TITLE: ELASTIC INSTABILITY IN A GROWING YEAST COLONY

ABSTRACT:
The selective adhesion between cells is believed to be the major driving force
behind the formation of tissues. The idea is that an aggregate of cells minimizes
the overall adhesive energy between the cell surfaces. We demonstrate in a model
experimental system that there exist conditions where a slowly growing tissue does
not minimize this adhesive energy. A mathematical model demonstrates that in this
regime the tissue morphology is determined by the competition between elastic and
surface energies.
