Neighborhood dispute among cells: whichever successfully exerts force wins

Trial of strength at the cellular level: cells are in constant competition with each other and so eliminate diseased or unwanted cells. Cell competition is therefore a central principle for maintaining the health of tissues and organs. Researchers have investigated the success factors of superior cells and discovered a previously unknown winning strategy in mechanical cell competition. They identified a variety in the ability of cells to exert mechanical forces onto other cells as the decisive regulator. With their results recently published in ‘Nature Materials,’ the research team from Germany, France and Denmark challenges the classical interpretation of cell competition.
