English term or phrase:J:wo factors
It appeared that coal tar did not directly induce the transformation in vitro of the normal cells into tumor cells and that its mode of action differs in a radical way from that of Rous' substance. Therefore, I supposed that coal tar could be considered as the probable precursor of a substance analogous to Rous' principle which develops in the tissues of the animal under the influence of J:wo factors, local irritation, and a modification of the blood plasma produced by coal tar.
