initiated by Paul Ehrenfest in 1912
currently organized by Vincenzo Vitelli & Koenraad Schalm (read about its history)

Jacques Prost (Curie Institute)

Long-time tissue dynamics and multicellular spheroids

After introducing the notion of homeostatic pressure, I will subsequently introduce dynamical equations, which exhibit fluid like behavior on time scales long compared to duplication and apoptosis times, in the vicinity of homeostatic conditions. Subsequently, I will describe stress-clamp experiments, which provide numbers on the effects of stress on cell division and apoptosis and introduce the idea of "active" tissue, which allows us to understand some aspects of experimental results. Then I will describe a dynamical transition in nematic epithelia which we predicted about ten years ago in active gels. Eventually, I will shortly give some conjectures about long time electric effects on polar tissues.


The Colloquium Ehrenfestii takes place Wednesday evenings starting at 19:30 hours in the main auditorium of the Oort building. Before the Colloquium, there is a common dinner in the canteen located on the ground floor of the Oort building. This dinner starts at 18:00 hours sharp and is free of charge, under the condition that one attends the colloquium and that one has made a reservation before noon on the Tuesday preceding the colloquium. [Registration may close earlier, when 80 persons have signed up]
