The effect of methylcholanthrene on the denervated skin of Strain A mice was studied. A band of skin was denervated by the unilateral resection of the lower six thoracic dorsal root ganglia in continuity with dorsal and ventral nerve roots and peripheral nerve trunks. Suitable controls indicated that methylcholanthrene caused a more rapid appearance of tumors in the mice with denervated skin. The possible mechanisms for this are discussed.
