Transformation of normal bone-marrow cells by a leukaemic cell line associated with a presumptive new human virus

Abstract

Intracytoplasmic leukovirus-like bodies were found in the cells and culture medium of a T-cell lymphoblast line established from a leukaemic patient. When the cells were lethally irradiated and added to normal bone-marrow cells the latter were transformed into continuous replication and produced the same types of virus-like particle.
