- cell-to-cell signaling
- listen (sel-too-sel SIG-nuh-ling)
- The transfer of information from one cell to another. Cells signal each other by direct contact with each other or by the release of a substance from one cell that is taken up by another cell. Cell-to-cell signaling is important for cells to grow and work normally. Cells that lose the ability to respond to signals from other cells may become cancer cells. Also called cell-cell signaling and intercellular communication.
