Cells use mechanisms of cell-to-cell communication also to compete with each other. This process has been termed “cell competition”. Cells within tissues are in constant interaction with each other and sense each other’s presence. When a cell acquires specific mutations though, other cells may push them to die. Although the intricate nature of this process is currently being debated in the field, the mechanism is highly conserved and comes with biological relevance. It is believed that such mechanisms could be used to prevent dangerous, mutant cells from acquiring secondary mutations that can transform them into malignant cancer cells. Once surrounding cells detect an issue with their neighbor, they may release signals that impose death on the “loser” cell.
