title: Charlotte Friend Memorial Lecture: murine leukemia virus (MuLV) tumorigenesis.
abstract: Recent analysis of over 500 lymphomas occurring in NFS.V mice, congenic for Akv-type ecotropic MuLV structural genes, has revealed that about 90% are of B cell lineage as determined by demonstration of clonal rearrangements of Ig heavy chain genes, phenotyping by immunocytochemistry or cytofluorometric analysis, and by site and morphology of tumor. At least 40% of the B cell lymphomas were found to have their origin in the splenic marginal zone, a site only once before described for mouse lymphomas. Clonal somatic integrations of ecotropic MuLV occurred in 85% of tumors.
