Transformation of Mouse Macrophages by Simian Virus 40

Lawrence B Stone 1, Kenneth K Takemoto 1
PMCID: PMC376167  PMID: 4320698

Abstract

Studies were undertaken to prove that simian virus 40 (SV40) can transform the mouse macrophage, a cell type naturally restricted from deoxyribonucleic acid (DNA) replication. Balb/C macrophages infected with SV40 demonstrated T-antigen production and induced DNA synthesis simultaneously. In the absence of apparent division, these cells remained T antigen-positive for at least 45 days. SV40 could be rescued from nondividing, unaltered macrophages during the T antigen-producing period. Proliferating transformants appeared at an average of 66 days post-SV40 infection. Established cell lines were T antigen-positive and were negative for infectious virus, but yielded SV40 after fusion with African green monkey kidney cells. Their identity as transformed macrophages was substantiated by evaluation of cellular morphology, phagocytosis, acid phosphatase, β1c synthesis, and aminoacridine incorporation.
