The process then repeats in what is called the cell cycle. Cells regulate their division by communicating with each other using chemical signals from special proteins called cyclins. These signals act like switches to tell cells when to start dividing and later when to stop dividing. I don't understand what you are saying, but hope this helps!
This is how healthy cells know when to stop dividing. and a process called contact inhibition is when normal, healthy cells are touching other cells on all sides, they have a red light in the cell cycle and do not divide
