Abstract
Summary
When mice were inoculated with 3 carcinogenic compounds, they developed a transient antineoplastic (AN) response which was demonstrable by tissue culture technic. This AN phenomenon appeared to be chemically and genetically specific. The duration of the AN response to the 3 agents may represent the latent period of carcinogenesis, since the AN phenomenon disappeared when the tumor emerged. The interpretation of the AN phenomenon on an immunological basis is discussed.
