We posted a joint manuscript between the Manning group (Sussman, Manning) and the Gardel lab (Devaney, Gardel) on BioRXiv, titled, “Cell division Rate Controls Cell Shape Remodeling in Epithelia”, https://www.biorxiv.org/content/10.1101/804294v1. We use a combination of vertex modeling and experiments to demonstrate that cell shape (and not number density) governs cell movements in epithelia, and that cell divisions generate the dominant active stress fluctuations that cause cell movements.
