LEUKEMIA VIRUS-TUMOR CELL RELATIONSHIP

II. POSSIBLE EFFECT OF NTF SARCOMA ON ACTIVITY AND MULTIPLICATION OF FRIEND VIRUS

Abstract

The sarcoma discussed in the first paper of this series (59(6) p. 537) was found to have no inhibiting effect on the Friend virus in vitro and that the presence of growing sarcoma does not suppress the development of the characteristic splenomegaly in mice inoculated with the Friend virus, supporting the contention that the early association of the virus with the sarcoma was merely fortuitous.
