of cancer cell invasion reproduce experiments in microfluidic channels, showing how confinement, adhesion, and chemotaxis affect how cells break off from an invading front and rupture — behavior that can lead to #metastasis. Read the paper: https://t.co/WCcR4Fi355
