<h2>Density dependent </h2>
Explanation:
Density dependent inhibition is the process exhibited by most normal (anchorage dependent) animal cells in culture that stop dividing once a critical cell density is reached
The critical density is considerably higher for most cells than the density at which a mono-layer is formed
As cells become more numerous, the cell surface proteins of one cell contact the adjoining cells and they signal each other to stop dividing
Normal cells proliferate until they reach finite density but cancer cells are not sensitive to density dependent inhibition
