Here, we provide a theoretical framework for the homeostasis of stem-cell-containing epithelial tissues using mechanical equations, which describe the size of the tissue and kinetic equations, which describe the interconversions of the cell populations. We show that several features, such as the evolution of stem cell fractions during intestinal development, the shape of a developing intestinal wall, as well as the increase in the proliferative compartment in cancer initiation, can be studied and understood from generic modelling which does not rely on a particular regulatory mechanism. Finally, inspired by recent experiments, we propose a model where cell division rates are regulated by the mechanical stresses in the epithelial sheet. We show that pressure-controlled growth can, in addition to the previous features, also explain with few parameters the formation of stem cell compartments as well as the morphologies observed when a colonic crypt becomes cancerous. We also discuss optimal strategies of wound healing, in connection with experiments on the cornea."}],"publication_status":"published","issue":"93","publication":"Journal of the Royal Society Interface","title":"Growth homeostatic regulation and stem cell dynamics in tissues","doi":"10.1098/rsif.2013.0895","author":[{"orcid":"0000-0001-6005-1561","full_name":"Hannezo, Edouard B","first_name":"Edouard B","id":"3A9DB764-F248-11E8-B48F-1D18A9856A87","last_name":"Hannezo"},{"full_name":"Prost, Jacques","first_name":"Jacques","last_name":"Prost"},{"first_name":"Jean","full_name":"Joanny, Jean","last_name":"Joanny"}],"_id":"926","date_created":"2018-12-11T11:49:14Z","month":"04","citation":{"chicago":"Hannezo, Edouard B, Jacques Prost, and Jean Joanny. “Growth Homeostatic Regulation and Stem Cell Dynamics in Tissues.” <i>Journal of the Royal Society Interface</i>.
