MAPK and MEK are intracellular signaling proteins that mediate cell division induced by growth factors. When mutations in the normal MAPK and MEK genes result in an abnormally high level of MAPK and MEK activity and an increased rate of cell division, then the mutated gene is called a(n)

induction of epithelial cells by paracrine signaling from mesenchymal cells.

Explanation:

Mesenchymal stem cells can be found in bone marrow and are vital in making and the repairing or skeletal tissues.

Based on the information given in the question, the developmental concept that the example best describe is the induction of epithelial cells by paracrine signaling from mesenchymal cells.
