title: Inhibition of simian virus 40-induced tumors by antisera to fetal hamster tissue.
abstract: Growth of tumors induced in hamsters with simian virus 40 (SV40) or SV40-transformed cells was inhibited by antisera to fetal hamster thymocytes or liver. This result was in contrast to the enhancement of tumor growth by antisera to adult hamster thymocytes.
