Explanation:
Detailed explanation-1: -Cells stop dividing for several reasons, including: A lack of positive external signals. The cell senses that it is surrounded on all sides by other cells-contact dependent (density dependent) inhibition. Most cells seem to have a pre-programmed limit of the number of times they can divide.
Detailed explanation-2: -When a cell comes into contact with another cell, the two cells attempt to change their locomotion in different directions to avoid a repeat of the same in the future. If they cannot avoid it, they cease their growth and division.
