In normal tissues , strict control of tissue size is achieved by regulating cell numbers . The mechanism that controls total cell number is known as contact inhibition of growth and it depends on the NF2/Merlin pathway . Negative regulation of this pathway by deleterious mutations or by oncogenes results in cell transf... | [
