Even though the axon completely controlled the synthesis of these proteins, the axon alone isn't enough for myelinogenesis. As the experiment progressed, it became more evident that membrane-membrane interactions between axons somehow promoted the synthesis of the essential proteins P1, P2, and P0. It is likely that axons from myelinated fibers are able to induce Schwann cell myelin protein synthesis throughout the adult life.
