Tissues are essentially made of epithelial cells that form monolayers. During development, cells can sometimes leave these monolayers through a process called epithelial-mesenchymal transition. This process corresponds to the extrusion of a cell out of the tissue and its transformation into a migratory cell. In a study published in the journal Nature Communications, Magali Suzanne's team from LBCMCP-CBI shows that by extricating themselves from this monolayer, cells can deform their original tissue, thus actively participating in tissue remodeling during development.
