How cells receive and respond to signals from their surroundings. On one hand, cell signaling regulates gene expression and controls the cell fate (proliferation, motility, differentiation and programmed cell death, or apoptosis).. Introduction. Cell signaling: . a biological mechanism that occurs in cells which gives cells an ability to receive or generate the signals in response to their surrounding environment..
